This book will be essential reading for civil and structural engineers, designers and researchers.

Ordinary concrete is strong in compression but weak in tension. Even reinforced concrete, where steel bars are used to take up the tension that the concrete cannot resist, is prone to cracking and corrosion under low loads. Prestressed concrete is highly resistant to stress, and is used as a building material for bridges, tanks, shell roofs, floors, buildings, containment vessels for nuclear power plants and offshore oil platforms. With a wide range of benefits such as crack control, low rates of corrosion, thinner slabs, fewer joints and increased span length; prestressed concrete is a stronger, safer, more economical and more sustainable building material. The introduction of the Eurocodes has necessitated a new approach to the design of prestressed concrete structures and this book provides a comprehensive practical guide for professionals through each stage of the design process. Each chapter focuses on a specific aspect of design Fully consistent with Eurocode 2, and the associated parts of Eurocodes 1 and 8 Examples of challenges often encountered in professional practice worked through in full Detailed coverage of post-tensioned structures Extensive coverage of design of flat slabs using the finite element method Examples of pre-tensioned and post-tensioned bridge design An introduction to earthquake resistant design using EC 8 Examining the design of whole structures as well as the design of sections through many fully worked numerical examples which allow the reader to follow each step of the design calculations, this book will be of great interest to practising engineers who need to become more familiar with the use of the Eurocodes for the design of prestressed concrete structures. It will also be of value to university students with an interest in the practical design of w

Tools to Safeguard New Buildings and Assess Existing Ones
Nonlinear analysis methods such as static pushover are globally considered a reliable tool for seismic and structural assessment. But the accuracy of seismic capacity estimates which can prevent catastrophic loss of life and astronomical damage repair costs depends on the use of the correct basic input parameters.

Seismic Design Aids for Nonlinear Analysis of Reinforced Concrete Structures simplifies the estimation of those vital parameters. Many design engineers make the relatively common mistake of using default properties of materials as input to nonlinear analyses without realizing that any minor variation in the nonlinear characteristics of constitutive materials, such as concrete and steel, could result in a solution error that leads to incorrect assessment or interpretation.

Streamlined Analysis Using a Mathematical Model
To achieve a more accurate pushover analysis and improve general performance-based design, this book reassesses some key inputs, including axial force-bending moment yield interaction, moment-curvature, and moment-rotation characteristics. It analyzes these boundaries using a detailed mathematical model of reinforced concrete sections based on international codes, and then proposes design curves and tables derived from the authors studies using a variety of nonlinear tools, computer programs, and software. The text reviews relevant literature and describes mathematical modeling, detailing numerical procedures step by step.

Including supplementary online material that can be used to compute any parameter, this reference delineates nonlinear properties of materials so that they can be used instantly for seismic analysis without having to solve cumbersome equations.

The spectacular structures of today, such as large suspension bridges, are the result of scientific principles established during the new iron age of the nineteenth century. The book is concerned with a detailed and critical account of the development and application of those principles (including statics and elasticity) by people of remarkable talent in applied mathematics and engineering. They were, of course, mainly motivated by the demands of the railway, construction boom. Among the outstanding examples chosen by the author is Robert Stephenson’s use of novel principles for the design and erection of the Britannia tubular iron bridge over the Menai Straits. A History of the Theory of Structures in the Nineteenth Century is a uniquely comprehensive account of a century of the development of the theory; an account which skilfully blends the personalities and the great works and which is enlivened by little-known accounts of friendship and controversy.

In dealing with extreme loads on structures, simple approximations of key variables can indicate if there is a threat of collapse. The ability to determine such variables early on strongly impacts the decisions about the engineering approach to adopt. Formulas for Mechanical and Structural Shock and Impact is a self-contained and concise presentation of formulas and methodology you can use to determine dynamic response to shock loads, to help you decide on the optimal design. This book offers insight into how objects and structures respond to sudden, strong-and generally short-impulses. In our computer-oriented environment, in which structural programs are used for most large analytical tasks, engineers can still benefit from certain manual calculations and analytical methods to quickly assess the situation at hand. Exploring a range of mechanical and civil engineering applications, the text enables engineers to manually calculate what happens to structures and objects when pushed, pulled, jerked, or blasted by providing ready access to formulas required for advanced problem solving. It describes relatively simple methods of dealing with many design situations, in which simple spreadsheets or MathCad are sometimes employed. These scenarios may include: Determination of preliminary figures on the anticipated dynamic response of a system that is in an early stage of design and for which a full-scale computation is not practical Preparations for physical testing or for large-scale calculations, during which a dynamic model is generated Indirect verification of computer-generated results, to explain questionable results or guard against hidden errors Structural safety can be facilitated through the use of simple approximate solutions early in the design process, often eliminating the need for complicated and more involved solutions later. This book is a valuable companion for modern

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.

Many important advances in designing modern structures have occurred over the last several years.

It is an ideal introduction for newcomers to the field as well as a perfect review and quick-reference guide for seasoned engineers.

Modern hydraulic binders can be used effectively with Portland cement and supplementary cementitious materials to produce durable concrete. They also provide a means of recycling by-products from other industries and of decreasing the emission of greenhouse gases.
The first binders were discovered in ancient times when it was observed that new pozzolans mixed with lime could harden under water; and in the middle of the nineteen century the first artificial hydraulic binder, Portland cement, was discovered. By modifying the four basic oxides in the limestone and clay mix used in the production of Portland cement it is possible to modify significantly the practical properties of the clinker, and consequently the performance of the fresh and hardened concrete in which it is used.
Chemical admixtures can be used to disperse cement particles without the use of extra water, and so make concrete which is highly resistant to penetration by aggressive agents and of high durability and strength. Supplementary cementitious materials or fillers can be mixed with Portland cement to produce modern hydraulic binders and improve the ecological performance of concrete. The hydration process of a modern hydraulic binder is becoming quite complex because it involves the chemical reactivity of Portland cement clinker, of supplementary cementitious materials and of different types of admixtures. This has already resulted in great technological achievements such as high-performance concrete, self leveling concrete, confined concrete, high-performance roller compacted concrete, fiber reinforced concrete, and reactive powder concrete.

