摘要
分别考虑了钢材和混凝土的非线性性能,在开源软件OpenSees的平台上,采用纤维截面模型对钢骨混凝土受弯构件进行非线性有限元分析,并将计算结果与相关的试验结果进行了对比分析。分析结果表明:本文采用的纤维模型得到的计算结果与试验结果比较吻合,验证了在OpenSees的平台上,选择合理的本构及计算参数的纤维模型分析钢骨混凝土梁的可靠性。
Taking into account the non-linear behavior of steel and concrete, this paper uses the analysis software OpenSees to make finite element analysis on steel reinforced concrete beam by means of the fiber section model and compares the calculation results with the corresponding experimental results. Analysis results show that the calculation results of fiber model agree with the experiment, which verifies the reliability of the analysis on steel reinforced concrete beam by uses of fiber model with reasonable constitutive relationship and parameters based on OpenSees.
