Abstract

This paper presents a simplified analysis method using the elastic equivalent modelling not using the global finite element modelling of deck for the basic design GFRP composites deck with cellular tubes or sandwich structural type. In order to verify the validation of the simplified method ANSYS software package is used and compared the results analyzed on the global finite element modelling and the elastic equivalent modelling. And the laboratory testing by 4-point bending is conducted to compare the results based on the simplified analysis method proposed in this paper. The comparison of the results based on the analysis and the testing are discussed. It is found that the presented simplified analysis is applicable to the use in the basic design GFRP composite deck.

본 논문은 중공튜브 및 샌드위구조 형식을 주로 갖는 GFRP 복합소재 바닥판의 기본설계에서 전체 유한요소 모델링을 이용하지 않고 탄성등가 모델링을 이용한 간편 해석 방법을 제시하였다. 제시된 간편 해석 방법의 타당성 검증을 위해서 ANSYS 프로그램이 사용되었으며, 전체 유한요소 모델링과 탄성등가모델링을 이용한 해석값을 각각 비교하였다. 또한 본 논문에서 제안된 GFRP 복합소재 바닥판 간편 해석법에 의한 해석 결과를 비교하기 위해 각형 튜브를 갖는 샌드위치 구조형식 GFRP 복합소재 바닥판의 4점 휨시험인 실내실험결과를 수행하였다. 해석 결과와 실험 결과 내용을 비교분석하였다. 제시된 간편해석 방법은 GFRP 복합소재 바닥판의 기본설계시 사용하기에 적용성이 있음을 확인되었다.
