In the structural design of airframes and buildings, probability-based procedures are used to mitigate the risk of failure as well as produce cost-effective designs. This book introduces the subject of probabilistic analysis to structural and fire protection engineers and can also be used as a reference to guide those applying this technology. In addition to providing an understanding of how fire affects structures and how to optimize the performance of structural framing systems, Probability-Based Structural Fire Load provides guidance for design professionals and is a resource for educators. The goal of this book is to bridge the gap between prescriptive and probability-based performance design methods and to simplify very complex and comprehensive computer analyses to the point that stochastic structural fire loads have a simple, approximate analytical expression that can be used in structural analysis and design on a day-to-day basis. Numerous practical examples are presented in step-by-step computational form.

Excerpt: ...one already mentioned between Pittsburg and Erie, affording very little comfort or facility to those who have the misfortune to be obliged to travel upon them. But on the construction of one or two lines of road, the Americans have bestowed a little more attention. The most remarkable of them is that called the "National Koad," stretching across the country from Baltimore to the State of Illinois, a distance of no less than 700 miles, an arduous and extensive work, which was constructed at the expense of the government of the United States. The narrow tract of land from which it was necessary to remove the timber and brushwood for the passage of the road measures eighty feet in breadth; but the breadth of the road itself is only thirty feet. Commencing at Baltimore, it passes through part of the State of Maryland, and entering that of Pennsylvania, crosses the range of the Alleghany Mountains after which, it passes through the States of Virginia, Ohio and Indiana, to Illinois. It is in contemplation to produce this line of road to the Mississippi at St Louis, where, the river being crossed by a ferry-boat stationed at that place, the road is ultimately to be extended into the State of Missouri, which lies to the west of the Mississippi. The "Macadamized road," as it is called, leading from Albany to Troy, is another line which has been formed at some cost, and with some degree of care. This road, as its name implies, is constructed with stone broken, according to Macadam's principle. It is six miles in length, and.has been formed of a sufficient breadth to allow three carriages to stand abreast on it at once. It belongs to an incorporated company, who are said to have expended about L.20,000 in constructing and upholding it....

Distance from the mainland, and difficulties in landing are the main obstacles in such cases, and were the causes of the preference for iron being given in the construction of the Roches-Douvres lighthouse. Bock Lighthouses. The really serious difficulties in lighthouse construction arise when a lighthouse has to be built on an isolated rock in the sea, at a distance from the mainland, where no shelter for the workmen can be provided, where the materials have to be landed on the rock as they are required, and more especially when the rock is covered by the tide, and the approach is difficult, uncertain, and even dangerous at times. The important considerations for these lighthouses are the level of the rock in relation to the sea level, the extent of the rock and its hardness, the exposure of the site, and its distance from the nearest suitable port for the conveyance of materials. In many cases the rock forming the foundation for the lighthouse is below high water, of which all the illustrations given are instances. (Plate 9, Figs. 1 to 9.) In some places the rock rises very little above low-water level, and is restricted in area, as at Bell Rock, Minot's Ledge, Des Barges, 364 Difficulties-in erecting Rock Lighthouses. pt. 1. and Ar-men; whilst at Spectacle Reef in Lake Huron, where there is no rise of tide, the rock is several feet below the surface of the water. Unless the rock is hard, compact, and without f1ssures, it is inexpedient to erect a lighthouse upon it, as the tower increases the surf on the rock, and by its weight on a small base, and the shocks which it transmits to its foundations, would soon impair any unsound portions of the rock. The strokes of the sea against Smeaton's Eddystone lighthouse caused the shaking ...

This text introduces the basic equations of the theory of structures. Conventional presentations of these equations follow the ideas of elastic analysis, introduced nearly two hundred years ago. The present book is written against the background of advances made in structural theory during the last fifty years, notably by the introduction of so-called plastic theory. Tests on real structures in the twentieth century revealed that structural states predicted by elastic analysis cannot in fact be observed in practice, whereas plastic ideas can be used to give accurate estimates of strength. Strength is discussed in the first part of this book without reference to equations of elastic deformation. However, the designer is concerned also with stiffness, for which elastic analysis is needed, and the standard equations (suitable, for example, for computer programming) are presented. Finally, stability is analyzed, which again is essentially an elastic phenomenon, and it is shown that a higher factor of safety is required to guard against buckling than that required to guarantee straightforward strength. The emphasis throughout is on the derivation and application of the structural equations, rather than on details of their solution (nowadays best done by computer), and the numerical examples are deliberately kept simple."

