Abstract

This research investigates the effect of seismic load on Wat Mahathat Sukhothai Pagoda. The current dimensions of the main pagoda are determined based on the terrestrial 3D laser scanning data. According to the obtained data, the main pagoda's current inclination angle and deformation can be reported. The 3D point cloud data of the main pagoda is applied to develop the finite element model. The static analysis and free vibration analysis of the main pagoda are evaluated at first. At least three different ground motions, which are compatible with DPT1302, are applied to the finite element model for seismic response investigation. The distribution of stresses and deformation, according to the seismic load, are also presented and discussed.
