Finally, stochastic vibration analysis of a two-floor frame structure by blasting seismic action is done by finite element program ANSYS. In order to contrast, that by nature seismic action is also done here, and displacement field, velocity field and stress field of this two kind of condition are obtained, and differences of the structure damage mechanics by two kind of action are analyzed. Dynamic reliability analysis of the two-floor frame structure is done using of simulation results, obtaining the safe reliability level of the structure by seismic action, and seismic safety evaluation of the frame is completed.
