Introduction to Cable Roof Structures


Book Description

The second edition of this book provides structural engineers with a concise introduction to the architectural, structural and technological aspects of cable roofs, and supplies sufficient information for engineers to carry out their own designs. The improved methods for generating wind and earthquake histories have been included as the trend in modern design codes seem increasingly to require that dynamic response of other forms of non-linear structures such as guyed masts is considered at the design stage.




Tension Structures


Book Description

The tension structures discussed in this book are predominantly roofing forms created from pre-stressed cable nets, cable trusses, and continuous membranes (fabric structures). A unique feature in their design is "form-finding" - an interactive process of defining the shape of a structure under tension. The book discusses the role of stable minimal surfaces (minimum energy forms occurring in natural objects, such as soap films) in finding optimal shapes of membrane and cable structures. The discussion of form-finding is extended to structural forms whose shape is supposedly known, such as suspension bridge cables.

Elements of Spatial Structures


Book Description

This excellent text highlights all aspects of the analysis and design of elements related to spatial structures, which have been carefully selected from existing structures. Analysing the design of elements of any full scale structure that contains facilities that have already been constructed makes good economic sense and avoids duplication in respect of research and development, the decision-making process and accurate design criteria for new constructed facilities.




Widespan Roof Structures


Book Description

Presents world thinking on the design and construction of large covered spaces. This book aims to offer insights into many of the innovative construction design projects. It explores the advances within stressed membrane roofing, atria and glass structures, with a focus on international developments. It also addresses the problems of construction.




Computational Methods in Earthquake Engineering


Book Description

This book provides an insight on advanced methods and concepts for the design and analysis of structures against earthquake loading. This second volume is a collection of 28 chapters written by leading experts in the field of structural analysis and earthquake engineering. Emphasis is given on current state-of-the-art methods and concepts in computing methods and their application in engineering practice. The book content is suitable for both practicing engineers and academics, covering a wide variety of topics in an effort to assist the timely dissemination of research findings for the mitigation of seismic risk. Due to the devastating socioeconomic consequences of seismic events, the topic is of great scientific interest and is expected to be of valuable help to scientists and engineers. The chapters of this volume are extended versions of selected papers presented at the COMPDYN 2011 conference, held in the island of Corfu, Greece, under the auspices of the European Community on Computational Methods in Applied Sciences (ECCOMAS).




Masted Structures in Architecture


Book Description

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.




Advances in Structures


Book Description

This volume is an outcome of the international conference on advances in structures: steel, concrete, composite and aluminium in Sydney in 2003. It focuses on researches in composite design, fire engineering, light gauge construction, advanced structural analysis and concrete filled tubes.




Tensegrity Structures and their Application to Architecture


Book Description

Tensegrity structures are really intriguing: bars floating in the air, without any contact to a solid support, attached only by wires to other bars… that are also floating in the air! The aim of this work is to serve as an introduction to such an atypical kind of structure. It tries to explain everything about the controversial origins and polemic fatherhood; tensegrities from various fields, other than Architecture, structural principles, characteristics, advantages and weakness; precedent and current works and patents; and finally, some new proposals, proving that it is possible to find some applications to architectural and engineering purposes. In conclusion, this work tries to be a guide and reference to a new world of structural possibilities that is blooming and finding its path.
