| Abstract |
This paper focused on the evaluation of static safety according to stereo form in the stone pagoda which is one of the main cultural heritages in Korea. Frist, the damage types and present reinforce conditions of stereobate in the stone pagoda were surveyed. And then Sun-san Jukjang-dong 5-story stone pagoda was selected as a sample model for constructing analytical model of stone pagoda since its measured drawing had been made. The stress distribution and reactions of the upper-capstone(Sangdaigopsuk) in the stereobate were obtained by using finite element model analysis, and it was identified that core-stone plays a role of distributing the stress of the upper-capstone and about 1mm of settlement prevents the inner stuffing to support the upper-capstone. Also, 3-D modelling of the entire stone pagoda was conducted by 3DEC program using a discrete element model, and the stress distribution and displacement of all the members were obtained. The analyses results indicated that the existence of the core-stone and the condition of core-stone arrangement reduced the value of the maximum stress and displacement by transferring the self-weight mainly to the core-stone. |
