| 摘 要： | 基于经典塑性模型与连续损伤模型,根据广义应力空间塑性力学确定了塑性变形的演化法则,文中发展了一种地震塑性损伤分析方法。用来进行混凝土框架结构的抗震分析,将塑性损伤的本构关系运用于两端具有塑性铰的梁模型,模拟框架结构的梁柱。同时该方法的损伤指数可以确定结构各单元和整体的地震时性能,确定结构极限荷载,算例表明该方法具有可靠的精度。

| Abstract: | A seismic plastic-damage analyses method for reinforced concrete frames is developed in this article,based on the classical plastic model and the continuum damage model.The Plastic-damage constitutive law is implemented into a beam model for framed structures,in which these are described by elastic beams and columns with two inelastic hinges at their ends.A damage index is useful in evaluating the state of structural members and a meaningful global damage index for whole structure are introduced.The method ... |
