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 (minimal 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, the shapes of which are supposedly known, such as suspension bridge cables.
The book presents numerical modelling of the structural form and behaviour of tension structures, and also addresses misconceptions related to their design. It provides unique insights into the most commonly used computational methods, emphasising their main strengths and limitations. The intention of the book is to provide a balance between analytical and pictorial aspects of the subject. Examples presented demonstrate the potential of tension structures as an art form.
Contents include: Form-finding; Geometrically non-linear behaviour; Dynamic relaxation method; Case studies of cable roof structures; Tension cables in suspension bridges and Modelling of tension membranes.
