摘要
介绍了一种适用于钢结构塑性分析的新的双曲面本构关系模型,可有效地考虑加载历史的影响,对于非比例加载有良好的适用性,可用于钢结构在复杂动力荷载作用下的塑性分析,在分析中不会引起数值计算中的困难。计算实例证明,该模型是精确和可靠的。
Based on Zieglers kinematic hardening model, a new hyperboloidal constitutive model which is suitable for the plastic analysis of steel structures is presented. The model is not only capable of considering the effect of loading history, but also applicable to unsymmetric plastic cycle of strain. Thus, it can be used to perform plastic analysis of steel structures under complex dynamic load. Using this model, the response of steel structures under severe earthquake action can be traced efficiently. Numerical examples demonstrate that the model has enough precision and reliability and it can be implemented easily in computer analysis.
