［摘要］對(duì)4個(gè)裝配式空心剪力墻試件進(jìn)行擬靜力試驗(yàn)，模擬了不同的軸壓比和剪跨比對(duì)試件抗震性能的影響。通過低周往復(fù)加載試驗(yàn)得到試件的滯回曲線，并分析其延性、耗能性能和剛度特征。試驗(yàn)結(jié)果表明：裝配式空心剪力墻的抗震性能和普通鋼筋混凝土剪力墻抗震性能相似，且空心孔洞和水平拼接縫不會(huì)削弱墻體的受力性能，各個(gè)試件均表現(xiàn)出良好的延性和耗能能力，因此可以通過提高水平拼接縫的位置改善墻體抗震性能。［關(guān)鍵詞］裝配式空心剪力墻; 水平拼接縫; 抗震性能中圖分類號(hào)：TU375 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)10-0032-05
Seismic performance research of prefabricated hollow shear wallZhang Guowei, Xiao Wei, Chen Boshan(Beijing Higher Institution Engineering Research Center of Civil Engineering Structure and Renewable Material, Beijing University of Civil Engineering andArchitecture, Beijing 100044, China)Abstract: Pseudo-static test was carried out on 4 specimens of prefabricated hollow shear wall (PHSW) to simulate effects of different axial compression ratios and height to width ratios on the seismic performance of PHSW specimens. The hysteretic curves of specimens were obtained by low cyclic loading test, and the ductility, energy dissipation and stiffness characteristics of the specimens were analyzed. Experimental results show that the seismic performance of prefabricated hollow shear wall is similar to that of common reinforced concrete shear wall, and hollow holes and horizontal joints will not weaken the mechanical performance of the wall. Each specimen exhibits good ductility and energy dissipation capacity, so the seismic performance of the wall can be improved by raising the horizontal joint′s position.Keywords: prefabricated hollow shear wall; horizontal joint; seismic performance
