Yingxian Wood Pagoda, the oldest and highest standing ancient of wood structure in China, was built without any metal connectors like nail, screw, or bolt. Instead, Dou-Gong brackets and Tenon-Mortise joints were used to connect all posts and beams. The Dou-Gong brackets and Tenon-Mortise joints have been playing a vital role for the pagoda to resist severe winds, earthquakes and some human-induced disasters for nearly a thousand years. To evaluate the safety of the pagoda, it is, therefore, useful to investigate the structural performance of Dou-Gong brackets. In this paper, a three-dimensional refined finite element model of typical Dou-Gong brackets of Pagoda, with detailed element mesh, complicated material constitutive relationship, and the friction formulation between the components, was developed based on ABAQUS. Finite element modeling of the structural performance of Dou-Gong under vertical was conducted.
