采用被动控制的四塔连体结构振动台试验研究
Shaking table test of four-tower connected structure with passive control
摘要
Abstract
A 235 meters high four-tower structure is inter-connected with 300 meters long sky corridor bridges on the top floor.To reduce the earthquake responses and member forces of the towers and sky corridor,passive control strategy was adopted.The connection between the towers and sky corridor were designed as flexible links,where friction pendulum bearings and viscous dampers were installed.To study the seismic performance of this complex structure,a 1/25 scaled model structure was tested on shaking table.Results show that the four-tower connected structure with passive control strategy can meet the seismic resistance design requirements.The friction pendulum and viscous damper perform very well for seismic isolation.The sky corridor elements still remain elastic state under the rare earthquake levels.关键词
