摘　　要：当带构造柱组合墙因构造柱截面尺寸、组合墙材料强度等条件受限而设计中必须辅以加固面层,使其能满足结构受力要求时,便产生了有别于＂恢复性加固＂的所谓＂加强型加固＂的概念和型式。鉴于此,对4种不同加固材料与方法的带构造柱组合墙在出平面偏心受压下墙体开裂并缝宽达到0.3 mm后的抗震性能进行了低周反复水平荷载下的试验研究。结果表明：4种加固方案均能显著增强组合砖墙的抗震性能,但不同加固方案对抗震性能的影响有所不同。通过试验结果分析,找出了各种加固方案的优缺点,为工程抗震设计提供了参考。When a composite wall with a structural column is limited by a section size of the structural column,a material strength of the composite wall and other conditions,a reinforcement surface layer must be used in the design to meet the structural stress requirements,and thus a concept and a form of so called ＂enhanced strengthening＂different from ＂recovery strengthing＂are generated. Therefore,the seismic behavior of the composite wall with a structural column when the wall cracking caused by out-of-plane eccentric compression and the seam width reached0. 3 mm was studied under quasi-satic loading test,which was conducted on 4 specimens with different reinforcement materials and methods. The experimental results indicated that the 4 reinforcement schemes could enhance the seismic behavior of the composite brick wall obviously,while different reinforcement schemes produced different effects on the seismic behavior. By analyzing the experimental results,the advantages and disadvantages of the reinforcement schemes could provide reference for the construction seismic design.
