［摘要］通過(guò)對(duì)1片普通鋼筋混凝土現(xiàn)澆剪力墻和1片預(yù)制帶肋疊合整體式剪力墻的擬靜力試驗(yàn)，對(duì)兩片剪力墻的破壞形態(tài)、承載力、變形能力、滯回特性、剛度退化、耗能能力等進(jìn)行研究分析。結(jié)果表明：兩片剪力墻均發(fā)生彎曲破壞；疊合剪力墻整體性好，其破壞形態(tài)、裂縫分布、滯回特性、剛度退化趨勢(shì)與現(xiàn)澆剪力墻近似；疊合剪力墻的整體剛度大于現(xiàn)澆剪力墻，位移延性及耗能性能與現(xiàn)澆剪力墻相近。［關(guān)鍵詞］疊合剪力墻; 預(yù)制帶肋疊合板; 擬靜力; 抗震性能中圖分類號(hào)：TU398 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)10-0014-06

The failure patterns, bearing capacities, hysteretic characteristics, stiffness degradations and energy dissipation capacities of the two shear wall specimens were investigated. The result shows that there are flexural failures in both of the two specimens; superimposed shear wall has well integral properties and its failure pattern, crack distribution, hysteretic characteristic and stiffness degradation potential are similar as those of cast-in-situ shear wall; the integral stiffness of superimposed shear wall is higher than that of cast-in-situ shear wall and the displacement ductility and energy dissipation capacity of superimposed shear wall are close to those of the cast-in-situ shear wall.Keywords: superimposed shear wall; prefabricated superimposed slab with ribs; quasi-static; seismic behavior
