摘要
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 design of a high-rise hospital building with non-linear viscous dampers was introduced,including the layout of dampers and the selection of seismic waves. Finite element simulation of the high-rise frame-shear wall structure was studied. The elastic time-history analysis of the structure under frequent earthquakes was carried out by using ETABS software,and the elastic-plastic time-history analysis of the structure under rare earthquakes was carried out by using SAP2000 software. The results of the time-history analysis under three different seismic waves were compared and it is found that the seismic behavior of the building was improved by using the damping structure with non-linear viscous dampers.
