Abstract: This article compares and analyzes the reasons for the varying degrees of deformation, deflection, and even cracking of the lifting wooden beam frame after the renovation of a certain academic palace through the establishment of finite element numerical simulation and deformation observation data, and proposes solutions. The results indicate that the finite element model can still accurately simulate the deformation of wooden structures without considering complex factors such as anisotropy, mortise and tenon joints, and natural foundation settlement; At the same time, it has been proven that the main reason for the deflection exceeding the limit under the wooden beam frame is the unreasonable structural design; And proposed the reinforcement method of adding camel piers and accompanying beam beams to reduce the flexural span of the beam, effectively reducing the bending deformation of the beam, and providing reference for the restoration of ancient buildings.
