摘要：
Representative Dou Gong (Corbel Brackets) joints in the Guanyin Pavilion of Dule Temple were selected as the prototype joints. Three Dou Gong joint specimens at scale of 1/3.2 were fabricated conforming to the Fabrication Methods of Song Dynasty's third-class material construction. Through vertical load tests, the key performances such as load-displacement curve, failure characteristics, vertical compressive stiffness, and vertical load path, were studied. The results show that: the specimens mainly fail in Lu Dou's buckling and cracking, Mud Gong's fracture and buckling, and the fork column's bending and warping. The vertical load-displacement curve can be simplified by trilinear curves. During the whole deformation process, the vertical load is mainly carried out in three ways, including the fork column, the fork column and Gong, and the Gong after fork column buckling. A 3D finite element model was generated in ABAQUS to analysis the mechanical properties of the joints under vertical load. A good consistency between the test results and simulation is shown. Based on the above analysis, a load-deformation relationship model was established. The research results can provide reference for protection of existing ancient timber structure buildings with fork-column Dou Gong joints. © 2018, Editorial Office of Journal of Building Structures.
