摘　　要：采用一种简化的极限分析方法来确定钢筋混凝土结构的极限状态及其拍应的极限承载力，将绍构的非线性抗力值等效为线性抗力值，使得结构的随机地震响应可以按照线弹性理论计算，避免了非线性分析的各种困难，以便于工程应用。同时，针对三水准设防标准，对钢筋混凝土框架房屋进行了可靠性研究。A simplified limit analysis approach is adopted to determine the limit state and its limit bearing capacity of RC structure, the nonlinear bearing capacity is equivalently linearized to some linear capacity, which makes the random seismic response calculated linear, avoids many diffculties in nonlinear analysis, and makes it convenient to be used in engineering. To counter three levels preparednes standard, reliability analysis of RC frame house is carried out at the same time.
