摘要
将随机有限元与钢筋混凝土非线性特性相结合,讨论了随机有限元在钢筋混凝土非杆系结构可靠性分析的应用中所涉及到的基本理论,钢筋混凝土结构可靠指标的计算方法及其计算公式.同时利用所编制的相应计算软件RCPA,结合工程实例对钢筋混凝土非杆系结构进行了可靠指标的计算,并分析其可靠性,从而为判断结构的尺寸、配筋是否合理提供可靠度依据.
Combining the stochastic finite element method (SFEM) with the nonlinear behavior of reinforced concrete, the general theory of reliability analysis of reinforced concrete massive structure by SFEM is discussed and formulas of reliability indexes are derived. Meanwhile, the corresponding computational program RCPA is applied to an example of analysis and computation of reliability indexes of reinforced concrete massive structure so as to provide reliability basis for judging the rationality of the dimensions and reinforcement of the structure.
