[提要] 通过对一榀1/2比例底部一层两跨框架、上部三层钢筋砼一砖砌体横向组合墙结构的模型伪静力试验,研究了底框架、组合墙和框墙梁在竖向荷载或/和水平地震力同时作用下的破坏过程和机理、抗震性能及框支组合墙变形、承载力等问题。

under low cyclic loadings, seismic properties and failure mechanism of the structure and its wall-beam are studied under vertical and/or seismic loads. The evaluated shear strength and deformation are in agreement with the measured.
