摘要
论述了抗震设计的反身性和决定构件抗震性能的三个方面,以及按照GB 50017-2017《钢结构设计标准》第 17章的钢结构建筑抗震设计方法,对结构性能系数给出了短周期调整、多自由度放大、二阶效应放大和阻尼调整系数.介绍了延性开展机构的控制及其与机构控制等效的方法,对高层多自由度结构的底部加强区地震作用调整引入了新的解释,最后接受了地震作用组合下的二阶分析设计法.
Abstract
Seismic design has the characteristic of self-fulfillment.Seismic behavior of members depends on three aspects:capacity,ductility and plumpness of hysteretic curves.Method for seismic design to standard GB 50017-2017 is introduced.For system performance factors the required modifications incorporating effects of short period,MDOF,second order effect and damping are introduced.The control of ductility development mechanism and its control method are introduced.A new explanation is provided for the enlargement of seismic effect in the bottom stories,finally the design technique of second-order analysis used for seismic design is discussed.
