摘要
四川省老年医学中心项目,采用了设置黏滞消能器的消能减震框架结构体系。主要阐述了黏滞消能器的布置原则、附加阻尼比计算、小震弹性时程和减震系数分析、大震弹塑性时程分析和关键部位验算。结果表明,结构各项指标均能满足现行规范及规程要求,大震下黏滞消能器滞回曲线饱满、减震效果明显,消能器的设置有效保护了主体结构,提高了整体结构的抗震性能。
Energy-dissipation frame structure with the viscous dampers are adopted in the design of Sichuan geriatric medical center.Dampers arrangement rules,the calculation of additional damping ratio,elastic time history analysis and damping coefficient under frequent-earthquake,elastic-plasticity time history analysis under rare-earthquake,and the checking calculation of key components were presented.The results show that all the structure indexes meet the requirements of current codes and regulation.Moreover,the hysteretic curve of viscous dampers is full and earthquake-suppressing effect is remarkable.In addition,the setting of energy dissipation devices effectively protect the main structure and improve the seismic performance of the whole structure.
