【摘要】 为了检验广东科学中心E区在地震作用下的结构性能,采用1:35的比例制作了缩尺模型,在广州大学抗震中心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。试验结果表明,采取隔震措施,可以明显改善结构的抗震性能,对于平面不规则结构,更能改善结构的抗扭性能,提高结构的抗震安全性。更多还原

【Abstract】 In order to investigate the seismic performance of area E in Guangdong science Centre,a model with scale of 1:35 is fabricated and tested on the large-scale shaking-table with 3 dimensions and 6 degrees of freedom in the seismic center of Guangzhou University.Based on the test,the self-shaking properties,damping ratios,seismic response are researched,and the seismic response of the prototype structure is analyzed.It is shown that satisfactory seismic performance of the structure can be improved if seismic isolation measures were taken. Especially for irregular plan structure,torsion of the structure can be improved obviously,and the structure will exhibit satisfactory seismic performance.更多还原
