摘　　要：某不规则多层长途汽车站工程主要由长途客运站、公交首末站、换乘连廊及站台雨棚组成。长途客运站主体结构采用框架-剪力墙结构+张弦梁屋盖。换乘连廊采用单排柱柱顶铰接的排架结构。主要介绍了具有多排斜柱、扭转不规则、楼板大开洞、凹凸不规则等多项不规则的长途客运站的抗震性能设计、屋面张弦梁结构设计;分析了钢箱梁+钢筋混凝土Y形分叉柱的换乘连廊的结构特点;剖析了钢箱梁考虑剪力滞效应和受压局部稳定影响的有效截面宽度的计算及Y形分叉柱与横梁、Y形分叉柱柱墩支座选型的设计要点。分析结果表明,所采取的合理结构设计确保了结构安全。The project of an irregular multi-story long-distance bus station mainly consists of long-distance passenger station,the first and last stops of buses,the transfer corridors and the platform canopies.The main structure of long-distance passenger station adopts the frame-shear wall structure+the roof with stringed beams.The transfer corridors adopt the bent structure with hinged top of single-row columns.The seismic performance-base design of the long-distance passenger station with many irregularities such as multiple rows of inclined columns,torsional irregularities,large openings in the floor slab,and concave-convex irregularities was mainly introduced,as well as the structural design of the roof stringed beams.The structural characteristics of the transfer corridor with steel box girder+reinforced concrete Y-shaped bifurcated columns was analyzed.The calculation of the effective section width of the steel box girder considering the shear lag effect and the influence of local stability under compression was dissected,as well as the design key points of Y-shaped bifurcated column and cross beams and bearings selection of the Y-shaped bifurcated columns piers.Analysis results show that reasonable structural design adopted ensure structural safety.
