Abstract
The damages of Preah Pithu temple in Cambodia have been increased due to weathering and corrosion for a long time. In particular, the U temple was seriously damaged and required the evaluation of structural safety for the preservation of temple. Because the stones of the Preah Pithu U temple are individually stacked, it is necessary to introduce the modeling and analysis technique for the discontinuous contact surfaces of masonry structures. For this purpose, we examined the construction and damage status of Preah Pithu U temple. Then, we analyzed the structural behavior and evaluated the structural safety of Preah Pithu U temple using the discrete element method. The vulnerable parts were revealed at the sides of the north and west walls from the results. In addition, the assessment for compression or tensile failure for each member was performed. Also, it is necessary to be carefully checked because some slipping occured in the lower parts of the wall.
