摘　　要：某幼儿园–综合楼项目,采用了粘滞阻尼器进行结构减震设计。借助有限元软件SAP2000建立原始结构模型,并和盈建科模型进行对比校核,模型精度满足要求。挑选地震波输入模型,采用时程分析法加以研究,分析其在小震弹性和大震下弹塑性下结构的抗震消能情况。结果表明:结构在安装粘滞阻尼器后,各项抗震指标均在规范要求范围之内,地震能量消散情况较好,结构抗震性能有效提升,增强了结构安全性。A kindergarten–comprehensive building project adopted a viscous damper for structural damping design.The original structural model is established by finite element software SAP2000,and compared with YJK model,the accuracy of the model meets the requirements.The seismic wave input model is selected,and the time–history analysis method is used to analyze the seismic energy dissipation of the structure under the small earthquake elasticity and the large earthquake elastoplasticity.The results show that after the viscous dampers are installed,the seismic indexes of the structure are within the range of the code requirements,the dissipation of seismic energy is better,the seismic performance of the structure is effectively improved,and the structural safety is greatly enhanced.
