Abstract

Recently, due to the rapid growth of the leisure industry, demand for small-scale flotation and mooring pontoon platforms has been increasing rapidly. Standard rules for the design and structural safety of such structures have become necessary. This paper provides criteria that can be referenced when designing pontoon platforms, and also introduces structural safety evaluation procedures. In this study, the structural safety and stability of a 15-meter pontoon platform were investigated through structural design and finite element analysis. For platforms of less than 10 meters in length, a simple structural calculation can be used, but for platforms over 10 meters, a detailed structural strength review must be considered to meet safety guidelines defined in existing regulations. The structural strength of the initial design was examined and its structural safety was verified. For future research, it is an evaluative system was developed that can be used to examine the various loading conditions during design.

최근, 레저활동 인구 및 산업의 비약적인 발전으로 인하여 소규모 부잔교 및 계류형 폰툰 플랫폼의 수요가 급증하고 있으며, 연안에서 주로 사용되는 구조물에 대한 설계 및 구조안전성 평가에 관련한 표준 규칙 및 상세 규칙에 대한 제정이 시급하다. 이러한 문제점들에 대한 기본적인 해결책으로 본 논문에서는 설계 시 참고할 수 있는 설계 기준을 제시하고, 설계안에 대한 구조안전성 평가 절차에 대해서도 소개한다. 본 연구논문에서는 전장 15 m 폰툰형 플랫폼의 구조설계 과정 및 유한요소해석을 통한 구조 안전성을 검토하였다. 일반적인 10 m 이하 플랫폼의 경우, 간략한 구조계산서만으로도 검토가 가능하나, 10 m 이상의 플랫폼의 경우 상세 구조강도 검토가 뒷받침되어야만 기준에서 제시하는 안전성 확보를 위한 지침에 부합할 수 있다. 유한요소해석을 통하여 설계안에 대한 구조강도 검토를 수행하였으며, 그 안전성을 확인하였다. 추후 연구로서는 다양한 하중조건을 동시에 검토할 수 있는 시스템개발이다.
