摘　　要：对3片自保温混凝土砌块墙体进行了低周反复加载试验,研究了高宽比对墙体破坏特征和抗震性能的影响。根据试验研究及理论分析,运用ABAQUS6.12建立了合理的有限元模型,对不同高宽比的墙体进行了有限元分析,并与试验结果进行比较,验证了外墙混凝土砌块保温层部分对墙体抗震性能的贡献。结果表明,两端开口式保温承重砌块墙体具有良好的抗震性能,研究结果可为实际工程应用提供参考。In the experiment, there are three self-insulating concrete block walls designed and tested under combined uniformly distributed constant vertical load and low-cyclic lateral load to investigate the seismic performance of them. Based on experimental study and theoretical analysis using ABAQUS 6.12 reasonable finite element model is established. The walls with different aspect ratio make finite element analysis to compared with the test results,and validate the contribution of insulation layer of external wall concrete block to the strength capacity. The results show that the open -ended thermal insulation load -bearing block wall has good seismic performance?and the research results can provide reference for the engineering application of the new composite thermal insulation block wall. Key words: composite insulation block wall.
