Abstract


The explicit method for solving dynamic system equation of structures is compared to the implicit methods and its advantages are described. A four story steel structure is subjected to an extreme earthquake and structure is beginning to collapse. The Explicit Finite Element Method (EFEM) is used for the analysis of structure. The seismic behavior of structure is evaluated by following the collapse process of structure. Results show that the EFEM can be simulated the collapse process of structures by predicting the location of collapse initiation and modeling the failure process of elements, joints and members during earthquake.
