Experimental study on seismic behavior of concrete block bearing walls

Concrete block is the most competitive in new wall materials. For further researching on seismic performance of masonry structures, this paper carries out test research on 6 specimens under cyclic loading, and obtains test date including hysteretic curve, skeleton curve, bearing capacity, ductility and energy dissipation etc. Major influence factors are listed as following: constructional column, block type and transverse steel bar. According to observing experimental phenomenon and analyzing test results, this article has a conclusion: Constructional column is an important structural measure in masonry structures, it can restrain concrete block bearing wall effectively. Specimens with constructional columns and transverse steel bars have good seismic behaviors and do not collapse under strong earthquakes.
