Recent advances in adhesive technology have led to a rapid growth in the use of adhesives in load-bearing joints in civil engineering applications such as buildings and bridges. In many cases, the use of adhesives can prove more convenient, less expensive, stronger, and more durable than traditional methods of joining. This book provides for a complete and clear introduction to the use of adhesives to form load-bearing joints in bridges, civil engineering and building structures. The first part of this book addresses the crucial factors involved in the formation of a successful adhesive joint, including adhesive selection, surface preparation, joint design, fabrication and protection from the environment. The second part of the book describes the growing uses of adhesives to repair and strengthen existing structures, in addition to describing their use in new constructions and applications that are now being developed for the future. The connection between the two parts of the book is brought out wherever possible so that the links between theory and practice are emphasized. The book gives the reader all the information required to fully exploit the economic and technical advantages of adhesives over conventional methods. Professional civil and structural engineers in higher education and industry will find this book an invaluable source of information on a technology of increasing importance.

This comprehensive treatise covers in detail practical methods of analysis as well as advanced mathematical models for structures highly sensitive to creep and shrinkage. Effective computational algorithms for century-long creep effects in structures, moisture diffusion and high temperature effects are presented. The main design codes and recommendations (including RILEM B3 and B4) are critically compared. Statistical uncertainty of century-long predictions is analyzed and its reduction by extrapolation is discussed, with emphasis on updating based on short-time tests and on long-term measurements on existing structures. Testing methods and the statistics of large randomly collected databases are critically appraised and improvements of predictions of multi-decade relaxation of prestressing steel, cyclic creep in bridges, cracking damage, etc., are demonstrated. Important research directions, such as nanomechanical and probabilistic modeling, are identified, and the need for separating the long-lasting autogenous shrinkage of modern concretes from the creep and drying shrinkage data and introducing it into practical prediction models is emphasized. All the results are derived mathematically and justified as much as possible by extensive test data. The theoretical background in linear viscoelasticity with aging is covered in detail. The didactic style makes the book suitable as a textbook. Everything is properly explained, step by step, with a wealth of application examples as well as simple illustrations of the basic phenomena which could alternate as homeworks or exams. The book is of interest to practicing engineers, researchers, educators and graduate students.

The world is beginning to feel the crunch of depleting conventional energy sources and these desperate times call for exploring newer vistas in terms of alternative sources of energy. The construction sector is expected to require a major overhaul involving strategic advancements in the utilization of green energy given the rapid urban growth. A number of policy initiatives to mainstream energy efficiency are in place in most countries that are expected to accelerate energy efficiency and sustainability in buildings. Streamlining the green building movement requires coordinated monitoring and intelligent control of a building's vital functions. This can be achieved through building management systems (BMS) involving the integration of structures, systems, services, and management. Green building movements should examine the potential of power generation from urban, municipal, and industrial wastes. Equitable distribution of water resources should be carefully planned-monsoon-dominated countries should adopt efficient rain-water harvesting measures to provide clean water to thirsty nations. These overarching concepts are well woven into themed chapters in Green Structures: Energy Efficient Buildings. Easily comprehensible to undergraduates in civil, structural, and environmental engineering; graduate students and researchers; town planners; and architects worldwide, the content of this book not only comes from courses on energy efficient buildings taught by the authors, but also from new and original research. This definitive resource has an enduring appeal for all those concerned with green structures.

Construction Management is a wide ranging discipline, but ultimately it is a demanding, hands-on discipline concerned with the management of people, plant and materials, all mobilised to complete a building project safely, on time, on budget and to the client s satisfaction. Management of Construction Projects is a highly illustrated series of case studies based on seven live construction management projects, demonstrating the very practical nature of managing projects. The detailed case studies cover a variety of construction projects, varying in value from GBP1million to GBP117 million, including a major inner city office block, a portal framed factory unit, a university refurbishment project, a superstore & car park and a new school building. The case studies emphasise detailed on site management procedures and identify a predominantly functional approach to managing projects. A number of related chapters covering practical and theoretical aspects of construction management support and illustrate the individual case studies. With a strong emphasis on the practical nature of the subject, Management of Construction Projects is an ideal introduction to the subject for all students on construction and related degree and diploma programmes. It will be of particular interest to students preparing for the CIOB EPA programme and the new NVQ courses at level 4 and 5 in construction management.

