| 摘 要： | 对8度区的西安石油宾馆采用粘弹性消能支撑进行减震设计与研究。首先利用时程分析计算原结构在多遇地震作用下的变形，针对原结构不满足抗震要求，采用粘弹性支撑对原结构进行抗震加固；随后阐述了粘弹性阻尼器及消能支撑的设计，简述了阻尼器位置的优化。通过对该宾馆加与不加粘弹性支撑的时程分析，计算结果表明，粘弹性阻尼器可有效降低结构的振动反应，是一种性能良好的消能减震装置。

| Abstract: | Design and study on petrol hotel in Xi＇an city using viscoelastic energy dissipation braces in seismic regions of intensity 8 are briefly outlined. First, the response of structure under normal earthquake design level is calculated with time history method. Considering the structure not satisfied with aseismatic requirement, viscoelastic energy dissipation braces are used for reinforcement. Then, the design of viscoelastic dampers and connected braces are summarized; and the position optimization of viscoelastic damper is presented. The results proved that viscoelastic damper can reduce the vibration response of the structure effectively through the comparison with and without viscoelastic dampers. It is a high-performance energy dissipation device. |
