某教学楼框架结构的黏滞阻尼器减震加固设计

Seismic Retrofit Design of a Teaching Building with Frame Structure by Using Viscous Field Damper

介绍了位于抗震设防烈度Ⅶ度区的某中学6层教学楼所采用的黏滞流体阻尼器的消能减震加固的计算和设计.该教学楼为现浇混凝土框架结构,考虑到其建筑使用功能和抗震要求,在1～6层优化布置了52套黏滞流体阻尼器,时程分析结果表明：黏滞流体阻尼器可大量耗散地震动能量,显著降低了结构的地震响应.

The calculation and design of energy-dissipated seismic retrofit of a 6-story teaching building in a middle school located in seismic fortification intensity of Ⅶ by using viscous fluid dampers is introduced.The structure of the teaching building is the cast-in-situ concrete frame.Considering the using function and seismic performance demand of the building,the teaching building is optimally arranged 52 viscous dampers from the first to the sixth story.The dynamical time history analysis results indicate that the viscous fluid dampers effectively dissipate the energy of structure vibration and obviously reduce the seismic response of the structure.
