大跨度木结构蒙古包的设计与工程实践

Design and Engineering Practice of Large-Span Wooden Structure Yurts

在我国“双碳”目标的实现和新时代中国民族建筑复兴的背景下,木结构建筑市场再次兴起。在原民族建筑文化内涵的基础上对结构进行创新,以满足现代市场的需求已成为新的研究方向。本文针对希拉穆仁草原景区设计了一座大跨度蒙古包,在不改变建筑材料的基础上,采用木网壳结构体系对传统建筑结构进行创新与优化,其最大跨度为23.5 m,最大高度为11.5 m,且整体结构稳定。在此基础上,利用有限元软件进行建模,对可能出现的各种工况进行静力计算和屈曲分析,验证了该结构的可靠性。本研究对我国大跨度木结构的发展和传统木结构建筑的创新具有重要的借鉴意义。

In the context of the realization of China's"dual carbon"goal and the revival of Chinese ethnic architecture in the new era,the wooden structure building market has once again emerged.Innovating the structure based on the cultural connotations of original ethnic architecture to meet the needs of modern markets has become a new research direction.In this article,a large-span yurts in the Hilamuren Grassland Scenic Area was designed.Without changing the building materials,the traditional building structure was innovated and optimized using a wooden mesh shell structure system,which also exhibited structural stability with a maximum span of 23.5 m and a maximum height of 11.5 m.On this basis,finite element software was used for modeling,and the static calculations and buckling analysis were also conducted for various possible working conditions.The results verified the reliability of designed structure.This study had important reference significance for the development of large-span wooden structures and the innovation of traditional wooden structures in China.
