High-precision 3D reconstruction technology demonstrates unique advantages in seismic performance analysis of ancient architectural mortise-and-tenon structures. Through digital acquisition and detailed modeling, it enables comprehensive restoration of geometric details and connection methods at mortise-and-tenon joints, providing highly reliable data support for subsequent mechanical simulations. Under earthquake conditions, the force modes and energy dissipation mechanisms of mortise-and-tenon structures can be quantitatively analyzed through virtual simulations, thereby revealing their seismic characteristics and failure paths. This method not only overcomes the limitations of traditional experiments in terms of scale and repeatability but also facilitates multidimensional parameter studies for complex structures. Research findings indicate that combining 3D reconstruction with finite element analysis can more accurately evaluate nonlinear responses at mortise-and-tenon joints, enhancing the scientific rigor of ancient building conservation and reinforcement design.
