    摘要:

    为高效准确地模拟钢筋混凝土柱的地震损伤过程,将混凝土和钢筋单轴损伤本构模型与基于柔度法的纤维梁柱单元模型相结合,建立钢筋混凝土构件地震损伤分析方法。对钢筋混凝土柱的拟静力试验进行模拟分析,发现模拟模型可以较好的地模拟构件的刚度和承载力退化过程。对钢筋混凝土柱的双向加载振动台试验进行模拟分析,结果表明模拟模型可以较好地模拟构件的非线性动力行为和损伤分布情况。此外,所建立模型可以有效模拟构件的地震损伤演化过程,描述构件的薄弱部位,且具有较高计算效率和求解精度,可用于地震作用下建筑和桥梁结构倒塌过程分析。

    Abstract:

    In order to simulate the seismic damage process of reinforced concrete (RC) columns precisely and effectively, the method of seismic damage analysis of reinforced concrete members is established by combining the uniaxial damage constitutive model of concrete and steel bar with the flexibility-based fiber beam-column element model. The quasi-static test of reinforced concrete column is simulated and analyzed. It is found that the simulation model can simulate the degradation process of stiffness and bearing capacity of component with good accuracy. The shaking table test of reinforced concrete column under biaxial loading is simulated and analyzed. The results show that the simulation model can simulate the nonlinear dynamic behavior and damage distribution of component with good accuracy. Furthermore, the established model can effectively simulate the evolution process of seismic damage of components, and describe weak parts of components, and has high computational efficiency and solution accuracy, which can be used to analyze the collapse process of buildings and bridge structures under earthquake action.
