Abstract

The study of thermal effect on the structure is carried out in the case of Guss asphalt which is paved at the temperature of $240^{\circ}C$ or higher in the bridge pavement of the steel deck bridges. However, studies on the heat source data applicable to numerical analysis are insufficient, the temperature load is used as a joint load. In this study, the heat source equations that can be directly loaded on the plate elements, although limited, are presented using the measured temperature data in the Guss asphalt pavement and its validity is confirmed by a brief numerical analysis.

강바닥판 교량의 교면 포장에 $240^{\circ}C$ 이상의 온도에서 포설 되는 구스 아스팔트 가 적용되는 경우, 구조물에 발생하는 열 영향의 검토를 수행하지만, 수치해석에 적용 가능한 열원 데이터에 대한 연구는 미흡하여 단순화된 온도 하중을 절점 하중으로 사용하고 있다. 이에 본 연구에서는 구스 아스팔트 포장 시 계측된 온도 데이터를 이용하여 비록 제한적이지만 평판요소에 직접 재하 가능한 열원 방정식을 구성하여 제시하였으며 간략한 수치해석을 통해 그 타당성을 확인하였다.
