Through the test, the failure patterns and bearing capacity are obtained. Experimental study results show that the major failure modes of steel reinforced high strength concrete short pier shear wall are shear diagonal compression failure and bending-shear failure. SRHC has large bearing capacity, stiffness and ultimate rotation capacity, but the displacement ductility and excellent seismic energy dissipation performance are less than the normal steel reinforced concrete.Keywords:high strength concrete; steel reinforced concrete (SRC);short pier shear wall; seismic behavior國(guó)家自然科學(xué)基金(50968003)。作者簡(jiǎn)介:苗亞州(1957-),男,海倫縣人,高級(jí)工程師,總工,國(guó)家注冊(cè)監(jiān)理工程師,Email:13807803722@139.com。參考文獻(xiàn)[1]容柏生. 高層住宅建筑中的短肢剪力墻結(jié)構(gòu)體系[J]. 建筑結(jié)構(gòu)學(xué)報(bào),1997,18(6):14-19.[2]程紹革,陳善陽(yáng). 高層短肢剪力墻結(jié)構(gòu)振動(dòng)臺(tái)試驗(yàn)研究[J]. 建筑科學(xué),2000(1):12-16.[3]趙鴻鐵. 鋼與混凝土組合結(jié)構(gòu)[M]. 北京:科學(xué)出版社,2000.[4]陳宗平,薛建陽(yáng),趙鴻鐵. 型鋼混凝土異形柱抗震性能試驗(yàn)研究[J].建筑結(jié)構(gòu)學(xué)報(bào),2007,28(3):53-61.[5]GB50011—2001建筑抗震設(shè)計(jì)規(guī)范[S].北京:中國(guó)建筑工業(yè)出版社,2001.[6]VARMA A H, RIDES J M.
