정부[3]에서는 강관비계를 재래식 비계로 규정하고 일체형 작업발판인 시스템비계를 우선 설치하도록 제도화 하고 강관비계의 사용을 최대한 지양하고 있는 추세이다. 하지만 발전소, 플랜트 현장 등 장비의 진입이 안 되거나 본 구조물의 구조가 복잡한 곳, 그리고 지면에서 비계를 쌓아 올리지 못하는 곳에서는 강관비계를 설치하여 작업할 수 밖에 없다. 고소부위의 H-beam 구조물에 강관비계를 설치하여 작업자들이 안전하게 작업을 할 수 있도록 작업공간을 형성하기 위해서는 철골용 클램프의 성능은 매우 중요한 요소이다. 본 연구에서는 철골용 클램프의 설치 방향별 부재의 변형 및 인장하중에 대해 성능시험 및 구조해석 모델링을 통해 확인한 결과 설치 방향별 성능은 안전인증 기준인 인장하중 10,000N을 만족하는 것으로 확인 되었다. 다만 성능값은 만족하지만 부착부 누름 볼트의 변형발생이 확인되었고, 부착부 본체는 변형이 미미한 것으로 확인되었으므로 철골용 클램프는 하중이 전달되는 방향으로 설치하여 부착부 본체에 하중이 제대로 전달될 수 있도록 하는 것이 보다 안전한 방법이다.

This study aims to identify more reasonable and efficient development plans to engage local university students in landscape improvement projects in rural areas. To survey university students, residents, administrators and experts involved in such projects on important considerations in this regard, SWOT analysis was employed to identify important factors, followed by analytic hierarchy process (AHP) to evaluate their relative importance, identify problems and suggest implications for improvement. The results are summarized as follows: the relative importance of the SWOT group was in the order of opportunity, strength, threat, and weakness. For each SWOT factor, the relative importance of strengths was in the order of students' aspiration and passion, availability of creative ideas and designs, and improved attachment to their community. The relative importance of weaknesses was in the order of the lack of spontaneous participation of residents, short preparation periods and insufficient budgets, and the lack of experience in similar projects. The relative importance of opportunities was in the order of young students' activity itself being a boost factor to the community, students' endeavors arising a consensus among residents, and students feeling a sense of duty as representatives of their school. The relative importance of threats was in the order of projects being one-shot, temporary events, immaturity, and differences in preferences between older and younger generations. To draw an overall ranking of the sub-factors evaluated, the overall relative importance of the decision-making factors was evaluated. Among the sub-factors for each SWOT group, young students' activity itself being a boost factor to the community as an opportunity factor was shown to be the most important, while the lack of experience in similar projects was shown to be the least important as administrators and experts made appropriate interventions in each stage.
