新型间隙式黏滞阻尼器对钢筋混凝土框架结构的减震效果试验研究
|
摘要
本文通过钢筋混凝土框架结构附加黏滞阻尼器的振动台试验,考察了两种新型间隙式黏滞阻尼器对结构的减震效果。通过试验数据分析可以看出,安装了黏滞阻尼器的结构在峰值响应和整个时间历程上的响应都有比较明显的降低,说明了新型间隙式黏滞阻尼器作为减震耗能装置,能够帮助结构消耗大量的地震能量,具有良好的应用前景。此外,通过对梁柱节点的应变分析得知,斜撑式的阻尼器支撑会对与其直接相连的梁柱节点附加一定的额外负担,因此在减震设计中应给予充分的重视。
In this paper,the damping effect of a new type clearance viscous damper is investigated by a series of shaking table tests of RC frame structure equipped with the viscous dampers. Trough the analysis of test data,it is observed that the peak and the whole time history responses of the structure equipped with viscous dampers are significantly reduced,this can illustrate that the new type of viscous damper,as a vibration energy dissipation device,can help the structure to dissipate a large amount of earthquake energy and has a good application prospect. Besides,through the analysis of the strain of the beam-column joints,it is observed that the diagonal damper brace may impose additional burden on the beam-column joints which are directly connected with the brace,This should be paid full attention.
