中文摘要:
      选取徽州古民居木构架的典型榫卯节点,确定模型参数,进行数值模拟分析。分别模拟节点处没有施加“关键”和雀替、节点处只施加“关键”、节点处只施加雀替、节点处“关键”与雀替同时施加四种情况下榫卯节点处的受力情况,综合对比“关键”和雀替对木构架榫卯节点的受力特征,总结了“关键”和雀替对木构架节点受力带来的有利影响。研究表明:施加“关键”和雀替后,使构件的变形减小,受力得到改善,提高了节点的受力性能,增强了结构的整体稳定性
英文摘要:
      To determine model parameters and analyze numerical simulation by selecting the mortise-tenon joint of timber frame of ancient dwellings of Huizhou. There are four cases of mortise and tenon joint forces in this note including simulating the nodes without key and sparrow brace, applying key on the joint, applying sparrow brace on the joint, and applying key and sparrow brace both on the joint, respectively. Summarize the beneficial effect of key and sparrow brace on the timber frame node through compressively contrasting the force characteristics of key and sparrow brace for the timber frame. The result shows that, after applying key and sparrow brace, the deformation of component has been decreased and stress has been improved, meanwhile mechanical performance of node has been improved and overall stability of the structure has also enhanced at the same time
