To protect Chinese ancient building,by theoretical calculation and finite element simulation sinkage as well as strengthening method on tenon-mortise joint of a face beam in Tai-He Palace in the Forbidden City were studied.2 strengthening methods were considered,by which calculation diagrams as well as finite element models for the beam were built and static analysis were carried out.Based on analysis results,displacement as well as stress distributions of the face beam before strengthened were obtained;Based on laws of cultural relics protection,the 2 strengthening methods were discussed and the more suitable one was selected.Results show that the main cause of sinkage of the face beam tenon relates closely to over great values of bending,tension as well as shearing stress values at the tenon-mortise joint position;The method that strengthening tenon-mortise joint by additional columns under the face beam may bring adverse effects to the substructure,however the method of using steel-wood composite system to strengthen the joint is more suitable which meets the demand of cultural relics protection.
