Abstract

This paper presents the results of the parametric study to investigate the effects of several analysis modeling parameters such as support conditions, member connectivities and cable member stiffness on the main mode shapes and natural frequencies of a representative disaster resilient greenhouse structure. In addition, an ambient vibration test was performed on the representative greenhouse structure and its main mode shapes and natural frequencies were obtained. By comparing the experimental and analysis results, a proper analysis modeling method of the representative greenhouse structure was proposed.

본 논문에서는 온실 구조물의 구조 성능 검토 시 적합한 모델링 방법을 제시하기 위해 대상 온실 구조물을 선정하고 지점 및 접합부 조건 그리고 케이블 요소의 단면적을 변화시켜 가며 파라메트릭 스터디를 수행하였으며, 이들 파라메터의 변화에 따른 대상 구조물의 주요 모드 형상 및 고유진동수 변화를 조사하였다. 또한 대상 구조물에 대해 현장 가속도계 측정법을 이용하여 상시진동을 계측하여 주요 모드 형상 및 고유진동수를 측정하여 해석 결과와 비교하였다. 이들 비교 결과로부터 대상 온실 구조물의 해석에 적합한 모델링 기법을 제시하였다.
