本文利用可靠度理论的概率公式，并在结构失效概率计算技术的基础上，探讨了承受多种连续可变作用荷载过程的钢筋混凝土柱失效概率的计算技术，其具体方法是采用分段连续线性化极限状态方程，对非线性问题进行简化，这种方法可减少砼结构非线性分析的计算工作。对偏心受压的钢筋砼柱进行实例典型分析表明，采用线性化和高斯过程，得出的远交率的简单计算方法是可行的，并显示了作用荷载及其效应和结构抗力的随机性质。
This paper uses the probability formula of reliability theory, and on the basis of structural failure probability calculation technology, discusses the calculation technology of the failure probability of reinforced concrete columns subjected to a variety of continuously variable load processes. The specific method is to use piecewise continuous linearity. The limit state equation can be used to simplify the nonlinear problem. This method can reduce the computational complexity of the nonlinear analysis of concrete structures. An example analysis of an eccentrically stressed reinforced concrete column shows that a simple calculation method for the out-crossing rate obtained using the linearization and Gaussian processes is feasible and shows the random nature of the applied load and its effect and structural resistance.
