［提要］建筑在造型上的不断创新，空间构成的变化，使得结构设计理念发生了重大变革，特别是中庭空间的出现和底部空间的变化对结构的实现提出了更高的要求，要求结构形式不断创新。广东省博物馆新馆为满足建筑方案对空间的要求，采用了钢桁架对挑悬挂结构这一种较为新颖的结构体系。结合广东省博物馆新馆结构设计，介绍了该结构形式的结构布置特点，工程结构设计中内置钢管混凝土剪力墙、矩形钢管混凝土桁架、内置加气混凝土楼板及减振措施等关键技术。就设计方案的选取、计算软件的选取、设计中致力解决的问题和一些新技术的采用等提出了一些看法，以供交流。

Key Techniques of Structure Design in Guangdong Province Museum/Chen Xing, Wang Hualin, Li Na (The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010, China)

Abstract:The unceasing model innovation and spatial constitution change lead to renovation in the structural design concept, especially the appearance of atrium space and the base stories space call for more critical requirement to structural engineers as well as innovative structural systems. For satisfying the architect"s spatial request, a unique structure system, large span overhang steel trusses with suspension floor, is adopted in Guangdong Province Museum. The structural arrangement, some key points in the design including schemes selection, analysis software selection, the problems to be solved during design and the application of new technique, are mentioned briefly. Some views about suspension structure are proposed for exchange.
