Design of Plate and Shell Structures

This exciting text is written primarily for professional engineers interested in designing plate and shell structures. It covers basic aspects of theories and gives examples for the design of components due to internal and external loads as well as other loads such as wind and dead loads. Various derivations are kept relatively simple and the resultant equations are simplified to a level where the engineer may apply them directly to design problems. More elaborate derivations and more general equations may be found in the literature for those interested in a more in-depth knowledge of the theories of plates and shells.

Theory and Design of Plate and Shell Structures

This is the first book to integrate the theory, design, and stability analysis of plates and shells in one comprehensive volume. With authoritative accounts of diverse aspects of plates and shells, this volume facilitates the study and design of structures that incorporate both plate and shell components. Drawing on his extensive experience in plate and shell theory and design, the author: –introduces the principles and applications of bending of plates; membrane theory and bending of shells; and stability of plates and shells; –explains the crucial elements of roof structure analysis and finite element formulations; –explores topics of current interest, such as plastic design of plates and approximate solution of membrane stress in shells of revolution and in buckling of shells; –describes how to select design approaches according to the functional and safety requirements of specific structures. Each chapter demonstrates the principles, practical applications, and design of a plate or shell component using real-life examples, providing the reader with an in-depth, unified understanding of the theory and function of the component. Chapters are written to be as independent of each other as possible to allow for selective reading on either plates or shells. In addition, the text is conveniently supplemented by appendices of Fourier Series and Bessel Functions. Integrating the fundamental and applied aspects of plate and shell theory, this volume serves as an essential text for graduate students and as an easy-to-use reference for engineers in mechanical, civil, and aeronautical engineering.

Wind Loads: Guide to the Wind Load Provisions of ASCE 7-10

This helpful guide focuses on the wind load provisions of Minimum Design Loads for Buildings and Other Structures, Standard ASCE/SEI 7-10, that affect the planning, design, and construction of buildings for residential and commercial purposes. The 2010 revision of the Standard significantly reorganized the wind load provisions, expanding them from one to six chapters. Simplified methods of performing calculations for common situations were added to the Standard, and guidelines for components and cladding were gathered in a single chapter. Wind Loads provides users with tools and insight to apply the Standard in everyday practice. This revised and updated guide introduces readers to the relevant sections of the Standard and provides a comprehensive overview of the design procedures and the new wind speed maps. Ten chapters with 14 worked examples demonstrate the appropriate use of analytical and simplified procedures for calculating wind loads for a variety of common structure types. The guide also answers more than 30 frequently asked questions, grouped by topic. This book is an essential reference for practicing structural engineers, as it offers the most authoritative and in-depth interpretation of the wind loads section of Standard ASCE/SEI 7-10.

Structural Systems: Behaviour and Design

Promoting and underlining the importance of structural thinking, Structural Systems: Behaviour and Design will provide readers with a comprehensive understanding of the behaviour of a wide range of structural systems based on the load-carrying mechanisms involved. Bringing together a wide array of structural types and covering the behaviour and design of both steel and reinforced concrete (prestressing inclusive), the author employs an integrated qualitative and quantitative approach to the examination of each structural element. Topics are introduced in a logical manner, building on concepts discussed and explained in previous chapters, providing readers with a sound understanding of the universal principles of structural behaviour and enabling them to apply safe conceptual and preliminary designs, whatever design codes they are working with. The book starts with the fundamental concepts, looking at plane structural systems such as beams, frames, arches and cable structures. In the latter half, the author builds on this, introducing the more advanced topics of spatial structural systems, dynamic behaviour and seismic response, and soil-structure interaction. Each topic is treated in a predominantly practical way and supported throughout with illustrative diagrams, equipping readers with the analytical tools and structural understanding required to undertake the design of complex structures, including bridges, buildings, space covering roofs and foundations. Structural engineers of all levels of experience will find this an accessible and authoritative text, enabling a solid understanding of structural behaviour without dependence on computer-generated models.

Smith’s Elements of Soil Mechanics

This core undergraduate textbook for civil engineers is the first to cover the fundamental changes in the ethos of geotechnical design advocated in the now published Eurocode 7. This code will be fully adopted across Europe by 2010 and its implementation will mean a radical shift to limit state design.

Ian Smith makes understanding this new approach to geotechnical design less daunting to the student with clear explanatory text, detailed illustrations and several worked examples, covering a range of topics including slope stability, retaining walls and shallow and deep foundations. Downloadable spreadsheets help to illustrate how the new Eurocode is applied and the book’s website also gives the worked solutions to self-test questions at the end of each chapter.

Now in its 8th edition, this well-established textbook has been updated and re-designed with improved page layout and illustrations making it the essential user-friendly introduction to soil mechanics and geotechnical design to Eurocode 7.

Reliability-Based Design in Geotechnical Engineering: Computations and Applications

Reliability-based design is the only engineering methodology currently available which can ensure self-consistency in both physical and probabilistic terms.  It is also uniquely compatible with the theoretical basis underlying other disciplines such as structural design. It is especially relevant as geotechnical design becomes subject to increasing codification and to code harmonization across national boundaries and material types. Already some codes of practice describe the principles and requirements for safety, serviceability, and durability of structures in reliability terms.

This book presents practical computational methods in concrete steps that can be followed by practitioners and students. It also provides geotechnical examples illustrating reliability analysis and design. It aims to encourage geotechnical engineers to apply reliability-based design in a realistic context that recognises the complex variabilities in geomaterials and model uncertainties arising from a profession steeped in empiricism.  By focusing on learning through computations and examples, this book serves as a valuable reference for engineers and a resource for students.

Seismic Design Aids for Nonlinear Analysis of Reinforced Concrete Structures

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.
