摘　　要：介绍了西安曲江国际会议中心40m跨型钢混凝土转换桁架的分析与设计过程,阐述了型钢混凝土转换桁架的设计要点。通过对四种不同腹杆布置方式转换桁架受力特点的对比分析,得出X形+竖杆这种腹杆布置方式的转换桁架适用于此超大跨度的转换结构。对转换桁架下部支撑结构的计算分析表明,将其设计为内藏钢桁架的混凝土剪力墙形式,既能保证其具有足够的承载力,又具有较好的延性。The analysis and design process of the 40m span steel-reinforced concrete transfer truss of Xi＇ an Qujiang International Congress Center were introduced as well as the main design features. By comparing the stress characteristics of four different arrangements of web members of transfer trusses, the transfer truss with web arrangements of X-shaped and vertical members are applicable to such long-span transfer structure. The calculation and analysis of the support structure of the transfer truss show that the concrete shear wall with inner steel truss can guarantee the support structure to have enough bearing capacity and good ductility.
