SEISMIC PERFORMANCE ASSESSMENT OF BRICK MASONRY STRUCTURES WITH PRECAST SLABS BASED ON DETERIORATION OF FREQUENCY

In order to study the seismic performance assessment method of brick masonry structures with precast slabs，the bi-directional pseudo-dynamic test of 1∶ 2 scaled building model was carried out． The change of rigidity and frequency of the structure was introduced in the test，and a seismic performance assessment method based on frequency was presented． The evaluation results based on frequency were very close to those based on rigidity，and frequency-based method had a simpler calculation process，and the results were also closed to real damage condition． Therefore，the frequency-based method could be applied in seismic performance evaluation of brick masonry structures with precast slabs．
