Researches on Seismic Response Reduction of Additional Viscous Damp Elevated Vertical Cylinder Storage Tanks
摘要
Abstract
By installing the viscous damper in elevated vertical cylinder storage tanks that is to reduce the damage caused by the earthquake.The simplified mechanical model and finite element numerical simulation model of top isolation elevated vertical cylinder storage tanks are established and the seismic response of ground motion is studied from two aspects of theoretical research and finite element numerical simulation analysis.The result was indicative:The viscous dampers are applicable and the seismic response of the structure is obviously reduced,especially that can control the liquid sloshing height in a certain extent.The damping efficiency of viscous dampers is closely related to the velocity index and selection of speed index should not be too large or too small,if the velocity index is too large,it may lead to the failure of the damper and the structure connection,which makes the damper failure,when the velocity index is too small,the control function of the structure is limited,and the story drift ratio is larger.The theoretical solution and the finite element solution are close to each other,which verify the accuracy of the results.According to the actual situation of the project,the design of viscous dampers should consider two factors of structural safety and economy and choose the best viscous damper configuration.关键词
