초록

복공판은 지하공사 시 굴착현장 주변에 설치하여 지상의 차량 및 보행자의 안전한 통행을 확보함과 동시에 지하공간을 확보하는 구조물이다. 그러나 복공판이 반복적인 차량 하중을 직접적으로 받게 될 경우, 구조적 손상 및 사고 위험이 커지는 문제점이 있다. 이 연구에서는 무늬 H형강으로 제작된 규격 2 m 및 3 m의 복공판 및 장지간화를 도모한 규격 4 m의 복공판에 대한 구조해석을 통해 구조거동을 분석하고 무늬 H형강 복공판의 안전성과 사용성을 검토하였다. 해석결과, 규격 2 m – 4 m의 무늬 H형강 복공판에 대한 이론적 해석(단일 무늬 H형강) 및 전체계 구조해석에 의한 응력은 모든 해석경우에 있어서 허용응력을 만족하여 충분한 구조적 안전성을 가지고 있는 것을 확인하였다.

Abstract

The deck plate is a structure installed around excavation sites during underground construction to ensure the safe passage of vehicles and pedestrians on the ground while securing underground space. However, when the deck plate is directly subjected to repetitive vehicle loads, there is an increased risk of structural damage and accidents. In this study, structural behavior was analyzed through structural analysis of deck plates made from checkered H-beams, with standard lengths of 2m and 3m, as well as a 4m-long checkered H-beam designed for longer spans. The safety and usability of the checkered H-beam deck plates were reviewed. As a result of the analysis, it was confirmed that the stress derived from theoretical analysis (single checkered H-beam) and overall system structural analysis for checkered H-beam deck plates with dimensions of 2 to 4 meters satisfied the allowable stress in all analysis cases, ensuring sufficient structural safety.
