摘　　要：通过对分别设置构造柱和芯柱的整体、开窗洞、开门洞的三类加气混凝土砌块墙进行拟静力抗震试验,比较两种抗震构造措施对墙体抗震性能的影响。研究在水平荷载作用下各墙体的破坏过程,通过试验得到的滞回曲线,讨论各墙体的抗剪承载力、变形性能和耗能能力等性能指标,并分析了不同构造措施下墙体的抗震性能差异。试验表明,在墙体两端设置构造柱墙体的抗震抗剪承载力高(包括开裂荷载和极限荷载),刚度较大;在墙体两端和洞口两侧均设置芯柱的墙体由于洞口处有芯柱约束,后期承载力下降缓慢,有更好的后期变形能力;在耗能方面两者能力相当。The quasi-static tests were conducted on three types of aerated concrete block composite walls（the wall,the wall with windows,the wall with door） with structural concrete columns and core columns.The influence of two seismic constructional measures on the seismic behavior of the walls were compared.The failure process of the walls under horizontal load was studied,and the hysteretic curves were obtained.The discussion on the shear bearing capacity,deformation and energy dissipation capacity was carried out,and the difference of seismic behavior of the walls with different structural measures were compared.The test results showed that shear bearing capacity（including crack loading and ultimate load） and stiffness of the walls with structural concrete columns were higher than the walls with core columns.As the confinement of core columns near both sides of openings,the bearing capacity decreased slowly at later stage,and the deformation capacity was better.The energy-dissipation capacity of two walls was similar.
