超大跨维修机库地震响应采用不同被动控制方法的研究
|
摘要
大跨维修机库动力特性复杂,针对该类结构的减震研究则刚刚起步。本文结合大跨机库的水平地震响应特点,分别选取了布置柱间消能支撑、柱顶橡胶隔震支座两类被动控制方案,分别研究不同减震方法对机库结构水平、竖向地震作用下相应方向上地震响应减震的可行性。通过对比各减震方法下机库结构基底剪力、柱顶位移以及屋盖杆件内力、节点响应的减震效果,分析了各减震方案的优缺点。研究结果表明,通过合理地设置减震装置,采用本文被动控制技术可以很好地降低机库结构水平方向的地震响应。
The dynamic characteristics of long-span hangar are very complex and shock absorption study on this type structure is just started.Combining with seismic response characteristics,two shock absorption methods are proposed including setting fluid viscous dampers between columns and joints of the roof,column cap seismic isolation. Feasibility study of different methods for the seismic response of the hangar under earthquake input from different directions is carried out.Comparison results of base shear,lateral displacement of column cap,inner force of space-frame poles and displacements of joints in the roof show the advantages and disadvantages of every method and they can effectively decrease the seismic response by setting reasonably.
