介绍了某医院高层住院楼采用非线性黏滞阻尼器的消能减震设计,包括阻尼器的布置和地震波的选取。对该高层框架-剪力墙结构进行了有限元分析计算,采用ETABS软件对结构进行了多遇地震作用下的弹性时程分析,并采用SAP2000软件对结构进行了罕遇地震作用下的弹塑性时程分析。对比不同地震波作用下的时程分析结果表明,采用非线性黏滞阻尼器的消能减震结构提高了房屋的抗震性能。
The energy dissipation and damping design of a hospital high-rise residential building using a nonlinear viscous damper is introduced, including the arrangement of dampers and the selection of seismic waves. The finite element analysis of the high-rise frame-shear wall structure was carried out. The ETABS software was used to analyze the elastic time history of the structure subjected to frequent earthquakes. The elasto-plasticity of the structure subjected to rare earthquakes was analyzed by SAP2000 software Time history analysis. Comparing with the time-history analysis under different seismic waves, the results show that the energy dissipation structure with nonlinear viscous dampers improves the seismic performance of buildings.
