Abstract

In this paper, the strength and stiffness of different roof structures has been investigated, in order to establish their ability to act as in-plane diaphragms for stressed skin design. A total of 10 roof panels were examined by testing with shear connectors placed along the rafters. In each test set-up, the roof was constructed using top-hat purlins and standard sheeting profiles or composite panels. Different types of roofs, such as single and double skin, have been investigated, all using top hat shaped purlins. The experimental strength and stiffness of each panel was then compared against established theoretical methods. It was demonstrated that although it is possible to closely estimate the ultimate strength of the structure using standard calculation methods, it is often more difficult to accurately calculate its stiffness. As the panel stiffness is a function of many variables, testing is still the recommended method, in order to investigate the flexibility of modern roof panels. © 2010 Taylor & Francis Group, London.
