| 摘 要： | 数值模拟是研究结构和构件抗震性能的重要手段之一。本文以一根钢筋混凝土柱的拟静力试验为基础,通过有限元软件OpenSees,采用非线性纤维单元进行了有限元模拟,分析了网格划分、积分点数量的选取对模拟结果的影响。通过分析比较,最后给出相应的合理参数。

| Abstract: | Numerical simulation is one of the important means to study the seismic performance of structures and components.This paper is based on the pseudo-static test of one reinforced concrete column,through the finite element software OpenSees,by using the nonlinear fiber element is simulated by the finite element method.The influence of grid partitioning and the number of points on the simulation results is analyzed.Through the analysis and comparison,the final reasonable parameters are given. |
