Cable-Suspended Roofs, Second Edition

by: Prem Krishna, PN Godbole


Abstract: The system of supporting large span roofs using high strength steel cables had been adopted since the 1950s and was well developed by the 1970s when the original edition of Cable Suspended Roofs, authored by Prem Krishna, was published in 1978. The intervening 35 years witnessed the gradual evolution of cable roof structures with exquisite aesthetic appearance, and a wide range of spans and applications. There have also been developments in analytical approaches and software packages, besides materials of construction, particularly fabrics, motivating this updated edition co-authored by PN Godbole. Updating the knowledge in the original edition, this volume deals with static and dynamic analysis, model studies, design, construction materials and examples on simple and pretensioned, air supported as well as fabric, roofs. The book also includes description of computer software which can be used for the static or dynamic analysis of cable assemblies of any configuration, using the 'tension coefficient' or the finite element approach. The software can be accessed by the reader through a link. Some of the highlights of this edition: • one-stop reference covering almost 60 years of research and development • Finite Element Method in two chapters dealing with analysis • substantial new material on fabric roofs • special section on practical examples • detailed list of references for further study While the work will particularly appeal to architects and structural design engineers in analyzing, designing and constructing cable roofs alongside researchers and teachers, it will also prove useful to anybody dealing with cable structures other than roofs.

Authors:

Prem Krishna obtained Bachelors as well as Masters degrees in Civil and Structural engineering respectively from the erstwhile University of Roorkee (now IIT Roorkee), and his Doctorate from the Imperial College of Science, Technology and Medicine, London, UK. He then joined the faculty of Civil Engineering at the University of Roorkee, where he had a long and distinguished career in teaching, research and sponsored design work, which he has continued to engage in actively even after retirement. Recognized nationally and internationally for his specializations on large span steel structures (in particular cable structures) and wind engineering, he has held important professional positions.

PN Godbole obtained Bachelors (Honours) degree in Civil Engineering from IIT Bombay, Masters (Structures) degree from University of Roorkee, and his Doctorate from University of Wales, Swansea, UK. He worked in various capacities at the University of Roorkee from 1963 onwards and retired as Professor of Civil Engineering. With wide experience in teaching, research and industrial consultancy, he has published more than 120 research papers and supervised 25 Doctoral candidates. His main areas of interest include FEM, CAD, wind effects on structures and design of steel structures.
