摘　　要：由于建筑立面效果和使用功能的需求,某公交场站采用板-柱结构体系。该工程由三种尺寸的“伞单元”错落、组合而成,最大伞单元尺寸为17200(长)×15200(宽)×1750(厚),单侧悬挑8600mm,上覆600mm厚覆土,悬挑大、荷载重、结构单元新颖。采用YJK和MIDAS Building两种不同的力学模型软件进行多遇地震的比较分析,经过精细建模后两者计算结果基本一致;并补充弹性时程分析和罕遇地震下的静力弹塑性分析,确保结构各项指标参数均满足规范要求。采用抗震性能化设计,对关键构件进行抗震性能分析和构造措施加强。另外采用MIDAS Gen及ABAQUS软件进行楼板的舒适度分析及有限元精细化分析,计算结果表明结构舒适、安全可靠。Due to the requirements of architectural facade effect and functional usage,a bus station adopts slab-column structure system.The project is composed of“column caps”in three different sizes,arranged and combined in a staggered manner.The largest column cap measures 17200(length)×15200(width)×1750(thickness),with a cantilever of 8600mm on one side.It is covered with 600mm thick soil on top,making it a unique structure unit with a large cantilever,heavy load,and innovative design.A comparative analysis of frequent earthquakes was conducted by using two different structural analysis software,YJK and MIDAS Building.After refined modeling,the calculation results from both software are consistent.In addition,elastic time history analysis and static elastic-plastic analysis under rare earthquakes were supplemented to ensure that all structural indicators meet the current code requirements.The seismic performance-based design was adopted to carry out seismic performance analysis of critical components and strengthening structural measures.The comfort analysis and refined finite element analysis of the floor were carried out by MIDAS Gen and ABAQUS,the results of calculation show that the structure is comfortable,safe and reliable.
