摘要

某大型商业中心抗震设防烈度为8度,结构体系为方钢管混凝土柱+钢框架梁,采用黏滞阻尼器进行消能减震。主要阐述了该大型商业综合体消能减震设计的阻尼器布置、有效附加阻尼比计算、小震弹性时程分析和减震率分析、大震弹塑性分析及加强措施。结果表明,结构各项指标均能满足现行规范及规程要求,大震下黏滞阻尼器的减震耗能效果明显,有效保护了主体结构,提高了整体结构的抗震性能。
        A large commercial center is located in region of 8 degrees of seismic fortification intensity,and it adopts structural system of concrete-filled steel square tube column + steel frame beam.Viscous damper is adopted for energy dissipation.Designs and analysis of this large-scale commercial complex were mainly elaborated including the damper arrangement for energy dissipation design,effective additional damping ratio calculation,elastic time-history analysis and shock absorption rate under frequent earthquake,elasto-plastic analysis and strengthening measures under rare earthquake.The results show that all the indexes of the structure can meet the requirements of current codes and regulations.The energy dissipation effect of viscous dampers under rare earthquake is obvious,which effectively protects the main structure and improves the seismic performance of the whole structure.
