ABSTRACT
Considerable progress has been made in recent decades in the design and construction of structures to cover very large spaces without internal support. This paper describes in some detail a concept which adds to the inventory of structures now available to perform this function. The background to its development, its form and construction details are discussed. An explanation of its structural behaviour and the results of numerical studies follow and., from these, material usage and costs. The method of erection and cladding techniques are then explained and the paper concludes with a range of applications for the system.
