强震下隔震结构碰撞地震响应分析
Seismic Response of Isolation Structure Considering Impact under Strong Earthquakes
摘要
Abstract
Considering the effect of impact between structures under strong earthquakes to isolation structures,this paper analyzed an 8-story structure in Perform-3D.The results show that the isolation effect will be weaken once the isolation structure impacts with others.The displacement of isolation layer is proportional to the peak value of acceleration,while is inversely proportional to the impact stiffness.Secondly,the impact of structure will lead to enlargement of plastic dissipation of structure.Besides,the impact will increase the story drift of a structure.The more severe a structure impacts,the more obvious the structure vibrates.As to the acceleration of the structure,the response caused by impact is dependent on the response of seismic waves.The response of a structure will increase with the impact stiffness when the response of the seismic wave is small.While under strong earthquakes,there is no definite conclusions to the response of superstructures.关键词
