This book introduces practising engineers and post-graduate students to modern approaches to seismic design, with a particular focus on reinforced concrete structures, earthquake resistant design of new buildings and assessment, repair and strengthening of existing buildings. Fundamentals of engineering seismlogy are covered in the first part, including structural dynamics, calculation of structural response, energy considerations, structural configuration, static and dynamic analysis of structures under seismic actions, represented by equivalent lateral loads, or by elastic and inelastic spectra including the Eurocode 8 spectrum. The second part explains the earthquake-related properties of reinforced concrete materials, and seismic behaviour of structural members. Eurocode 8 design provisions for each type of member are presented in detail, as well as a fully worked design application. It concludes with a discussion of methods for assessing seismic performance of structures, and several case studies involving concrete buildings with frames and structural walls with and without masonry infill panels. Seismic pathology of concrete structures, assessment of seismic capacity of exist

The interaction between engineering and the law is undergoing dramatic changes. Product liability, laws have been introduced in Japan, patent claims over living organisms have been made in bioengineering and the differing national laws of copyright protection and liability are in the process of harmonisation, especially in the European Union. The pace and complexity of these changes make it essential for technologists, lawyers, engineers and insurance experts to establish a common basis for understanding, co-operation and exchange of expertise. The recently founded International Society for Technology, Law and Insurance aims to foster such co-operation. This volume features 46 selected contributions which address various topical issues and the law. The most important issues relate to engineering risks, quality assurance and assessment and legal implications assiciated with them. Recent failure cases are explained and the technical, legal and insurance-related issues discussed in detail.

To facilitate a deeper understanding of tensegrity structures, this book focuses on their two key design problems: self-equilibrium analysis and stability investigation. In particular, high symmetry properties of the structures are extensively utilized. Conditions for self-equilibrium as well as super-stability of tensegrity structures are presented in detail. An analytical method and an efficient numerical method are given for self-equilibrium analysis of tensegrity structures: the analytical method deals with symmetric structures and the numerical method guarantees super-stability. Utilizing group representation theory, the text further provides analytical super-stability conditions for the structures that are of dihedral as well as tetrahedral symmetry. This book not only serves as a reference for engineers and scientists but is also a useful source for upper-level undergraduate and graduate students. Keeping this objective in mind, the presentation of the book is self-contained and detailed, with an abundance of figures and examples.

This book is a collection of papers presented in the NDT Conference held on February 20-23, 1996 at San Diego, California. The conference provided an opportunity to share experience and provide additional input to the Federal Highway Administration.

This work consists of two parts: engineering seismology and earthquake-resistant design. Special attention is placed on bridging the gap between these two disciplines. The fundamentals of seismology, earthquake engineering and random processes are introduced. This is followed by a chapter describing the earthquake intensity, ground motions, and its damage effects. In ensuing chapters concerning the earthquake-resistant design, both fundamental theories and new research problems and future directions are presented, including methods for foundation design and structural experiments. Finally, in the last chapter on engineering applications, seismic risk and its damaging effects, seismic zonation and features of earthquake-resistant design of different types of structures and design standards are introduced.

This is the first fully comprehensive survey and analysis of masted structures and covers examples that have evolved during the past three decades. Masted Structures are one of the most interesting developments in post-war architecture resulting from a combination of technology, structural engineering theory and a collaboration between architects and engineers. This is an essential guide for architects to the structural and constructional implications of masted forms in relation to space enclosure, patterns of loading and use of differing materials and techniques. This useful volume will enable architects and engineers to understand the origins, development and nature of masted structures and will provide a stimulating basis for future design.

In the past ten years there was a worldwide trend towards increased use of Tunnel Boring Machines (TBM's). This trend covers a broad variety of applications ranging both from small diameters for sewers and other utilities to large diameters for double track railway and even three-lane highway tunnels. The response to this has been the development of both hard rock machines in the direction for application in soft ground, and soft ground TBM's to be used in soft rock. Parallel to the technical development of TBM's towards applications for longer tunnels, running through changing geological conditions, there are needs for the development of lining methods. 'TBM Tunnel Trends' an international lecture serie collection, aims to present the latest scientific and practical state of the art of TBM tunnelling, taking into consideration interactions between machinery and lining. 26 international highly recognized papers.

