钢筋混凝土随机有限元计算软件的开发

Development of computational software of stochastic finite element method for reinforced concrete

在钢筋混凝土随机有限元基本理论和非杆系结构实用设计方法的基础上,利用Fortran语言开发了钢筋混凝土随机有限元应用软件系统.主要介绍了其中计算软件部分的结构设计框架、有关的编制原理及功能特点.借助于该软件,不仅可以对钢筋混凝土结构进行非线性分析,计算在不同极限状态下结构的可靠指标,并可分析随机变量对结构可靠度的影响.

Based on the theory of stochastic finite element method for reinforced concrete and practical design method for massive structure, the corresponding applicational software is developed. The program structure, the coding principle and the computational function of the computational software are mainly introduced. By using this program we can carry out the nonlinear analysis of reinforced concrete structure, calculate reliability index relative to different limit-state criterions, and also can analyze the effect of random variables on the reliability of a structure.
