与抗震设计有关的结构和构件的分类及结构影响系数
|
摘要
根据近年对延性、阻尼、后期刚度、耗能能力、滞回曲线形状、2阶效应等因素对单自由度体系在地震作用下弹塑性响应影响的分析,提出一个比较完整的面向地震力计算和抗震设计的抗侧力体系、构件、连接节点和截面的分类体系,并与结构影响系数相联系。为与现行的小震地震力概念协调,又能够考虑钢结构延性好,对地震作用的削减更大的特点,引入地震延性调整系数,与结构和构件的分类配套应用。
Based on the analysis of ductility,damping,post-yield stiffness,energy-dissipating capacity,hysteretic curve shape,effecting on SDOF system under seismic,a systematic classification of earthquake-resistant structures,members,sections and structure influence coefficient closely related to the classification were proposed.For coordinating to concept of minor shock seismic force,and considering good ductility of steel structure,much cutting to seismic action,seismic ductility adjustment coefficient was introduced and supported to classification of structures and members.
