| This paper describes the developed history and status of Chinese wooden buildings and overseas wooden buildings. The architectural forms,characteristics,connective forms of the ancient wooden structure and the kinds of mortise-tenon conncetion have been carried a detailed analysis.The structure mechanism and stress principium of the mortise and tenon is analysed based on the characteristic of wooden material by this paper.Throuh a wooden structure model experiment, the four-factor exponential function related curves of the moment-deflection angle is found. The nonlinear stiffness matrix of the mortise-tenon connection is deduced , and making an static analysis to the town and village wooden buildings of YunNan province. In accordance with the mechanics behavior of mortise and tenon joints,Ruili damped matrix model of planar wooden structure frame is acquired. By the program maked with Matlab, the dynamic behavior and aseismic mechanism of the mortise-tenon structure are indicated in the time-history analysis of the planar wooden structure frame. |
