大层高框架结构模型振动台试验

某些大型公共建筑进行抗震加固时由于建筑使用功能的要求难以采用传统加固方式,采用消能减震加固时,可能仅在部分楼层增设阻尼器。主要针对某框架结构的大型公共建筑仅在薄弱层增设黏滞阻尼器进行模型振动台试验,并对模型在地震作用下的地震响应及动力特性进行对比研究。试验结果表明,在薄弱层增设黏滞阻尼器可有效地控制、降低结构的地震反应。

SHAKING TABLE TEST ON A LARGE STORK HEIGHT MOMENT FRAME

Due to the architecture function restriction,it is difficult some large scale public buildings to use the traditional strengthening methods,hence only partia stories could be equiped with dampers when using energydissipation method. This paper concentrates on a shaking table test of a moment frame structure public building model. This structure only installed the viscous dampers can be installed only on weak layers. This paper compared the seismic response and dynamic character of the model with and without damper. The test result shows that installing the viscous damper on weak layer is effective in controlling and decreasing seismic response.
