Based on the test of three cross bore chain hollow block bearing masonry walls under the low cyclic reverse load, the failure modes, hysteresis characteristic, deformability, stiffness degradation and other seismic behaviors were studied. The test results show that the masonry wall with construction column and horizontal reinforced concrete strips can increase cracking resistance and load\|bearing capacity, and this new type of masonry wall has good seismic behavior.Keywords:masonry structure; cross bore chain block; construction column; seismic behavior*國家自然科學基金項目(50978090)。作者簡介:吳方伯, 教授,Email:wfbprof@163.com。參考文獻[1]閆維明,周宏宇,周錫元,等. 帶構(gòu)造柱雙排孔混凝土空心砌塊墻抗震性能試驗研究[J]. 建筑結(jié)構(gòu)學報,2005,26(4):64\|69.[2]楊偉軍,施楚賢. 配筋砌塊砌體剪力墻抗剪承載力研究[J]. 建筑結(jié)構(gòu),2001,31(9): 25\|31.[3]周炳章. 砌體結(jié)構(gòu)抗震的新發(fā)展[J]. 建筑結(jié)構(gòu),2002,32(5): 69\|72.[4]唐岱新,宋憲民. 帶芯柱陶粒混凝土砌塊墻體抗側(cè)力性能[J]. 哈爾濱建筑工程學院學報,1993(2): 69\|73.[5]楊德健,高永孚,孫錦鏢,等. 構(gòu)造柱\|芯柱體系混凝土砌塊墻體抗震性能試驗研究[J]. 建筑結(jié)構(gòu)學報,2000,21(4):22\|27.
