广州市档案馆新馆档案库房采用钢筋混凝土框架(局部无梁楼盖)+耗能支撑结构体系,结构设计使用年限为100年,建筑抗震设防类别为乙类,抗震等级为二级。引入基于性能的抗震设计方法,利用快速非线性时程分析方法对结构进行计算。结果表明,通过增设粘滞耗能支撑可以明显地降低结构的加速度、位移和内力反应,大大提高结构的抗震安全储备。在增加很少土建投资的情况下,可实现大震不屈服的性能目标。
The new archives of Guangzhou City archives use a reinforced concrete frame (partial non-beam floor) + energy-dissipating support structure system, and the service life of the structure is 100 years. The building’s seismic fortification category is Class B and the seismic grade is two. The performance-based seismic design method is introduced, and the structure is calculated by fast non-linear time-history analysis. The results show that the acceleration, displacement and internal force response of the structure can be significantly reduced by adding viscous energy dissipation support, which greatly improves the seismic safety reserve of the structure. In the case of a small increase in civil investment, the performance target of the earthquake does not yield.