Cathodic protection of reinforced concrete structures is a technique for rescuing corrosion damaged structures and, in certain instances, preventing them from corroding in the first place, and its use is growing. This book is for specialist contractors, large consultants and owners of corrosion damaged structures, and looks at international experience with this technique. It examines why corrosion is occurring, the differences in the application of CP with the stark dichotomy in its success and failure, and finally ways in which its performance can be improved on future installations. Information is valuable, as the success or failure of the CP system has a marked effect on the service life of the structure.

A typical subsystem found in almost all aircraft and space vehicles consists of beam, plate and/or shell elements attached to each other in a rigid or flexible manner. Due to limitations on their weights, the elements themselves must be highly flexible, and due to limitations on their initial configuration (i.e., before deployment), those aggregates often have to contain several links so that the substructure may be unfolded or telescoped once it is deployed. The defining philosophy of this monograph is that in order to understand completely the dynamic response of such a complex elastic structure, it is not sufficient to consider only its global motion but also necessary to take into account the flexibility of individual elements and the interaction and transmission of elastic effects such as bending, torsion, and axial deformations at junctions where members are connected to each other. Therefore, the purposes of this monograph are: to derive distributed parameter models of the transient behavior of some or all of the state and interval variables which describe the dynamic response of multiple-link flexible structures such as trusses, frames, robot arms, solar panels, antennae and deformable mirrors, based on the principles of continuum mechanics and under reasonable constraints on the geometry of the admissible deformations; to provide rigorous mathematical analyses of the resulting models; and to develop control theoretic properties of multiple-link flexible structures based on the control theoretic properties of the models. The modelling and analysis of these complicated and realistic structural configurations should be of interest to a diverse group of applied mathematicians, structural, aeronautical, aerospace, and mechanical engineers and to advanced graduate students working on such problems.

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 behavior of elastic structures lead to a discussion of plastic behavior, and a final chapter indicates that there are still problems needing solution.

Elastic shells are pervasive in everyday life. Examples of these thin-walled structures range from automobile hoods to basketballs, veins and arteries, and soft drink cans. This book explains shell theory, with numerous examples and applications. This second edition not only brings all the material of the first edition entirely up to date; it also adds two entirely new chapters on general shell theory and general membrane theory. Aerospace, mechanical, and civil engineers, as well as applied mathematicians, will find this book a clearly written and thorough information source on shell theory.

Elastic structures, conceived as slender bodies able to transmit loads, have been studied by scientists and engineers for centuries. By the seventeenth century several useful theories of elastic structures had emerged, with applications to civil and mechanical engineering problems. In recent years improved mathematical tools have extended applications into new areas such as geomechanics and biomechanics. This book, first published in 1998, offers a critically filtered collection of the most significant theories dealing with elastic slender bodies. It includes mathematical models involving elastic structures, which are used to solve practical problems with particular emphasis on nonlinear problems. This collection of interesting and important problems in elastic structures will appeal to a broad range of scientists, engineers and graduate students working in the area of structural mechanics.

The accelerated, and often uncontrolled, growth of the cities has contributed to the ecological transformation of their immediate surroundings. Factors contributing to the urban vulnerability include: lowering or rising of the water table, subsidence, loss of bearing capacity of soil foundations and instability of slopes. Recent catastrophic earthquakes highlight the poor understanding by decision makers of seismic related risk, as well as the tendency of some builders to use the cheapest designs and construction materials to increase short-term economic returns on their investment.

Losses from earthquakes will continue to increase if we do not shift towards proactive solution. Disaster reduction is both an issue for consideration in the sustainable development agenda and a cross-cutting issue relating to the social, economic, environmental and humanitarian sectors. As location is the key factor, which determines the level of risk associated with a hazard, land-use plans and mapping should be used as tools to identify the most suitable usage for vulnerable areas.

The present volume contains a total of 23 papers centred on the research area of Seismic Assessment and Rehabilitation of Existing Buildings. This subject also forms the core of Project SfP977231, sponsored by the NATO Science for Peace Office and supported by the Scientific and Technical Research Council of Turkey [ TUBIT AK ]. Most of these papers were presented by the authors at a NATO Science for Peace Workshop held in Izmir on 13 - 14 May, 2003 and reflect a part of their latest work conducted within the general confines of the title of the NATO Project. Middle East Technical University, Ankara, Turkey serves as the hub of Project SfP977231 and coordinates research under the project with universities within Turkey, e. g. Istanbul Technical University and Kocaeli University, and with partner institutions in Greece and the Former Yugoslav Republic of Macedonia: A few articles have also been contributed by invited experts, who are all noted researchers in the field. Altogether, the contents of the volume deal with a vast array of problems in Seismic Assessment and Rehabilitation and cover a wide range of possible solutions, techniques and proposals. It is intended to touch upon many of these aspects separately below. Earthquakes constitute possibly the most widely spread and also the most feared of natural hazards. Recent earthquakes within the first six months of 2003, such as the Bingol Earthquake in Turkey and the Algerian earthquake, have caused both loss of life and severe damage to property.
