Problems in nonlinear structural dynamics and critical excitation with elastic-plastic structures are typically addressed using time-history response analysis, which requires multiple repetitions and advanced computing. This alternative approach transforms ground motion into impulses and takes an energy balance approach. This book is accessible to undergraduates, being based on the energy balance law and the concepts of kinetic and strain energies, and it can be used by practitioners for building and structural design. This presentation starts with simple models that explain the essential features and extends in a step-by-step manner to more complicated models and phenomena.

Before structural mechanics became the common language of structural engineers, buildings were built based on observed behavior, with every new solution incurring high levels of risk. Today, the pendulum has swung in the other direction. The web of structural mechanics is so finely woven that it hides the role of experience in design, again leading to high levels of risk.

Understanding Structures brings the art and science of structures into the environment of a computer game. The book imparts a basic understanding of how buildings and bridges resist gravity, wind, and earthquake loads. Its interactive presentation of topics spans elementary concepts of force in trusses to bending of beams and the response of multistory, multi-bay frames.

Formulate Graphical and Quantitative Solutions with GOYA

The companion software, GOYA, runs easily on any java-enabled system. This interactive learning environment allows engineers to obtain quick and instructive graphical and quantitative solutions to many problems in structures.

Simulation is critical to the design and construction of safe structures. Using GOYA and the tools within Understanding Structures, engineers can enhance their overall understanding of structure response as well as expedite the process of safe structure design.

In a straightforward style, this book presents a detailed overview of 20 cases of famous and other highly interesting bridge collapses over the last two centuries. Every case is illustrated and described in detail and the failure analyses made are supported by well-known explanations and, in some cases, by new theories. The chronological order makes it easy to follow the gradual development in the use of different bridge types and the choice of construction material. The increase of knowledge and experience in the structural engineering discipline over the years is clearly observable, although every modern engineer will admit that both fatigue and buckling are very complex phenomena and that knowledge about them can increasingly profit from studying past bridge construction projects failures. Intended for consulting engineers (bridges, steel and metal structures) and for advanced-level and postgraduate students in structural and bridge engineering.

New Trends in Fracture Mechanics of Concrete contains Volume 1 of the Proceedings of the 6th International Conference on Fracture Mechanics of Concrete and Concrete Structures (FraMCoS-6, Catania, Italy, 17-22 June 2007). It is divided into four parts: (1) Theoretical and Numerical Methods in Fracture Mechanics of Concrete; (2) Experimental Methods in Fracture Mechanics of Concrete; (3) Constitutive Damage Modelling of Concrete; (4) Time Effects in the Damage and Fracture of Concrete. Over the last twenty years, many theoretical, numerical and experimental methods have evolved in the field of Fracture Mechanics of Concrete. These have led to practical applications in reinforced-concrete design, assessment, monitoring and retrofitting, as well as innovative high-performance and durable cementitious materials. Although Fracture Mechanics of Concrete is now mature as a framework for defining and solving a variety of engineering problems, there is still much work to be done in improving previous theoretical and numerical models, and for re-interpreting established phenomena. In particular, there are new developments in the treatment of scale effects; the implementation of 3D-discretisation; and the combination of continuous and discontinuous models. Other areas of rapid progress are the development of innovative testing techniques; the proposal of non-local and anisotropic constitutive laws; the formulation of lattice and multiscale models, and the development of coupled multifield theories. The other two volumes comprising the Proceedings of the 6th International Conference on Fracture Mechanics of Concrete and Concrete Structures are Design, Assessment and Retrofitting of RC Structures; and High-Performance Concrete, Brick-Masonry and Environmental Aspects. The set presents a wealth of information, and will be useful to professional civil engineers, postgraduate students and researchers.

The book focuses on the recent innovations in computational techniques, material and digital fabrication technology that are revolutionizing the design, analysis and construction of surface structures. Powerful analysis tools now enable the accurate prediction of structural behaviour and manufacturing processes. Material innovations in the area of cementitious and other composites, glass, or smart materials, to just name a few, are challenging architects to find appropriate forms and applications. Digitally supported fabrication technology has taken a quantum leap since the time of the master shell builders 40 years ago, unfolding new potential to realize complex structural shapes in new and innovative ways. These innovations are presented in the context of an in-depth introduction to the fundamentals of surface structures providing the necessary knowledge for the successful design of shells and tensile systems in a broad variety of materials. Many of the principles are demonstrated using new material of some of the masterpieces in surface architecture. The book is structured into three parts. The first part familiarizes the reader with the topic of surface structures. It provides a historic overview and explains the underlying structural principles and traditional construction techniques. Part II introduces design methods, emphasizing recent developments in computational design and analysis that have greatly facilitated the design and construction of surface structures. Part III presents case studies demonstrating use of innovative and emerging materials.

Examining the fundamental differences between design and analysis, Robert Benaim explores the close relationship between aesthetic and technical creativity and the importance of the intuitive, more imaginative qualities of design that every designer should employ when designing a structure. Aiding designers of concrete bridges in developing an intuitive understanding of structural action, this book encourages innovation and the development of engineering architecture. Simple, relevant calculation techniques that should precede any detailed analysis are summarized. Construction methods used to build concrete bridge decks and substructures are detailed and direct guidance on the choice and the sizing of different types of concrete bridge deck is given. In addition guidance is provided on solving recurring difficult problems of detailed design and realistic examples of the design process are provided. This book enables concrete bridge designers to broaden their scope in design and provides an analysis of the necessary calculations and methods.

The book will be of interest to researchers, academics, students, software developers, and practical engineers across the field of geotechnics.

