中文摘要：

为研究叠合板式剪力墙与基础之间的水平连接部位在地震作用下的受力和变形性能，以及垂直方向剪力墙相交处边缘构件对结构破坏形式的影响，对两个由纵、横向剪力墙和相交处的全现浇T形边缘构件组成的足尺工字形横截面剪力墙试件进行了低周反复加载试验，在此基础上对剪力墙与基础水平连接部位剪切滑移机理进行了分析，并采用非线性有限元分析程序CANNY对试件的受力过程进行了数值模拟分析。研究表明：与普通现浇钢筋混凝土剪力墙相比，叠合板式剪力墙的破坏主要集中在墙板与基础顶面水平接缝附近，塑性范围较小，降低了试件的延性；剪力墙的抗滑移力主要由截面弯压区混凝土的摩擦力承担，由于该试验试件截面翼缘宽度较大，且没有施加竖向轴力，弯矩作用下截面受压区高度很小，导致有效摩阻面积很小，是试件在水平荷载下产生较大的剪切滑移变形的主要原因；采用CANNY中的三维MS模型可以较好地模拟叠合板式剪力墙在地震作用下的反应情况。

英文摘要：

To evaluate behavior of the horizontal connections between the superimposed walls and foundations under seismic load, and the influence of edge elements among the perpendicular walls to the damage pattern of the structure, two full-scale I-shaped section specimens consisting of the perpendicular walls and the cast-in-place T-shaped edge elements were tested under cyclic reversed loads. Based on the test, the shear slip mechanics of the horizontal connections between wall and foundation is analyzed, and then numerical analysis of the specimen is conducted utilizing the 3-D nonlinear structural analysis program CANNY. The study indicates that damage of the superimposed wall mainly occurs near the horizontal connections between wall and foundation, and the inelastic region is relative small, inducing that ductility of the structure is decreased; anti-shear slip ability of the horizontal connections is mainly provided by the friction of the compress region of the cross section, and thus the relative small compress region of the I-shaped cross section is the main reason for the obvious shear slip of the specimens during the test; the 3-D MS element of CANNY is proved to be reasonable and dependable for the I-shaped superimposed walls.
