Study on Wooden Shan-jia Structural of the Tile Board House Residence of Yi Minority in Liangshan

摘要

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 residential 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.
