Abstract
This thesis describes the topics that are closely relevant to the inelastic dynamic behaviour of steel roof deck diaphragms. In total, four groups (12 specimens) of large-scale diaphragm tests were carried out. These tests, together with the tests finished by earlier researchers, demonstrate that short sheet length (with end laps) will largely decrease the in-plane shear stiffness, but will not noticeably influence the shear strength. The roofing material composed of various wood or gypsum based panels, insulation boards, vapor barrier, waterproof membranes, etc. can increase both the diaphragm shear strength and stiffness if appropriately attached to the steel deck. The thermal barrier, e.g. the gypsum board in the test model, which is quite rigid in its plane and is mechanically fastened to the steel deck, was found to influence the diaphragm properties to the greatest extent. This was also verified by a 3-D stress and deformation analysis by FEM of deck panel-gypsum board assembly. (Abstract shortened by UMI.)
