摘要
基于满足设防烈度地震作用下正常使用的抗震性能要求,对成都市东部新区一栋多层框架结构的医院建筑,采用了消能减震技术,应用黏滞阻尼器进行减震分析。简要介绍了黏滞阻尼减震技术的设计方法,通过对比在小震、中震、大震三水准地震作用下的计算结果,得出了设置黏滞阻尼器可以满足预期的设防烈度地震作用下正常使用的性能目标要求,为类似的工程实例提供设计参考。
In order to meet the seismic performance requirements of normal use under the action of fortification intensity earthquake,a multistory frame hospital building in the eastern new district of Chengdu was analyzed with the application of viscous damper and energy dissipation technology.The design method of viscous damping technology was briefly introduced.By comparing the calculation results under the three level earthquakes of small earthquake,medium earthquake and large earthquake,it is concluded that setting viscous damper can meet the performance target requirements of normal use under the expected fortification intensity earthquake,which can provide design reference for similar engineering practice.
