相邻结构连接粘滞阻尼器减震效果的振动台试验研究
Shaking Table Test on Adjacent Structures Connecting with Viscous Dampers
摘要
Abstract
Using a 15-and 7-stroyed frame-shear wall model with 1/20 measuring scale,the shaking table tests were performed to explore the vibration reactions at three positions of the structure with two viscous damper connections under 7 degree with four levels of seismic action including frequent,design,rare and large earthquakes.The results show that under the 7-degree frequent and design earthquake actions,the damper connections have certain control effects on the structural seismic reactions,while the control effects of shear force reactions are relatively bad;under the 7-degree rare and large earthquake actions,the damper connections have less control or even increase in the seismic reactions of the main structure with most increase instead of decrease in the reactions of the substructure;under the 7-degree frequent and rare earthquake actions,the maximum drift angle of the structural interlayer may meet the objective requirements of the seismic performance;the damping effects are better as the damper connections on the top of substructure or between the top and the first storey,with the weak positions at some parts (the bottom storey,the altitude directional inter-storey,the several storey near the top) of the main structure and the bottom storey of substructure.关键词
