This paper presents a study on the stress comparison analysis of steel arch structure and gable frame structure in Jeju Island. In this paper, the study is limited to steel arch structure and gable frame structure with hinge support, steel yield strength of SHN275 and wind load of Jeju Island. The Steel arch structure and gable frame structure with the rise-span ratio as variables were analyzed. An analysis of the steel arch structure and gable frame structure was carried out by MIDAS Gen/w program. The conclusions obtained from this study on the stress comparison analysis of steel arch structure and gable frame structure in Jeju Island are as follows. First, The higher rise-span ratio of the steel arch structure was the lower the combined strength ratio, The combined strength ratio of gable frame structure was irregular regardless of rise-span ratio. Second, The combined strength ratio of the steel gable frame structure was 8~15% higher than the combined strength ratio of the steel arch structure when the rise-span ratio was 0.2 or higher. Third, It was found that the steel arch structure is the more efficient to minimize the size of beams and columns than gable frame structure.
