Abstract

This paper aims at developing an environmentally friendly modular dome structure system with highly filled extrusion wood-plastic composite (WPC) member, and manufacturing a real-size specimen by modularizing members and nodes. The member used in the model is the WPC member with 70% wooden fiber contests, which is higher then previous WPC one. Its members and nodes are modularized by analyzing geometric characteristics of icosahedral-based geodetic dome. Applicapability of the 6ea prototype nodes and 3ea prototype members to the modular dome is examined with the results of the modulaization and the making process for the real-size specimen. Besides, from the analysis results, the lowest buckling mode is expected to be a nodal buckling on a node near the boundary.

본 연구의 목적은 고충진 합성목재를 이용하여 친환경 모듈러 돔 구조시스템을 개발하고 부재와 절점을 모듈화하여 실제 구조체을 제작하는 것이다. 기존의 합성목재에 비해 높은 70% 목분함량 합성목재를 돔 구조모델의 부재로 이용하였고, 정이십면체 기반 지오데직 돔의 기하학적 특성을 분석하여 절점과 부재를 모듈화 하였다. 돔의 제작을 위한 모듈화와 실제 구조물의 제작과정의 연구결과로부터 6가지 절점과 3개의 부재종류의 모듈러 돔에 대한 적용성을 검토할 수 있었다. 또한 해석결과에서 최저차 좌굴모드는 경계부의 절점에서 절점좌굴이 예상되었다.
