Study on dynamic response of masonry building to blasting and natural seismic waves

摘要

Seismic effect caused by blasting and natural seismic waves, which directly threatens safety of peripheral buildings, is the focus and difficulty to be solved in structural seismic field. A multi-layer masonry building was taken as analyzed object, proper resilience model and time-history method were adopted to develop a theoretical and numerical model. Based on numerical results, differences between structural dynamic response to blasting seismic waves and natural seismic waves were compared and discussed, which will provide reference for study on seismic performance of buildings under the action of the two kinds of seismic waves.