Encouraging creative uses of reinforced concrete, Principles of Reinforced Concrete Design draws a clear distinction between fundamentals and professional consensus. This text presents a mixture of fundamentals along with practical methods. It provides the fundamental concepts required for designing reinforced concrete (RC) structures, emphasizing principles based on mechanics, experience, and experimentation, while encouraging practitioners to consult their local building codes. The book presents design choices that fall in line with the boundaries defined by professional consensus (building codes), and provides reference material outlining the design criteria contained in building codes. It includes applications for both building and bridge structural design, and it is applicable worldwide, as it is not dependent upon any particular codes. Contains concise coverage that can be taught in one semester Underscores the fundamental principles of behavior Provides students with an understanding of the principles upon which codes are based Assists in navigating the labyrinth of ever-changing codes Fosters an inherent understanding of design The text also provides a brief history of reinforced concrete. While the initial attraction for using reinforced concrete in building construction has been attributed to its fire resistance, its increase in popularity was also due to the creativity of engineers who kept extending its limits of application. Along with height achievement, reinforced concrete gained momentum by providing convenience, plasticity, and low-cost economic appeal. Principles of Reinforced Concrete Design provides undergraduate students with the fundamentals of mechanics and direct observation, as well as the concepts required to design reinforced concrete (RC) structures, and applies to both building and bridge structural design.

Between July 1761, when a navigable aqueduct opened on the Bridgewater Canal at Barton-upon-Irwell, and July 1963, date of the completion of the Thelwall Viaduct on the M6 near Warrington, Britain would see the construction of a great number of aqueducts and viaducts. Emblems of the industrial age, from unassuming arches built to carry canals over streams to immense multi-span structures conveying railways across estuaries or roads above plains, each bridge has its own distinctive history and character. In this book, Victoria Owens takes a look at the fascinating history behind some of the most iconic landmarks of the British landscape, charting the ambitions of the engineers who designed them, the endurance of the labourers who built them and the impact that they have made upon the face of the nation. Numerous photographs illustrate the text, and grid references give a guide to the bridges' locations.

Costing at the time GBP1.8 million to complete, the Severn Tunnel was a Victorian engineering triumph, and for over a century it remained the longest rail tunnel in Britain. Construction had begun in 1873 but came to a standstill after the workings were inundated by water in 1879. An accomplished civil engineering contractor, Thomas Andrew Walker (1828-89) had worked on railways in Canada, Russia and Africa as well as on London's new underground lines; he was therefore well qualified to complete the Severn Tunnel, which was achieved in 1886. First published in 1888, Walker's first-hand account of the problematic project remains an engaging source for railway and engineering historians, and its detailed account of the ground encountered will also interest geologists. Replete with plans and maps, reissued here is the second edition of 1890, the year following Walker's death, which is likely to have been hastened by overwork.

This textbook, first published in 2006, provides the student of aerospace, civil and mechanical engineering with all the fundamentals of linear structural dynamics analysis. It is designed for an advanced undergraduate or first-year graduate course. This textbook is a departure from the usual presentation in two important respects. First, descriptions of system dynamics are based on the simpler to use Lagrange equations. Second, no organizational distinctions are made between multi-degree of freedom systems and single-degree of freedom systems. The textbook is organized on the basis of first writing structural equation systems of motion, and then solving those equations mostly by means of a modal transformation. The text contains more material than is commonly taught in one semester so advanced topics are designated by an asterisk. The final two chapters can also be deferred for later studies. The text contains numerous examples and end-of-chapter exercises.

