云南某康复中心减震设计分析

Analysis of seismic mitigation design of a rehabilitation center in Yunnan

以一栋框剪结构建筑为例,利用粘滞阻尼器进行消能减震设计。采用YJK软件确定其达到目标位移值所需的消能减震器参数和数量,之后使用SAP2000软件建模并附加非线性阻尼单元,对结构输入7条地震波对比分析消能减震设计前后的抗震性能。结果证实,利用附加粘滞阻尼器可使结构具有良好的耗能能力,提高抗震性能并达到抗震设防目标。

A box-shear structure is used as an example for the design of energy dissipation and damping using viscous dampers. The YJK software was used to determine the parameters and the number of energy dissipation dampers required to achieve the target displacement value,and then the SAP2000 software was used to model the structure with additional nonlinear damping units,and seven seismic waves were input to the structure to compare the seismic performance before and after the energy dissipation damping design. The results confirm that the use of additional viscous dampers can make the structure have good energy dissipation capacity,improve the seismic performance and achieve the seismic prevention target.
