摘　　要：相较于传统的钢结构抗震设计方法,采用钢结构精细化抗震设计方法时,地震作用效应取值与结构的延性发生更为明确的关联,且板件、构件、结构的分类基于延性,力学概念更为清晰。详细介绍了结构影响系数的计算方法,构件抗震验算方法,板件、构件和结构的分类,并介绍了不同钢结构体系的屈服机制、验算方法以及钢结构抗震性能化设计方法。Compared with the traditional seismic design method of steel structure,when the refined seismic design method for steel structure is adopted,the value of seismic effect is more clearly related to the ductility of the structure,the classification of plate,component and structure is based on ductility,and the mechanical concept is clearer.The calculation method of structural influence coefficient,seismic checking method of component,classification of plate,component and structure were introduced in detail,and the yield mechanism,checking calculation method and seismic performance design method of different steel structure systems were introduced.
