分析了钢支撑的滞回曲线特征和破坏机制，提出了钢支撑非线性模型的模拟方法，并对现象学模型、塑性铰模型和有限元模型的概念及特点进行了论述，以根据不同的建筑规模，选择合适的钢支撑恢复力模型。%The paper analyzes the features of hysteretic curve and damage mechanism of the steel support,points out the simulation methods for the non-linear model of the steel support,and indicates the concepts for the models of phenomenology,plastic hinge and finite element,so as to elect suitable steel support resilience according to various architectural scales.
