大跨悬挑屋面的设计与研究

Design and Research of Large-Span Overhanging Roofs

随着国民经济的快速发展,钢结构建筑也正在向着多用途、多功能的方向变革。基于钢结构较混凝土结构更容易满足城市美观与功能的双向需求,因此钢结构建筑物也日益增多。本文基于某公建大跨悬挑屋顶的设计实例,从方案选型、受力分析及重难点分析3个方面进行了设计研究。采用同济大学3D3S有限元软件对结构进行有限元计算,采用Midas Gen软件进行复算。通过本文的设计分析,为以后的设计工作提供参考。

With the rapid development of the national economy,steel structure buildings are also transforming towards the direction of multi-purpose and multi-function.Based on the fact that steel structures are easier to meet the dual needs of urban beauty and function than concrete structures,steel structure buildings are also increasing.Based on the design example of a large-span overhanging roof of a public building,this paper conducts design research from three aspects:scheme selection,force analysis and analysis of major difficulties.The 3D3S finite element software of Tongji University is used to calculate the structure,and the Midas Gen software is used for the re-calculation.Through the design analysis in this paper,it provides reference for future design work.