Design and Construction of Pavements and Rail Tracks - Geotechnical Aspects and Processed Materials is a compilation of selected contributions produced between 2002 and 2005 by the International Committee TC3 - Geotechnics of Pavements of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), a committee dedicated to gathering current knowledge of geotechnical aspects relating to pavements and rail tracks. The volume presents advanced procedures for laboratory and field materials characterization, including processed materials (non-conventional road construction materials), novel tests for field stiffness evaluation, a pre-standard for roller integrated continuous compaction control and new theories for evaluation of the long term performance of materials, including environmental aspects. These contributions represent the latest developments relating to the design, construction and long term performance of pavements, rail tracks and earth structures, with emphasis on the geotechnical and environmental background.

Tunnels have a high degree of risk that needs to be assessed and managed. Underground works intersect and interact with natural materials, incorporating their characteristics as structural components of their own stability. For this reason geotechnical risk analyses are implemented at all phases of tunnel construction, from design through to post-construction maintenance. Analysis of geotechnical risk involves a group of studies which lead to the identification and evaluation of the potential probability of error and the consequences of its occurrence. This volume considers construction and safety, financing and control, and exploration and maintenance. Eminent specialists discuss risk assessment and management, based both on advanced theoretical concepts and on practical experience. The book is of interest to a wide range of professionals involved in planning, construction and management of tunnels: entrepreneurs, designers, consultants and contractors.

This conference proceedings brings together the work of researchers and practising engineers concerned with computational modelling of complex concrete, reinforced concrete and prestressed concrete structures in engineering practice. The subjects considered include computational mechanics of concrete and other cementitious materials, including masonry. Advanced discretisation methods and microstructural aspects within multi-field and multi-scale settings are discussed, as well as modelling formulations and constitutive modelling frameworks and novel experimental programmes. The conference also considered the need for reliable, high-quality analysis and design of concrete structures in regard to safety-critical structures, with a view to adopting these in codes of practice or recommendations. The book is of special interest to researchers in computational mechanics, and industry experts in complex nonlinear simulations of concrete structures.

Although the use of composites has increased in many industrial, commercial, medical, and defense applications, there is a lack of technical literature that examines composites in conjunction with concrete construction. Fulfilling the need for a comprehensive, explicit guide, Reinforced Concrete Design with FRP Composites presents specific information necessary for designing concrete structures with fiber reinforced polymer (FRP) composites as a substitute for steel reinforcement and for using FRP fabrics to strengthen concrete members. In a reader-friendly, design-oriented manner, this book discusses the analysis, design, durability, and serviceability of concrete members reinforced with FRP. The authors first introduce the elements that constitute composites-the structural constituent and matrix-and discuss how composites are manufactured. Following an examination of the durability of FRP composites that contain fibers, such as glass, carbon, or aramid, the book illustrates how FRP external reinforcement systems (FRP-ER) can be used for enhancing the strength and stiffness of concrete structures using theory and design principles. The concluding chapter concentrates on serviceability aspects of concrete members internally reinforced with FRP. An excellent resource of design and construction practices, Reinforced Concrete Design with FRP Composites is a state-of-the-art reference on concrete members reinforced with FRP.

From abandoned structures that have long ceased to take you anywhere to today's feats of engineering, Bridges is a pictorial celebration of 150 suspension bridges, iron bridges, stone bridges, aqueducts, viaducts, railway bridges, footbridges and rope bridges. Organised in sections such as abandoned bridges, classic bridges and superstructures, the book contains an immense range of wooden, stone, iron, steel and concrete bridges. There are tiny village bridges and vast bridges, narrow bridges and motorway-wide bridges, bridges that act as dams and bridges that support buildings, covered bridges, famous bridges and little-known gems. From San Francisco's Golden Gate bridge to the 21st century Millau Viaduct in France - the tallest bridge in the world, from the Roman aqueduct in Segovia, Spain, to farmers still building bamboo bridges, the book draws examples from all over the world. Ranging from the Rocky Mountains to Siberia and Iran, a picture emerges of not only how new technologies have made it possible for bridges to be built, but also how bridges have themselves been catalysts for social change. And when they have been abandoned, such as in former gold rush towns, these bridges tell their own stories of how the world moves on. Presented in a landscape format and with 150 outstanding colour photographs, Bridges is a stunning collection of images.

Residual soils are found in many parts of the world. Like other soils, they are used extensively in construction, being built upon and used as construction materials. Residual soils are formed when the processes of rock weathering proceed at a faster rate than the transport processes by water, gravity and wind, whereby much of the resulting soils will remain in place. The soil typically retains many of the characteristics of the parent rock. In a tropical region, residual soil layers can be very thick, sometimes extending for hundred of meters before reaching unweathered rock. This book has gathered state-of-the-art knowledge from a number of experienced experts working in foundation engineering in tropical residual soils. Subjects covered are: geology and formation of residual soils, site investigations, characterization and selection of parameters for foundation design, design of shallow and deep foundations which include driven piles, drilled shafts and caissons, and special topics which include design of piles in marginally-stable river banks, micro piles, Augeo pile, pile load and NDT, foundation failures and remedial works, and pile supported embankment. The book also includes a country case study on engineering geology in relation to foundation engineering in Malaysia.

Following years of research, the first bored tunnel in soft soil in the Netherlands, the Tweede Heinenoord tunnel, was completed in 1998.

Modelling forms an implicit part of all engineering design but many engineers engage in modelling without consciously considering the nature, validity and consequences of the supporting assumptions. Derived from courses given to postgraduate and final year undergraduate MEng students, this book presents some of the models that form a part of the typical undergraduate geotechnical curriculum and describes some of the aspects of soil behaviour which contribute to the challenge of geotechnical modelling. Assuming a familiarity with basic soil mechanics and traditional methods of geotechnical design, this book is a valuable tool for students of geotechnical and structural and civil engineering as well as also being useful to practising engineers involved in the specification of numerical or physical geotechnical modelling.
