摘要
为了探究高层垂直循环立体车库抗震薄弱区域,进一步提高其结构稳定性,开展了地震荷载下的高层垂直循环立体车库结构响应特性研究,基于模态分析结果,分别进行了地震荷载下的立体车库结构响应谱分析和时程分析。响应谱分析结果表明,车库整体结构最大位变形发生在顶部,局部最大变形发生在斜拉杆处;时程分析结果表明,车库最大应力都集中在张紧装置固定板与钢架结构横梁连接处。在三种地震波作用下:车库结构X方向最大变形量分别为0.308 0 mm、1.364 9 mm和0.999 8 mm;车库结构Y向最大变形量分别为15.167 0 mm、10.011 0 mm和9.716 2 mm。研究结果对高层立体停车结构设计及高层立体车库推广具有指导意义。
In order to investigate the seismic weak areas of a high-rise vertical circulation garage and further improve its structural stability,the analysis was carried out on the structural response characteristics of the garage under seismic load.Based on the results of the modal analysis,the response spectrum and transient dynamics analysis of the garage under the seismic load were carried out respectively,and the seismic response spectrum and transient dynamics response of the garage structure under the excitation of the seismic response spectrum were obtained.The results of the response spectrum analysis show that the maximum deformation of the garage structure occurs at the top,and the local maximum deformation occurs at the diagonal tie rods.The results of the transient dynamics analysis show that the maximum stresses of the garage are concentrated in the connection region between the fixed plate of the tensioning device and the beams of the steel frame structure.Under the action of three kinds of seismic waves(EL,TH and RH),the maximum deformation of the garage structure in X-direction are 0.308 0 mm,1.364 9 mm and 0.999 8 mm,and the maximum deformation of the garage structure in Y direction is 15.167 0 mm,10.011 0 mm and 9.716 2 mm respectively.