The integration of photovoltaics (PV) into buildings goes beyond energy saving by providing a clean and elegant way of actually generating electricity. There are already numerous successful examples and rapid technological improvements promise expansion of PV's present niche market to that of a major energy provider of the 21st century. This handbook is the outcome of a five year programme which took place under the auspices of the International Energy Agency. Architects and solar experts from 13 countries addressed the wide range of engineering and architectural issues involved in the successful integration of PV into buildings. It demonstrates how to maximise the overall solar contribution to the building; integrate PV effectively with the building structure; clarify the relationship of PV with other elements of the building's energy system; optimise the system economics. It forms a thorough design guide that covers all aspects if the subject and will enable all building designers, engineers and property owners to make the integration of PV into buildings an architecturally appealing and energetically effective option.

This text discusses factors such as mast overload, capacity of drawworks, and deviation in the hole to be drilled and the strata to be drilled. An omnibus approach to drilling techniques and problems is adopted.

Invited international contributions to this exciting new research field are included in this volume. It contains the specially selected papers from 45 key specialists given at the Symposium held under the auspices of the prestigious International Union of Theoretical and Applied Mechanics at Turin in October 1994.

Tunnelling is a high risk business. Success depends crucially on the nature of the ground through which the tunnel is being driven. The cost of a thorough site investigation is usually only a small fraction of the cost of the construction work but this crucial phase of a project is often given too low a priority. This text provides a review of tunnelling contracts, particularly those for sewerage and drainage tunnels. It reviews site investigation methods, contract preparation and tender evaluation, tunnel costruction, claims and records, and the post-construction phase. Examples of good and bad practice of site investigation and other aspects of tunnelling are given, and the text is supported by over 500 references. Supplementary information in the second part of the book expands on particular aspects such as ground vibration and noise. Among other topics covered are quality assurance, rock properties and testing, pollution, permeability and dewatering.

A state-of-the-art report prepared by RILEM Technical Committee 116-PCD. At present, durability of concrete is controlled by specifying the materials to be used, the methods of mixing, placing, curing and so on. This approach is often unsatisfactory and it is a common objective of concrete researchers and engineers to develop performance criteria which allow the potential durability of a particular concrete mix or structure to be estimated. However, the complexity of concrete as a material and the difficulty of developing consistent and reliable test methods has meant that progress has been slow. International interest in the subject is growing strongly with the development of international standards and so this book is very timely in giving an authoritative, international review of the subject. It will set the scene for the next few years as a key source of information and advice.

This book provides a new framework for analysis of slope nonlinear stochastic seismic dynamic response based on the new theoretical tool of stochastic dynamics. The coupling effects of uncertainty of geological parameters, strong dynamic nonlinearity, and randomness of ground motion are considered in the process of the seismic dynamic stability assessment of slope. In this book, an intensity frequency non-stationary stochastic ground motion model based on time-domain stochastic process description is preliminarily established to characterize the randomness of earthquakes. The spatial distribution random field model of geotechnical parameters is established to describe the time-space variability of geotechnical parameters. Based on the basic theory of stochastic dynamics, the seismic stability performance evaluation method of slope is established. The slope seismic dynamic model test based on large complex shaking table is performed to verify and modify the proposed framework and method. This book sheds new light on the development of nonlinear seismic stochastic dynamics and seismic design of slope engineering.

