摘　　要：为了提高混凝土结构建筑抗震性能,提出基于模糊理论的混凝土结构建筑抗震性能设计方法,构建混凝土结构建筑的滞回力学分析模型,结合刚度模拟方法进行混凝土结构建筑抗震恢复力估计,分析混凝土结构建筑的双向板荷载—变形关系,分析混凝土结构建筑的荷载特征,结合板块内力平衡方程进行混凝土结构建筑抗震力学的模糊参数估计,采用有限元分析理论进行混凝土结构建筑抗震性能量化分析,根据混凝土结构建筑的荷载—位移曲线实现混凝土结构建筑抗震性能的优化设计。测试结果表明,采用该模型进行混凝土结构建筑抗震性能设计提高了混凝土结构的抗震能力,极限承载力得到提升。A hysteretic mechanical analysis model of concrete structures was constructed to estimate the seismic resilience of concrete structures by stiffness simulation.The two-way slab load-deformation relationship of the concrete structures was also analyzed.Furthermore,the fuzzy parameters of concrete structures’seismic mechanics were estimated by plate internal force equilibrium equation.The seismic performance of the building was analyzed with finite element analysis.Finally the design of concrete structures’seismic performance was optimized according to the load-displacement curve of concrete structures.The test results show that the seismic performance of concrete structures designed with this model is improved and the ultimate bearing capacity was raised.
