본 논문은 유닛 모듈러를 구성하는 주구조체인 각형강관 기둥과 냉간성형 LEB C-형강 보로 볼트 접합된 접합부의 거동을 실험적으로 평가하는 것이 연구의 목적이다. 접합부에서 기둥과 LEB C-형강 보를 접합하기 위한 브라켓의 두께변화, LEB C-형강 보와 브라켓 접합부 볼트 개수 등의 주요변수에 대한 실험을 통하여 기둥-보 접합부의 내력증대와 변형성상 및 파괴모드 변화 등을 고찰하였다. 실험결과, 접합부의 보강형상과 관계없이 또한 접합부의 파괴 없이 LEB C-형강 보의 국부좌굴강도가 지배하는 것으로 파악되었으며, 브라켓 두께 크기에 따라 내력과 강성이 조금 높게 나타남을 알 수 있었다. 또한 접합부에 사용된 볼트 수량에 관계없이 강성면에서 큰 차이를 나타내지 않았으며 LEB C-형강과 브라켓을 볼트접합으로 반강접합의 역학적 거동 가능성을 확인하였다.

Through analysing on construction cases of stupa built in A.D. 7,8th, I have researched about these : constructive methods of inner soil of stupa, spatial compositions, characteristics of structures, arrangements of inner soil and etc. And cases analysed are six ; Mireuksajiseoktap(stone pagoda of Mireuksa Temple site), Gameunsajisamcheumgseoktap(three storied stone pagoda of Gameunsa Temple site), Goseonsajisamcheungseoktap(three storied stone pagoda of Goseonsa Temple site), Wolseong nawolliocheungseoktap(five storied stone pagoda in Nawonri, Wolseong), Guksagokseoktap(three storied stone pagoda in Guksa valley), Giamgokseoktap(three storied stone pagoda in Giam valley). Additionally we researched about inner soil of Sacheonwangsaji tapji(basement of stone stupa site in Sacheonwang Temple site) to speculate on composition of Synthetically, the foundation could be divided as core space and outer space. ; the former as structural function and the latter as ornamental function. And the core area could be divided again as center column space and buffer space. The relationship between core spaces and its formation are as belows; First, according to the area of foundation and scale of stone pagoda, formations of core are differed. As the scale of stone pagoda goes bigger, and the area of foundation goes larger, the structure of stone pagoda comprised by center column type and layered-core which endure upper load independently. On the contrary, as the scale of stone pagoda goes smaller, and the area of foundation goes lesser, the structure of stone pagoda tend to use only center column to endure upper part. Second, spatial composition of core area is comprised as two spaces, one which endure upper load and buffer space which absorb side pressure and upper pressure. The buffer space tend to be used in case of those structures which could not endure side pressure or have lots of joint. In some cases, it was located below the cover stone of foundation and gained upper load. And in case that have not gained pressure from side stone, the buffer space are comprised by smalle stone or roof tile to get structural supplement.
