The seismic design code has been taken strictly for many kinds of architecture in recent years. However, a lot of buildings are located at the fault zone because the land of Taiwan is not enough for people having such a large living space. The buildings would be damaged and people would be put in danger if the fault dislocates, causing permanent ground displacement. It is a crucial issue by now for Taiwan to profoundly analyze the dislocation of the fault. This research includes implicit dynamic finite element method and Morh Coulomb model, analyzing experimentally the reverse fault. It is expected that be applied in earthquake engineering by figuring out the best analyzing mode. Morh Coulomb model is derived from the plastic flow method, which is from the theory of plasticity, to determine if the stress state of the soil is plastic or not. If so, the soil parameters should be modified, corresponding to the adjustment of the relationship between stress and strain. According to the results after analyzing, there are some specified problems for dynamic program. For an instance, the results are mainly influenced by the mass and the damping in pseudo-static experiment. In order to remove the influence of the inertial force, it needs to find the most suitable parameters while doing the parameter analysis for mass and damping. Finally, the suggestions are made for implicit dynamic finite element method to analyze the reverse fault experiment more comprehensively in the future.
