［摘要］鄂尔多斯青铜文化博物馆因建筑功能、外观造型的要求，采用了内筒（钢筋混凝土框架-剪力墙）-外挑钢桁架的混合结构体系，并在设计中使用多种结构计算程序对其进行计算分析。通过对结构方案、结构计算、混凝土与钢结构之间的连接等论述，介绍本工程的特点及计算分析等。其中重点分析了环形平面布局建筑物的环箍力的特点、不同材料与体系之间的共同作用、协调变形等；解决了建筑物各层重心偏移过大、外挑钢桁架与混凝土筒体的连接等工程难点问题。

Abstract: Due to the requirements of construction features and outward appearance, Ordos Bronze Culture Museum has used the composite structure system composing of reinforced concrete tube and steel trusses. The structure was analyzed by several structural design programs. Through the discussion of structural plan, structure calculation and connections between concrete and steel, project features and calculation analysis were introduced. Hoop stress characteristic of ring-like planar configuration buildings, combined actions and co-deformation between different materials and systems were focused. The project difficulties were solved such as oversized displacement of each floor’s gravity center and connections between steel trusses and the concrete tube.

Keywords: composite structure; gravity center; hoop stress; structural design