This book addresses problems in structural dynamics and control encountered in such applications as: aerospace structures, robotics, earthquake-damage prevention, and active noise suppression. The rapid developments of new technologies and computer power have made it possible to formulate and solve engineering problems that seemed unapproachable only a few years ago. The treatment combines concepts from control engineering (such as system norms and controllability) and structural engineering (such as modal properties and modal models), thereby both revealing new structural properties as well as giving new insights into well-known laws. The techniques discussed will make it easier for structural engineers to design control systems and for control engineers to deal with structural dynamics. The discussion begins by defining flexible structures and structural models, using such examples as the international space station and the antennas of NASA's deep-space network. The book then turns to controllability and observability; properties of system norms (Häsubinfinityü, Häsub2ü, and Hankel); and model reduction in terms of these norms. A discussion of sensor and actuator location follows: selecting these is rarely an easy task. The concluding chapters discuss the design of dissipative LQG and Häsubinfinityü controllers. Matlab codes for many of the procedures and methods discussed in the book are included.

This book deals with the new developments and application of the geometric method to the nonlinear stability problem for thin non-elastic shells. A.V. Pogorelov (Harkov, Ukraine) was the first to provide in his monographs the geometric construction of the deformed shell surface in a post-critical stage and deriving explicityly the asymptotic formulas for the upper and lower critical loads. The geometric method by Pogorelov is one of the most importanty analytical methods developed during the last century. Its power consists in its ability to provide a clear geometric picture of the post critical form of a deformed shell surface, successfully applied to a direct variational approach to the nonlinear shell stability problems. Until now, most of Pogorelov's monographs were written in Russian, which limited the diffusion of his ideas among the international scientific community. The present book is intended to assist and encourage the researchers in this field to apply the geometric method and the related results to everyday engineering practice. Further developments of the geometric method are carried out in this book and are directed to stability of thin shells in the case of elastic anisotropy, elastic anisotropy with linear memory and elasto-plastic properties of the shell material. This book is intended to serve both as a textbook for post-graduate students in structural engineering and applied mathematics, and as a revference monograph for academic and industrial researchers.

Post-tensioning is the most versatile form of pre stressing, a technique which enables engineers to make the most effective use of the material properties of concrete, and so to design structural elements which are strong, slender and efficient. Design in post-tensioned concrete is not difficult and, if done properly, can contribute significantly to the economy and the aesthetic qualities of a building. Post-tensioned floors have found widespread use in office buildings and car park structures, and are also frequently employed in warehouses and public buildings. However, in spite of this, most prestressed concrete texts devote comparatively little attention to floors, concentrating instead on beam elements. This book answers the need for a comprehensive treatment of post-tensioned floor design.

Derived from the invited IUTAM Symposium in September 1993, this volume's contributions discuss recent advances in fracture mechanics, studies of concrete, rock, ceramics and other brittle disordered materials at micro and structural levels. It draws together research and new applications in continuum, damage and fracture mechanics approaches.

In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase ineconomic incentives to the user. Because theoperating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to beshared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children'sbookofdefinitions wrote,"AHole...Is to Dig." But thisstatement is not necessarily true. Today, a hole could be to bore. Trenchless technology is not new. But it certainly has become the buzzword of the construction industry and it appears that it will have a growing impact in the way contractors, utilities, and others install new facilities. Methods to bore horizontal holes were practiced as early as the 18005, but this technology has greatly changed. Today's tools include sophisticated drilling methods, state-of the-art power systems, and electronic guidance techniques. These tools can bore faster, safer, and more accurately, and in many instances more economically, than open-cllt methods. Technology has played an important role in these advances, but economics has become the driving force in making these systems popular."

Ferrocement is a versatile, construction material, with applications in low cost housing, rehabilitation, strengthening and repair of structures, especially in the developing world. The material can also be used in more advanced constructions for thin shell structures. This book forms the proceedings of the Fifth International Symposium on Ferrocement. It presents the latest developments in research and application of the material and should serve as a useful reference for all those interested in the material. This includes both researchers in all parts of the world, but also those responsible for low cost housing and construction in developing countries, in South America, Africa and the Far East. This book should be of interest to researchers concerned with building materials, government and international agencies involved with low cost housing, and repair specialists, consultants, contractors and material suppliers.
