| 摘 要： | 为了提高钢框架-支撑结构的抗震性能,在对防屈曲支撑和钢框架-支撑结构研究的基础上,采用防屈曲支撑改进普通钢框架-支撑结构,实现在不增加用钢量的前提下,使钢框架-支撑结构的抗震性能达到中震下主体结构保持弹性的效果.提出了这种改进方法的步骤和关键问题,并结合算例,合理设计防屈曲支撑,采用手算和有限元分析软件对其进行抗震验算和动力非线性时程分析,证明了这种改进方法的可行性和有效性.

| Abstract: | In order to bring improve the aseismatic performance of the common concentrically,based on the researches on the buckling-restrained brace and common concentrically braced steel frames,it was adopt to improve common concentrically braced steel frames.,and achieve the seismic fortification goal.Thus aseismatic performance of the main structure was kept elastic characteristic under the middle seism on the condition that the quantity of steel didn't increase.First the method and the steps were listed.Second ta... |
