摘　　要：为研究双洞口配筋砌块砌体框支墙梁地震前后的受力模式,在拟动力子试验前后进行了底层框架配筋砌块短肢砌体剪力墙结构三层足尺模型的竖向力静载试验.试验结果表明:托梁与上部墙体表现出良好的协同工作能力,其工作模式为拉杆拱.通过对其在拟动力试验前后的受力模式进行了比较,可知带洞口配筋砌块砌体框支墙梁结构体系在墙体受到一定损伤时,并不会使墙梁的受力机理发生明显改变.This paper carried out the vertical static test for both pre-damage and post-damage by the substructure pseudo-dynamic test on the full-scale model which is a three-floor frame-supported reinforced concrete masonry short-leg shear wall structure.The force-transmission mechanism of frame-supported double-hole reinforced concrete masonry was proposed.The testing results show that the good capability to work together is ex-hibited between the joist and upper shear wall,and the working pattern is the tie-arch l...
