[提要] 通过组合墙片和构造柱墙片的对比试验,分析研究了组合墙的承载能力和恢复力特性。试验结果表明,组合墙结构的抗剪能力与构造柱墙片相比有较大的提高,其抗弯性能也有很大的改善,并具有良好的整体性能和恢复力特性,能够满足结构抗震的要求,同时,组合墙结构的承重能力也得以大幅度提高,其轴压比降低了50%,不失为一种在地震区发展中高层砌体房屋的较好结构形式。
[关键词] 组合墙 抗震性能 试验研究The test of combined masonry walls has been carried out to investigate the bearing capacity and elasto-plastic perfonnance. lt is shown that the bearing capacity and flexible reinstate are excellent compared with masonry, because the combined masonry performed as an integrate component has an ability of flexible reinstate.lt means that the higher combined masonry buildings can be constructed with the new structure than the buildings existed.
