Abstract

본 논문은 공간구조의 기본 요소인 피라미드형 구조단위에 대한 해석과 포스트텐션 시험의 결과를 기술하였다. 시험과정 중에 관찰된 거동 특성을 분석하고 수치해석의 결과와 비교 검토하였으며 시험모델에 대한 미케니즘(Mechanism)을 기하학적 해법으로 확인하였다. 이 논문의 결과는 다 방향성을 가진 조인트 시스템(Mero Joint System)을 이용한 공간구조의 거동을 정확하게 예측할 수 있고 비교적 작은 포스트텐션력으로 공간구조의 형성과 시공이 가능함을 제안하고 있으며 공간구조가 미케니즘을 포함할 경우 큰 변형이 일어나므로 비선형 거동을 고려해야 함을 나타내고 있다.
