Abstract:The progressive collapse of the spatial grid structure is the focus and difficulty of the current research. The stability problem of the single-layer latticed shell structure is more prominent due to its low redundancy. In this paper, the dynamic nonlinear analysis of the Zhoukoudian large-span single-layer latticed shell structure is carried out to study its progressive collapse process by the finite element software ABAQUS. The results show that the structure eventually collapse under 7 times the gravity loa… Show more
