Progressive Collapse Simulation of Underground Structure under Internal Blast Loading
Much research has been directed at the progressive collapse of the over-ground structures under free air burst loading in recent years, while less work has been stressed on the progressive collapse of the underground structures, which subjected to internal blast loading. A proposed method is presented in this paper to simulate the progressive collapse of one underground reinforced concrete frame under internal blast loading, which is using LS-DYNA. The numerical results indicate that the proposed method is more accurate and timesaving, compared with alternative load path method (ALPM) and direct simulation method (DSM).
