초록
이 연구에서는 복공판 지간에 관계없이 일률적으로 적용되고 있는 하중부담계수의 타당성 및 적용성을 지간길이 2 m, 3 m 및 4 m의 복공판에 대한 전체계 복공판 모델에 대한 구조해석을 통해 검토하고자 한다. 또한, 복공판 지간길이에 따른 보정계수 적용을 통해 이론적 계산 방법에 대한 오차를 감소시켜 보다 정확한 평가를 위한 방안을 제시하고자 한다. 이들 연구로부터 하중부담계수를 로그함수를 사용한 추정식으로 나타내었으며, 이들 식을 적용하여 무늬 H형강 1개에 대한 이론적 계산에 의한 산출된 응력 및 처짐을 보정하면, 복공판 전체계 구조거동과 유사한 거동을 나타내는 것을 확인할 수 있었다.
Abstract
In this study, the validity and applicability of the load burden factor, which has been uniformly applied regardless of the deck plate span, will be examined through structural analysis of a full-system deck plate model with span lengths of 2 m, 3 m, and 4 m. Additionally, by applying correction factors based on the span length of the deck plate, we aim to reduce errors in theoretical calculation methods and propose a more accurate evaluation approach. From this research, the load burden factor was represented as an estimation equation using a logarithmic function. By applying this equation to correct the stress and deflection calculated theoretically for a single checkered H-beam, it was confirmed that the behavior closely resembles the structural behavior of the full-system deck plate.
