Abstract:

A full-scale model of a one-bay masonry structure with ring beams and tie columns was established. Then,the seismic response of a single-storey ten-bay masonry structure was simulated by pseudo-dynamic tests,and the failure process of the specimen under loads was observed. Moreover,a seismic response analysis program for the test model was compiled to calculate the structural displacement response,and the results were compared with the test ones. Finally,the theoretical bearing capacity of the test structure was calculated by using different analytic equations,and the results were also compared with the test ones. It is found that ( 1) the structure as a prototype of the test model with ring beams and tie columns,which can withstand the seismic excitation with a peak ground acceleration of 1.6g,exhibits satisfactory seismic behavior; ( 2) the maximum bearing capacity of the structure with ring beams and tie columns increases by 20%~50%; and ( 3) the details of seismic design are helpful in improving the seismic behavior of masonry structures.
