［摘要］通過南寧萬達茂室內主題樂園工程實例，闡述了該項目的設計方案，介紹了地基基礎設計特點、下部混凝土結構設計以及屋蓋鋼結構設計；屋蓋鋼結構部分著重介紹了鋼桁架的設計參數、結構穩(wěn)定性分析、移動荷載設計、關鍵節(jié)點的有限元計算、隱蔽焊縫設計。屋蓋鋼結構設計時對于直接承受游樂設備的轉換構件按《游樂設施設計規(guī)范》（GB 8408—2008）進行設計，對屋面桁架按《空間網格結構技術規(guī)程》(JGJ 7—2010)進行設計。對結構設計的相關問題進行了簡要分析，供同類建筑設計參考。
［關鍵詞］南寧萬達茂; 室內主題樂園； 大跨空間結構選型； 經濟性分析； 鋼桁架節(jié)點分析

Abstract:Through the example of Nanning Wanda Mao Indoor Theme Park Project, the design scheme of the project was expound, the design characteristics of foundation，the design of lower concrete structure and the design of roof steel structure were introduced. The steel structure of the roof was mainly introduced to the design parameters of the steel truss, structural stability analysis, moving load design, finite element calculation of key nodes, and concealed weld design. For the steel structure design of the roof, the conversion members that directly bear the amusement equipment were designed according to the Design rules for recreation facilities(GB 8408—2008), and the roof trusses were designed according to the Technical regulations for space grid structure (JGJ 7—2010). A brief analysis of the related issues of structural design was made for reference to similar architectural designs.
Keywords:Nanning Wanda Mao indoor theme park; type selection of long-span spatial structure; economic analysis; steel truss joint analysis
