摘　　要：本文利用Monte-Carlo数字模拟原理,以同一集系的多条地震加速度时程为输入,利用作者提出的考虑结构低周疲劳特性、首超破坏与累积损伤破坏合一的地震破坏准则,通过时程反应分析,直接统计反应量的随机特征来寻求结构的抗震可靠度,避免了建立地面运动简化模型和求解强非线性随机振动问题带来的近似与误差。在可靠度分析中采用了一次二阶矩的验算点法,将结构抗震可靠性统一到可靠指标β上来分析,便于在工程中实际运用。By means of statistic fundamentals and statistic deduction method, the probability distributions of the stochastic variables in the damage criteria presented by the authors are studied. Making use of results of seismic hazard analysis and the damage criteria, reliability assessment method of shear type structures subjected to different level of earthquakes is put toward. Finally, the reliability of aseismic structures can be simply analyzed in terms of safety index β by first order and second moment method.
