广东科学中心E区结构模型振动台试验研究
|
摘要
为了检验广东科学中心建筑结构的抗震性能,采用1∶35的比例制作了E区结构的缩尺模型,在三向六自由度大型模拟地震振动台上进行了试验,研究了模型结构的自振特性、阻尼比、地震反应特征,并分析了原型结构的地震反应性能。
In order to investigate the seismic performance of Guangdong science Centre,a model of area E in Guangdong science Centre with scale of 1∶35 is fabricated and tested on the large-scale shaking-table with 3 dimensions and 6 degrees of freedom.Based on the test,the self-shaking properties,damping ratios,seismic responses are investigated,and the seismic responses of the prototype structure are analyzed.