This monograph presents the results of theoretical and experi mental studies as well as the design and construction features of structural systems with rational parameters. It starts by outlining issues around the topological (bionic) optimization of structures and suggests ways to address them. The computational compiler underlying the proposed approach incorporates the finite element method and the adaptive evolution method. Thus, this volume outlines new energy principles that speak in favour of the proposed methodology. The solutions presented here were verified experi mentally using new methods for testing structures for the effects of force and temperature. The theoretical studies also provide a methodology for assessing the technical condition, durability, and service life of structures. The book sets out the specific features of the design and construction of systems produced using the proposed approach. New reinforced- concrete, steel-reinforced-concrete, and steel systems, as well as manufacturing and construction technologies, are described in detail. Designs for buildings, structures, and pedestrian and road bridges are shown. Examples of erected structures are cited, and issues with regard to designing large-span suspension systems with rational parameters are considered. The manual is intended for engineers and researchers dealing with creating, studying, designing, and erecting engineering structures and systems thereof; structural- and civil-engineering teachers and students may also find it handy.

The design of structures in general, and prestressed concrete structures in particular, requires considerably more information than is contained in building codes. A sound understanding of structural behaviour at all stages of loading is essential. This textbook presents a detailed description and explanation of the behaviour of prestressed concrete members and structures both at service loads and at ultimate loads and, in doing so, provide a comprehensive and up-to-date guide to structural design. Much of the text is based on first principles and relies only on the principles of mechanics and the properties of concrete and steel, with numerous worked examples. However, where the design requirements are code specific, this book refers to the provisions of Eurocode 2: Design of Concrete Structures and, where possible, the notation is the same as in Eurocode 2. A parallel volume is written to the Australian Standard for Concrete Structures AS3600-2009. The text runs from an introduction to the fundamentals to in-depth treatments of more advanced topics in modern prestressed concrete structures. It suits senior undergraduate and graduate students and also practising engineers who want comprehensive introduction to the design of prestressed concrete structures. It retains the clear and concise explanations and the easy-to-read style of the first edition, but the content has been extensively re-organised and considerably expanded and updated. New chapters cover design procedures, actions and loads; prestressing systems and construction requirements; connections and detailing; and design concepts for prestressed concrete bridges. The topic of serviceability is developed extensively throughout. All the authors have been researching and teaching the behaviour and design of prestressed concrete structures for over thirty-five years and the proposed new edition of the book reflects this wealth of experience. The work has also gained much from Professor Gilbert active and long-time involvement in the development of standards for concrete buildings and concrete bridges.

This book lays the foundation of knowledge that will allow a better understanding of nonlinear phenomena that occur in structural dynamics. This work is intended for graduate engineering students who want to expand their knowledge on the dynamic behavior of structures, specifically in the nonlinear field, by presenting the basis of dynamic balance in non-linear behavior structures due to the material and kinematics mechanical effects. Particularly, this publication shows the solution of the equation of dynamic equilibrium for structure with nonlinear time-independent materials (plasticity, damage and frequencies evolution), as well as those time dependent non-linear behavior materials (viscoelasticity and viscoplasticity). The convergence conditions for the non-linear dynamic structure solution are studied and the theoretical concepts and its programming algorithms are presented.

This comprehensive textbook combines classical and matrix-based methods of structural analysis and develops them concurrently. It is widely used by civil and structural engineering lecturers and students because of its clear and thorough style and content.

The book's conclusions will facilitate the practical application of this new fastening technology.

This text addresses the modeling of vibrating systems with the perspective of finding the model of minimum complexity which accounts for the physics of the phenomena at play. The first half of the book (Ch.1-6) deals with the dynamics of discrete and continuous mechanical systems; the classical approach emphasizes the use of Lagrange's equations. The second half of the book (Ch.7-12) deals with more advanced topics, rarely encountered in the existing literature: seismic excitation, random vibration (including fatigue), rotor dynamics, vibration isolation and dynamic vibration absorbers; the final chapter is an introduction to active control of vibrations. The first part of this text may be used as a one semester course for 3rd year students in Mechanical, Aerospace or Civil Engineering. The second part of the text is intended for graduate classes. A set of problems is provided at the end of every chapter. The author has a 35 years experience in various aspects of Structural dynamics, both in industry (nuclear and aerospace) and in academia; he was one of the pioneers in the field of active structures. He is the author of several books on random vibration, active structures and structural control.

This book comprises the proceedings of the Annual Conference of the Canadian Society of Civil Engineering 2021.

