摘　　要：混凝土小型空心砌块建筑是我国今后民用住宅建筑的重点发展方向之一，研究其开孔砌体的抗震性能具有重要的理论意义和应用价值。本文提出了一种适用于小砌块建筑的新型开孔墙体结构型式——“约束开孔砌体”，旨在通过增设钢筋混凝土约束构件——芯柱和水平条带，来提高砌体的承载能力和变形能力。文中对三类不同开孔形式的小砌块约束砌体进行了探索性的试验研究。试验结果表明，小砌块约束开孔砌体具有良好的抗震性能，值得进一步研究。In China,small size concrete block(SSCB) structure has become one of the major ways of future civil housing construction.It is very necessary and useful to carry out research on seismic behavior of SSCB masonry with opening.This article is just about the experimental research carried out with three SSCB masonry walls,each with one type of opening respectively.A new kind of structural method,reinforced concrete inner columns and horizontal strips placed around the openings and in the walls as restraining members,was adopted in the tests.The result of the tests shows that SSCB restraint masonry with opening has good seismic behavior,and it is worth to do further research on this subject.
