Abstract

This paper discusses the principles of horizontal timber diaphragm behaviour under in-plane loading, gives guidance on analysis, design and details, and reviews relevant research. Plywood, particle board and solid timber boarding are all relevant sheathing materials for wind and earthquake resistance, provided that appropriate stiffness is provided and the design provisions ensure that brittle failure modes are suppressed.
