凉山彝族瓦板房民居搧架结构优化设计研究

Study on wooden Shan-jia structural of the tile board house residence of Yi Minority in Liangshan

木构搧架是彝族瓦板房民居的主要承重结构,也是其最具特色且最具有保护价值的民居要素之一。本文收集了三种典型的搧架结构布置方案,通过ANSYS软件进行结构计算,发现各种布置形式的结构薄弱环节和受力弱点;最后提出优化设计的措施,以达到提高建筑的抗震性能和改良瓦板房的建造工艺的目的。

The wooden Shan-jia structure （The braced arch structure） ,the main load-bearing structure in the traditional tile board room of Yi Minority, is one of the residentiul elements which are most distinctive and most valuable to be protected. As the traditional architectural culture of the Yi,the structure is still being widely used in local residence, but the Liangshan Yi Minority is located in high intensity earthquake zone,which cause large security risks on the wooden frame system, in this paper,three kinds of common and typical layouts of braced arch structure are collected after investigating of the wooden Shan-jia structure. The structural weaknesses are found through the simulation of ANSYS. Finally, propose some measures to optimize the structural design, in order to enhance the seismic optimization and improve the construction technology of tile board room.
