The pace of research and innovation has accelerated in the past three decades, reflecting the need to mitigate the risk of severe damage to interconnected infrastructures, and to facilitate the incorporation of high-speed computers and the internet. The respective papers focus on the design and analysis of concrete structures subjected to earthquakes, advance the state of knowledge in disaster mitigation, and address the safety of infrastructures in general.

Ulrich Häußler-Combe ... 354 pages - Publisher: Ernst&Sohn; (November, 2014) ... Language: English - ISBN-10: 3433030545 - ISBN-13: 978-3433030547

The book covers the application of numerical methods to reinforced concrete structures. To analyze reinforced concrete structures linear elastic theories are inadequate because of cracking, bond and the nonlinear and time dependent behavior of both concrete and reinforcement. These effects have to be considered for a realistic assessment of the behavior of reinforced concrete structures with respect to ultimate limit states and serviceability limit states. The book gives a compact review of finite element and other numerical methods. The key to these methods is through a proper description of material behavior. Thus, the book summarizes the essential material properties of concrete and reinforcement and their interaction through bond. These basics are applied to different structural types such as bars, beams, strut and tie models, plates, slabs and shells. This includes prestressing of structures, cracking, nonlinear stress?strain relations, creeping, shrinkage and temperature changes. Appropriate methods are developed for each structural type. Large displacement and dynamic problems are treated as well as short-term quasi-static problems and long-term transient problems like creep and shrinkage. Most problems are illustrated by examples which are solved by the program package ConFem, based on the freely available Python programming language. The ConFem source code together with the problem data is available under open source rules at concrete-fem.com. The author aims to demonstrate the potential and the limitations of numerical methods for simulation of reinforced concrete structures, addressing students, teachers, researchers and designing and checking engineers.

Concrete cellular structures are used extensively for residential buildings. In concept they are structurally simple but they require attention to detail to realise the benefi ts of ease of construction and economy. This guide is written for the structural engineer who has knowledge of building structures in general but who has limited or no experience of designing concrete cellular structures. It highlights areas that require close coordination between the structural and services engineers, the architect and importantly the system supplier. It also provides guidance on selecting an appropriate solution, sizing the structure and carrying out detailed design. Detailing considerations are explained, some of which have to be considered at the early stages of a project to achieve an effi cient building configuration.

This book offers a new calculation procedure of the structural behavior of grouped layout of silos, easy to use and with satisfactory responses. Groups of reinforced concrete silos are structures commonly used in the food industry, where it is usually necessary to separate the storage of different types and sources of grain. The grouped layout of silos has numerous benefits when compared with single-cell silos in which the emphasis is on creating further space for silage, normally referred to as interstice – a space formed between the edges of the group’s cells. This economic benefit, on the other hand, raises a structural problem for the designer of this type of building, which is to assess the magnitude of bending moments and hoop forces due to the structural continuity of the walls in the interstice region of the cells. Bending moments assume extreme values exactly when the interstice is loaded and the other cells in the group are empty. To develop the formulation of the proposed analysis models, a parametric study was carried out that allowed the adequate consideration of the variables involved.

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.

This book presents an analysis procedure for structures that are exposed to the lateral loads such as earthquake and wind. It includes the process for calculating and distributing the effective load into structural elements, as well as for calculating the displacements for different types of structures, e.g. reinforced concrete and steel framed structures. The book provides civil engineers with clear guidelines on how to perform seismic analysis for various building systems, and how to distribute the lateral load to the structural components. This book consists of 4 chapters: The first chapter offers an introduction, while Chapter 2 discusses moment resistance frame. The final two chapters explore shear wall frames and brace frames respectively. Each chapter follows the same structure, explaining step by step all the necessary algorithms, equations and procedures for calculating 1) loads, 2) the centre of mass, 3) stiffness of structures, 4) centre of stiffness, 5) lateral loading, 6) the distribution of lateral loads, and 7) the lateral displacement. Demonstrating the implementation of real building analysis, the book provides architectural drawings and structural plans at the beginning of each chapter.

Robin Whittle ... 148 pages - Publisher: CRC Press; (October, 2012) ... Language: English - ISBN-10: 0415567017 - ISBN-13: 978-0415567015

Some lessons are only learned from mistakes but, it’s much cheaper to learn from someone else’s mistakes than to have to do so from your own. Drawing on over fifty years of working with concrete structures, Robin Whittle examines the problems which he has seen occur and shows how they could have been avoided. The first and largest part of the book tells the stories of a number of cases where things have gone wrong with concrete structures. Each case is analyzed to identify its cause and how it might have been prevented. It then looks at how failures in structural modelling can lead to big problems if they are not identified before construction is undertaken. Beyond this it examines how contract arrangements can encourage or prevent problems in the designing and building processes. It concludes with an examination of the role research and development in preventing failures. By identifying the differences between shoddy economizations and genuine efficiency savings, this book offers savings in the short term which won’t be at the expense of a structure’s long-term performance. Invaluable reading if you’re designing or building concrete structures and want to avoid problems which could be expensive or embarrassing further down the line.

