［摘要］2010年世博会大明宫馆是一座传统风格建筑，为结构形式独特的展馆。采用钢-木组合结构，底部1层为钢结构，上部2层为木结构。基于大明宫馆建筑风格和使用特点，介绍了结构选型、结构布置、结构分析及关键节点构造等。结果表明：钢-木组合结构有利于实现该特定建筑的造型和功能要求。通过木结构卯榫和钢结构螺栓连接实现建筑的工业化、装配化，满足了世博会展馆需求，实现了异地拆卸重建目标。在继承传统建筑风格的基础上，运用现代建筑结构材料和结构体系，创造建筑空间、达到设计目的，确保了工程的可逆性和安全性。结构选型思路和关键节点设计方法可为类似工程的分析和设计提供设计参考。

Abstract:Daming Palace in World Expo in 2010 is a traditional style architecture with a unique structure form. It adopts steel-wood composite structure, with the bottom layer of steel structure and the upper two layers of wood structure. Based on the architectural style and functional characteristics of Daming Palace, the selection of the structural system, the layout of the structure, the analysis of the structure and the construction of the key joints were introduced. The results show that the steel-wood composite structure is beneficial to realize the shape and functional requirements of the particular building. The tenon of wood structure and bolts connection of steel structure realize the industrialization and assembly of the building, which meets the needs of World Expo Pavilion and realizes the goal of off-site demolition and reconstruction. On the basis of inheriting the traditional architectural style, modern architectural materials and structural system are used to create architectural space, to achieve the purpose of design, which ensure the reversibility and safety of the project. The structural system selection method and key joint design method can provide reference for the analysis and design of similar projects.

Keywords:traditional style architecture; steel-wood composite structure; structural system selection; structural design
