Abstract:Explosion seismic waves were numerically studied with a non-stationary random process model.A practical simulating method of single-pointexplosion seismic waves was presented,in which the effects of distance and mass of explosive were put into consideration.Based on the case of a 15-story-frame structure,a model of beam and shell 3-D finite element structure was built and the frequency of structure and the mode of vibration were computed in the study;furthermore,the structural dynamic response was discussed under the simulating explosive seismic wave.The weak story of the structure is determined,according to the results of dynamic responses.The information can be used for the anti-seismic design of structure.
Keywords:explosive seismic wave  non-stationary random process  numerical simulation  frame structure  time history analysis