This short book analyses the dynamic stability with respect to small perturbations, as well as the local damage of geometrically nonlinear elastic, spatially curved, open section beams with axial precompression. Transient waves, which are the surfaces of strong discontinuity and wherein the stress and strain fields experience discontinuities, are used as small perturbations; in so doing the discontinuities are considered to be of small magnitude. Such waves are initiated during low-velocity impacts upon thin-walled beams. The theory of discontinuities and the method of ray expansions which allow one to find the desired fields behind the fronts of the transient waves in terms of discontinuities in time-derivatives of the values to be found, are used as the methods of solution for short-time dynamic processes. The example of using the ray expansions for analyzing the impact response of spatially curved thin-walled beams of open profile is demonstrated by solving the problem about the normal impact of an elastic hemispherical-nosed rod upon an elastic arch representing itself a channel-beam curved along an arc of the circumference. The influence of the initial stresses on the dynamic fields has been investigated.

This lively introduction to geologic fracture mechanics provides a consistent treatment of all common geologic structural discontinuities. It explores the formation, growth and interpretation of fractures and deformation bands, from theoretical, field and lab-based perspectives, bridging the gap between a general textbook treatment and the more advanced research literature. It allows the reader to acquire basic tools to interpret discontinuity origins, geometries, patterns and implications using many of the leading and contemporary concepts known to specialists in the field. Problem sets are provided at the end of each chapter, and worked examples are included within each chapter to illustrate topics and enable self-study. With all common geologic structures including joints, hydrofractures, faults, stylolites and deformation bands being discussed from a fresh perspective, it will be a useful reference for advanced students, researchers and industry practitioners interested in structural geology, neotectonics, rock mechanics, planetary geology, and reservoir geomechanics.

Thomas Stevenson (1818 1887) was the son of the engineer Robert Stevenson, and father of the writer Robert Louis Stevenson. Like his brothers David and Alan, he became a lighthouse designer, being responsible for over thirty examples around Scotland. Throughout his career he was interested in the theory as well as the practice of his profession, and published over sixty articles on engineering and meteorology. He was an international expert on lighthouses and harbour engineering. This work was first published in 1864 as a development of his article on harbours in the eighth edition (1857) of the Encyclopaedia Britannica, and considerably expanded in a second edition of 1874 which is reprinted here. Stevenson studied how the wind, waves and tides would act on the coastline and man-made structures, and the design of each harbour needed to take a wide range of factors into consideration.

This 2006 book presents a systematic introduction to the theory of parametric stability of structures under both deterministic and stochastic loadings. A comprehensive range of theories are presented and various application problems are formulated and solved, often using more than one approach. Investigation of an elastic system's dynamic stability frequently leads to the study of dynamic behaviour of the solutions of parametrically excited systems. Parametric instability or resonance is more dangerous than ordinary resonance as it is characterised by exponential growth of the response amplitudes even in the presence of damping. The emphasis in this book is on the applications and various analytical and numerical methods for solving engineering problems. The materials presented are as self-contained as possible, with all of the important steps of analysis provided in order to make the book suitable as a graduate-level textbook and especially for self-study.

Structural Analysis presents the theory and applications of structural analysis as it applies to trusses, beams, and frames. The reader-friendly, clear organization emphasizes developing the ability to model and analyze a structure in preparation for professional practice. The text is designed to ensure those taking their first course in this subject understand some of the more important classical methods of structural analysis, in order to obtain a better understanding of how loads are transmitted through a structure, and how the structure will deform under load. The large number of problems cover realistic situations involving various levels of difficulty. The 10th Edition features 30% new problems and an expanded discussion of structural modeling, specifically the importance of modeling a structure so it can be used in computer analysis. Newly added material includes an update to the ASCE/SEI 2106 specifications, a discussion of catenary cables, and further clarification for drawing moment and deflection diagrams for beams and frames.

This 2007 book concerns the vibration and the stability of slender structural components. The loss of stability of structures is an important aspect of structural mechanics and is presented here in terms of dynamic behavior. A variety of structural components are analyzed with a view to predicting their response to various (primarily axial) loading conditions. A number of different techniques are presented, with experimental verification from the laboratory. Practical applications are widespread, ranging from cables to space structures. The book presents methods by which the combined effects of vibration and buckling on various structures can be assessed. Vibrations and buckling are usually treated separately, but in this book their influence on each other is examined together, with examples when a combined approach is necessary. The avoidance of instability is the primary goal of this material.

