Three-dimensional nonlinear analysis on complex hybrid structure

Three dimensional nonlinear dynamic analysis was carried out by finite element software named CANNY, The whole structure analysis including frame-shear wall structure, local large span spatial structure and post-tensioned prestressed structure was proposed. The results show that the whole structure is good under forces, and slight damage is found even under rare earthquake. Nodes of space truss are destroyed after yielding of main members, and ultimate bearing capacity is fully played. Nodes of steel reinforced concrete column-steel truss show favorable properties on bearing capacity, ductility, capacity of deformation and energy dissipation, and seismic behavior is satisfied.
