【Abstract】 The elastic stiffness of the panel zone in diaphragm-through joints between square steel tubular column and H-shaped steel beam subjected to beam moments was studied. The panel zone deformation mechanism of diaphragm-through joints was analyzed. Based on reasonable assumptions,the elastic stiffness formula of the panel zone,which considered shear deformation of the panel zone,was theoretically derived. Based on the verified finite element model,parametric analysis of diaphragm-through joints was conducted. The proposed formula was proved through the comparisons of theoretical results and FEM results,which indicated the accuracy of the proposed formula.更多还原
