Abnormal loads can produce localized damage that eventually cause progressive collapse of the whole reinforced concrete (RC) structure. This might have devastating financial repercussions and numerous severe casualties. Numerical simulation, using finite element method (FEM), consequences abnormal on buildings is thus required to avoid significant expenses associated with testing full-scale sav...

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