This book presents a modern continuum mechanics and mathematical framework to study shell physical behaviors, and to formulate and evaluate finite element procedures. With a view towards the synergy that results from physical and mathematical understanding, the book focuses on the fundamentals of shell theories, their mathematical bases and finite element discretizations. The complexity of the physical behaviors of shells is analysed, and the difficulties to obtain uniformly optimal finite element procedures are identified and studied. Some modern finite element methods are presented for linear and nonlinear analyses. In this Second Edition the authors give new developments in the field and - to make the book more complete - more explanations throughout the text, an enlarged section on general variational formulations and new sections on 3D-shell models, dynamic analyses, and triangular elements. The analysis of shells represents one of the most challenging fields in all of mechanics, and encompasses various fundamental and generally applicable components. Specifically, the material presented in this book regarding geometric descriptions, tensors and mixed variational formulations is fundamental and widely applicable also in other areas of mechanics.

The daily work of engineers, for preliminary design and to check plausibility, would be inconceivable without them: design aids for reinforced concrete elements in the form of diagrams and tables. Now newly revised to cover Eurocode 2.

Matrix analysis of structures is a vital subject to every structural analyst, whether working in aero-astro, civil, or mechanical engineering. It provides a comprehensive approach to the analysis of a wide variety of structural types, and therefore offers a major advantage over traditional metho~ which often differ for each type of structure. The matrix approach also provides an efficient means of describing various steps in the analysis and is easily programmed for digital computers. Use of matrices is natural when performing calculations with a digital computer, because matrices permit large groups of numbers to be manipulated in a simple and effective manner. This book, now in its third edition, was written for both college students and engineers in industry. It serves as a textbook for courses at either the senior or first-year graduate level, and it also provides a permanent reference for practicing engineers. The book explains both the theory and the practical implementation of matrix methods of structural analysis. Emphasis is placed on developing a physical understanding of the theory and the ability to use computer programs for performing structural calculations.

This book describes the development of an innovative solution for electrified roadway pavements based on engineered cementitious composites, which are exhibiting an extreme tensile strain capacity that is much higher than conventional concrete. This enables the pavement to work without steel reinforcement and to embed a dynamic wireless power transfer technology for charging electric vehicles. At first, the book presents a modified performance-driven design approach to improve the composites to achieve the optimum pavement design in terms of functional and structural performance. It shows that the modified composites can be used to fulfil the safety and comfort factors without neglecting the characteristics of conventional ones. Further, 3D finite element and fluid dynamics models are used to analyse the pavement properties. The validated models can predict the functional performance, including skid resistance, surface water drainage, and noise. In the remaining part of the thesis, an environmentally-friendly photocatalytic function for pavement made of engineered cementitious composites is investigated. In turn, a multi-criteria design analysis is proposed to identify the optimum functional performance of the pavements. All in all, this book reports on a comprehensive approach to design, analyse and optimize engineered cementitious composites for electrified road pavement application. A special emphasis is given on applications in Singapore and other tropical megacities.

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 book covers the essentials of developments in the area of plate structures and presents them so that the readers can obtain a quick understanding and overview of the subject. Several theoretical models are employed for their analysis and design starting from the classical thin plate theory to alternatives obtained by incorporation of appropriate complicating effects or by using fundamentally different assumptions. The book includes pedagogical features like end-of-chapter exercises and worked examples to help students in self-learning. The book is extremely useful for the senior undergraduate and postgraduate students of aerospace engineering and mechanical engineering.

Since the firm's founding twenty-five years ago, AKT II have forged an international practice that unifies the cultures and disciplines of architecture and structural engineering. This book is an engine for critical reflection on the scope, potential, and limits of what they have come to define as design engineering. Structured into five discursive domains-scale, variability, attitude, reverse engineering, and the craftsmanship of engineering-the book presents a robust selection of the firm's endeavours, which together demonstrate a vast range of encounters and processes in design. Common among them is a desire to understand and reshape the boundaries of the discipline of structural engineering, along with its links to fields such as philosophy, computer science, and geography. Interlaced with the projects, texts by contributors from varying fields engage the theoretical discussions and social conditions that bind contemporary practice. Matters of Engineering Design: AKT II balances structural concerns that require an equilibrium of internal and external forces, a clear understanding of boundary conditions, and knowledge of the properties of material with the overarching challenges that society faces today, including advances in technology, changing economic orders, and ecological responsibility. With contributions by William Baker, David Basulto, Hanif Kara, Jayne Kelley, Priya Khanchandani, Adrian Lahoud, Lesley Lokko, Ibrahim Mahama, Stephen Parnell, Vicky Richardson, and Ellis Woodman.

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.
