摘　　要：通过分析混凝土多孔砖砌体前期试验研究结果,综合考虑结构变形和能量耗散双因素的影响,采用双参数破坏指标改进了传统的砌体结构抗震破坏准则.基于一幢混凝土多孔砖砌体房屋的地震破坏指标计算结果以及进一步的抗震性能分析,评价该结构的抗震性能.分析结果表明,该破坏指标适用于混凝土多孔砖砌体结构的抗震可靠性分析.According to the analysis of prophase research results on concrete perforated brick masonry structure, the influences of structural deformation and energy dissipation were overal considered. Double - parameters damage guide line was applicable to improve the traditional masonry structure＇ s seismic damage guide line. Basing on calculation results of a concrete perforated brick masonry building＇ s seismic damage guide line and the further seismic reliability analysis, the structure＇ s seismic safety performance was evaluated. The analysis results showed that the double - parameters damage guide line is applicable to concrete perforated brick masonry structure＇s seismic reliability analisis.
