This book aims to 'bridge the gap' between engineers' and architects' understanding of structural form. It aims to inspire designers to develop innovative and viable structural forms. This book is presented in two parts. The first part is theoretical and investigates source of inspiration for developing structural form; learning from natural forms; applying our own intuition; seeking inspiration from precedents; applying understanding of structural principles; and developing design through physical models. The second part is presented through four case studies. They include the Chelsea Flower Show Pavilion by Sarah Wigglesworth Architects and Jane Wernick Associates; the Eden Project by Nicholas Grimshaw Architects and Anthony Hunt Associates; the glass structures by Dirk Jan Postel and Robert Nijsse; and the Dutch Expo 2000 Pavilion by MVRDV Architects and ABT consulting engineers. The case studies all have in common that the imaginative structural forms are in harmony with the architectural concept and, at the same time, present very efficient solutions to technical and structural problems. "Conceptual Structural Design" is essential reading for architects and engineers, and for anyone interested in conceptual structural design.
