基于位移法的市政建筑结构抗震设计

Direct Displacement-based Seismic Design of Municipal Building Structure

在概述延性系数法、能力谱法及直接基于位移法3种建筑结构抗震设计方法的基础上,重点讨论了直接基于位移法的市政建筑结构抗震设计过程及工程应用,并通过弹塑性时程分析验证了这种抗震设计方法的可行性与适用性,为市政高层建筑结构抗震设计提供一些参考。

On the basis of seismic design methods of building structure,i.e.summarizing the ductility coefficient method,capacity spectrum method,and direct displacement-based method,the process and engineering application of direct displacement-based seismic design of municipal building structure are mainly discussed,and the feasibility and applicability of this seismic design method are verified through elastic-plastic time history analysis,which also provides reference for seismic design of municipal high-rise building structure.
