[摘要] 重庆两江鱼嘴汽车博物馆采用钢框架形式。本工程特点是平面开洞面积较大，存在跃层构件，屋面为大跨度结构。对该结构的一些技术难点进行分析，采用两个不同计算模型对该结构进行对比分析，梁柱连接节点采用板壳有限元对节点进行详细分析，对结构的可靠性做出判断。

Abstract: Steel frame structure is adopted for automobile museum of Fish Mouth Motown in Chongqing. There are large structural opening, columns that jump structural floor and long-span structural roof in the project. Structural technological difficulty was analyzed in the article. Analysis of two different calculation model was compared. Shell finite element of joint of beam and column was established to analyse. Safety of structure was estimated.

Keywords: steel frame; columns that jump structural floor; arch steel truss; beam-column joints
