榫卯節(jié)點(diǎn)木框架抗火性能研究
[Abstract]:The ancient architecture of China is based on wood structure and is an important part of China's cultural heritage. A large number of scholars have studied and expounded the anti-seismic mechanism of mortise and mortise joint. However, there are few studies on the fire resistance of the mortise and mortise joint frame, so a large number of casualties will be caused whenever the ancient buildings in our country encounter fire. In addition, because of the special artistic and humanistic value of the ancient wood structure and the characteristic that it is difficult to recover once it is destroyed, the indirect loss caused by the fire to the ancient wood structure is immeasurable. Based on the classical theory of heat transfer and the basic principle of finite element, the thermal structure coupling model of mortise and mortise joint wood frame is established by the finite element software ABAQUS. The temperature distribution of the cross section and the fire limit of the frame are analyzed. The main contents can be divided into the following parts: (1) first, it is reviewed and summarized. The domestic and foreign scholars on the main work and achievements of fire resistance of wood structure at the same time points out the lack of research. Based on the above background and related achievements, the academic ideas and research goals of this paper are discussed. (2) the wood properties test of laminated wood laminates, and the thermal and mechanical properties of wood at high temperature are summed up for wood structure test. And the numerical analysis calculation provides material performance data. (3) 1 single single span single span mortise and mortise joint wooden frame comparison component static load test and 3 fire frame fire limit test, considering the different holding level on its temperature field distribution, fire resistance limit and failure mode. The results show that the holding level is small, mortise and tenon joint wood frame. In the fire process, the main damage of the beam is first, and when the holding level is large, the joints of the mortise and tenon joints are mainly damaged in the process of fire. (4) the finite element model of second fire frames is established by the finite element software ABAQUS, and the temperature field and the structure field are calculated, and the calculation results are compared with the experimental results, and the differences are studied. The effect of load on the fire resistance on the beam shows that the results of the finite element calculation are in good agreement with the test results. And when the load is large, the finite element method can not simulate the carbonization of the upper part of the tenon because of the gap enlargement by indirect coupling.