This volume provides a concise, historical review of the methods of structural analysis and design - from Galileo in the seventeenth century, to the present day. Through it, students in structural engineering and professional engineers will gain a deeper understanding of the theory behind the modern software packages they use daily in structural design. This book also offers the reader a lucid examination of the process of structural analysis and how it relates to modern design. The first three chapters cover questions about the strength of materials, and how to calculate local effects. An account is then given of the development of the equations of elastic flexure and buckling, followed by a separate chapter on masonry arches. Three chapters on the overall behaviour of elastic structures lead to a discussion of plastic behaviour, and a final chapter indicates that there are still problems needing solution.

A good grasp of the theory of structures - the theoretical basis by which the strength, stiffness and stability of a building can be understood - is fundamental to structural engineers and architects. Yet most modern structural analysis and design is carried out by computer, with the user isolated from the processes in action. This book provides a broad introduction to the mathematics behind a range of structural processes. The basic structural equations have been known for at least 150 years, but modern plastic theory has opened up a fundamentally new way of advancing structural theory. Paradoxically, the powerful plastic theorems can be used to examine 'classic' elastic design activity, and strong mathematical relationships exist between these two approaches. Some of the techniques used in this book may be familiar to the reader, and some may not, but each of the topics examined will give the structural engineer valuable insight into the basis of the subject. This lucid volume provides a valuable read for structural engineers and others who wish to deepen their knowledge of the structural analysis and design of buildings.

The study of structural instability plays a role of primary importance in the field of applied mechanics. Despite the remarkable progresses made in the recent past years, the structural instability remains one of the most challenging topics in applied - chanics. Many problems have bee:: solved in the last decades but still many others remain to be solved satisfactorily. The increasing number of papers published in jo- nals and conferences organized by ECCS, SSRC, IUTAM, and EUROMECH strongly indicates the interest of scientists and engineers in the subject. A careful examination of these publications shows that they tend to fall into one of the two categories. The first is that of practical design direction in which methods for analyzing specific stability problems related to some specific structural typologies are developed. The research works are restricted to determining the critical load, considering that it is sufficient to know the limits of stability range. These studies are invaluable since their aim is to provide solutions to practical problems, to supply the designer with data useful for design and prepare norms, specifications and codes. The second direction is that of theoretical studies, aiming at a mathematical modeling of the instability problems, for a better understanding of the phenomena. In these studies, special emphasis is placed on the behavior of structures after the loss of stability in the post-critical range. This approach is less familiar to designers as its results have not yet become part of current structural design practice.

The study of structural analysis and design is a central subject in civil, aeronautical, and mechanical engineering. This book presents a modern and unified introduction to structural analysis, with a strong emphasis on how structures actually behave. The unifying theme is the application of energy methods, developed without the formal mathematics of the calculus of variations. The energy approach makes it possible to articulate the logical relationship between equilibrium and compatibility; emphasize the unity of structural analysis, particularly for indeterminate structures; and identify the roles of idealization and discretization in structural modeling. Thus, energy methods also serve as a prelude to the main ideas behind modern computational approaches to structural analysis and design. As an aid to upper-level undergraduate students in mastering this material, the text includes numerous worked examples, as well as homework problems.

When a structure is put under an increasing compressive load, it becomes unstable and buckling occurs. Buckling is a particularly significant concern in designing shell structures such as aircraft, automobiles, ships, or bridges. This book discusses stability analysis and buckling problems and offers practical tools for dealing with uncertainties that exist in real systems. The techniques are based on two complementary theories which are developed in the text. First, the probabilistic theory of stability is presented, with particular emphasis on reliability. Both theoretical and computational issues are discussed. Secondly, the authors present the alternative to probability based on the notion of 'anti-optimization', a theory that is valid when the necessary information for probabilistic analysis is absent, that is, when only scant data are available. Design engineers, researchers, and graduate students in aerospace, mechanical, marine, and civil engineering who are concerned with issues of structural integrity will find this book a useful reference source.
