双段消能摇摆钢框架结构抗震性能影响因素与设计方法
Influencing Factors and Seismic Design Procedure of Steel Frame Coupled with Dual-rocking Structure
摘要
Abstract
In this paper,a systematic parametric study is conducted to investigate factors affecting the seismic performance of steel frame coupled with dual-rocking structure(DRF).Design requirements are proposed based on the Chinese code for the seismic design of buildings.Firstly,a simplified analytical model for DRF is introduced and validated through elastic-plastic seismic response analysis.Subsequently,dimensionless parameters affecting the seismic response of DRF are identified and optimal value range is determined through parametric studies of the simplified analytical model.Finally,a seismic design procedure for DRF is proposed and validated through numerical examples.It is shown that the seismic performance of DRF under maximum considered earthquake is satisfactory.Rationally designed dual-rocking steel frames exhibit significantly reduced internal forces within structural components compared to single-rocking steel frames.When coupled with dampers,dual-rocking steel frames can suppress weak stories and mitigate seismic responses,demonstrating practical engineering feasibility.关键词