Mohiuddin Ali Khan ... 436 pages - Publisher: Butterworth-Heinemann (March, 2013) ... Language: English - ISBN-10: 0323281869 - ISBN-13: 978-0323281867

Earthquake engineering is the ultimate challenge for structural engineers. Even if natural phenomena involve great uncertainties, structural engineers need to design buildings, bridges, and dams capable of resisting the destructive forces produced by them. These disasters have created a new awareness about the disaster preparedness and mitigation. Before a building, utility system, or transportation structure is built, engineers spend a great deal of time analyzing those structures to make sure they will perform reliably under seismic and other loads. The purpose of this book is to provide structural engineers with tools and information to improve current building and bridge design and construction practices and enhance their sustainability during and after seismic events. In this book, Khan explains the latest theory, design applications and Code Provisions. Earthquake-Resistant Structures features seismic design and retrofitting techniques for low and high raise buildings, single and multi-span bridges, dams and nuclear facilities. The author also compares and contrasts various seismic resistant techniques in USA, Russia, Japan, Turkey, India, China, New Zealand, and Pakistan.

Steen Krenk ... 360 pages - Publisher: Cambridge Univ. Press; (August, 2009) ... Language: English - ISBN-10: 0521830540 - ISBN-13: 978-0521830546

This book presents a theoretical treatment of nonlinear behavior of solids and structures in such a way that it is suitable for numerical computation, typically using the Finite Element Method. Starting out from elementary concepts, the author systematically uses the principle of virtual work, initially illustrated by truss structures, to give a self-contained and rigorous account of the basic methods. The author illustrates the combination of translations and rotations by finite deformation beam theories in absolute and co-rotation format, and describes the deformation of a three-dimensional continuum in material form. A concise introduction to finite elasticity is followed by an extension to elasto-plastic materials via internal variables and the maximum dissipation principle. Finally, the author presents numerical techniques for solution of the nonlinear global equations and summarizes recent results on momentum and energy conserving integration of time-dependent problems. Exercises, examples and algorithms are included throughout.

The engineering community generally accepts that there exists only a small set of closed-form solutions for simple cases of bars, beams, columns, and plates. Despite the advances in powerful computing and advanced numerical techniques, closed-form solutions remain important for engineering; these include uses for preliminary design, for evaluation of the accuracy of approximate and numerical solutions, and for evaluating the role played by various geometric and loading parameters. Eigenvalues of Inhomogeneous Structures: Unusual Closed-Form Solutions offers the first new treatment of closed-form solutions since the works of Leonhard Euler over two centuries ago. It presents simple solutions for vibrating bars, beams, and plates, as well as solutions that can be used to verify finite element solutions. The closed solutions in this book not only have applications that allow for the design of tailored structures, but also transcend mechanical engineering to generalize into other fields of engineering. Also included are polynomial solutions, non-polynomial solutions, and discussions on axial variability of stiffness that offer the possibility of incorporating axial grading into functionally graded materials. This single-package treatment of inhomogeneous structures presents the tools for optimization in many applications. Mechanical, aerospace, civil, and marine engineers will find this to be the most comprehensive book on the subject. In addition, senior undergraduate and graduate students and professors will find this to be a good supplement to other structural design texts, as it can be easily incorporated into the classroom.

This new book sets out a method for carrying out plastic analysis of complex structures without the need for specialist tools.

Odd E. Gjørv ... 232 pages - Publisher: CRC Press; 1st edition (March, 2009) ... Language: English - ISBN-10: 0415414083 - ISBN-13: 978-0415414081

By designing in corrosion prevention and through preventive maintenance, the overall service cost of a concrete structure can be substantially reduced. This book takes a probabilistic approach to the engineering design issues for controlling durability and service life of concrete structures in severe environments. Many durability problems are caused by poor quality control as well as special problems during concrete construction. The issue of construction quality and variability need to be grasped before durability can be successfully controlled. This book helps by giving: Reviews of field performance, deteriorating processes and current codes and practice + methods for calculation of corrosion probability; performance-based concrete quality control; corrosion prevention and preventive maintenance + calculation of life cycle costs and life cycle assessment + recommended job specifications.
