The stone pagoda of Mireuk temple site is currently restoring through the repairing process. This stone pagoda has the various construction types in the inner and outer space. Therefore, the stress concentration and structural behavior need to be considered through the analysis of various construction patterns. To this end, this study presents the structural modelling and analysis considering the discrete element analysis technique to solve the discontinuum behavior between the stone elements. Also, this study performs the structural performance evaluation through the various design variables for the safety of stone pagoda. Through the analysis results, we can find out the small stress concentration in the several members. But, because the stresses and displacements are relatively small, we can secure the safety of the whole structure.

This research was to suggest the types according to structural system of the pagoda in ancient East-Asia and analyze the pagoda to the west of Mireuksaji temple site by these types. It will be possible to understand consistently the relation of the various form of the pagoda. The results of this research were described separately as follows. 1. The Buddhist pagodas founded in the ancient East Asia can be categorized according to their structural system, which provide us with insight to understand the interrelationship of categories. The pagoda is mainly classified into three categories. The first consists of two structures, an internal and an external structure. The second exposes its internal structure to the outside, and the third has the external components changing into the internal ones. 2. Although the pagoda to the west of Mireuksaji Temple Site have an internal and an external structures, it actually solves the structural problem by adopting the masonry structure in the outside as well as in the inside. Especially in this structural consideration can be found in the stylobate and the foundation structure of the pillar. The plan of the pagoda to the west of Mireuksaji Temple Site was intended to reveal the plane of the post-lintel layered construction which has a member, a main pillar, and the inner space in the cube with stones.
