摘要
通过对一钢筋混凝土简支梁的有限元分析,探讨了损伤塑性模型在混凝土非线性分析中的应用方法、技巧及应注意的问题,并采用参数分析,研究了混凝土膨胀角、受拉硬化、受拉损伤变量等参数对计算结果的影响,为进一步将该模型应用于钢筋混凝土结构精细非线性有限元分析提供了参考。
By the analysis of a simply supported reinforced concrete beam, the using method, skills and considerations of the damaged plasticity model for concrete were discussed at length. Using parametric analyses, effects of the dilatation angle, tension stiffening, tension damage factor etc on the result were studied. Some valuable advices were promoted for accurate nonlinear finite element analysis in reinforced concrete structures using this model.
