摘　　要：为实现构造柱-芯柱体系砌块结构的基于性能的抗震设计,选取构造柱-芯柱体系砌块墙体为研究对象,以位移角作为性能水准的评价指标,根据大量抗震性能试验和数值分析结果,对构造柱-芯柱体系砌块墙体的抗震性能水准进行定量划分,即:充分运行对应于[θ]<1/2 049;损伤运行对应于1/2 049≤[θ]<1/323;生命安全对应于1/323≤[θ]<1/191;接近倒塌对应于[θ]≥1/191.研究成果为震后砌块墙体损伤程度的宏观判定提供了帮助,并为实现砌块结构"多级设防"提供了参考.For the implementation of performance based seismic design of block structures with tie columns and core columns, and according to the seismic performance of the experimental and numerical results, four performance（Sufficient operation, Damage operation, Life safety, Near collapse） are divided quantitatively with three displacement angles, i. e. 1/2 049,1/323,1/191. The results of this research provide help for structure design and the macroscopic decision on damage degree of concrete block walls after earthquake, promote the multi-performance levels seismic design, and have vast importance to the concrete block structures of the performance-based seismic design.
