摘　　要：上海某教学综合楼为特别不规则结构,存在平面楼板局部不连续、凹凸不规则、扭转不规则等抗震不利因素,如按常规设计框架梁柱截面较大且配筋困难,整体指标难以满足,故采用了消能减震技术。结合项目实际,阐述了支撑型金属抗震阻尼器在结构设计中的具体应用。重点给出了消能减震方案弹性计算分析设计流程,采用YJK对结构进行反应谱分析和小震弹性时程分析,采用MIDAS对结构进行大震弹塑性时程分析。A teaching complex building in Shanghai has a particularly irregular structure,with locally discontinuous floor slabs,irregular bumps and turns,and other seismic unfavorable factors.For example,according to conventional design,the beam column section of the frame is large and the reinforcement is difficult,making it difficult to meet the overall indicators.Therefore,energy dissipation and seismic reduction technology was adopted.This article elaborates on the specific application of supported metal seismic dampers in structural design,based on the actual project situation.The focus is on providing the elastic calculation analysis and design process for energy dissipation and seismic reduction schemes.YJK is used to conduct response spectrum analysis and small earthquake elastic time history analysis on the structure,while MIDAS is used to conduct large earthquake elastic-plastic time history analysis on the structure.
