Abstract:: Four full-scale reinforced concrete frames, including one bare frame without infilling walls and three infilled frames with the new cross hole hollow block masonry, were tested to study the seismic performance under constant vertical force and horizontal low reversed cyclic loading. The damage behavior, hysteretic characteristics, skeleton curve, displacement ductility, stiffness degradation, strength degradation and energydissipating capacity of frames with different types of connections were studied. The results show that the seismic performance of flexible connection specimen is between empty framework and rigid connection specimens, and the seismic performance of the specimen whose frame beam and the infilled wall are connected by tie steel bars has been improved relative to unset specimen, but the increase is limited.
