초록

본 연구에서는 국내에 새롭게 도입하고자 하는 인터모달 자동화물운송 시스템을 구현하기 위한 터미널 플랫폼 시설의 온도하중에 따른 적정 신축이음 간격을 살펴보았다. 터미널 플랫폼의 적정 신축이음 간격 검토는 미국 F.C.C.(federal construction council)에서 제안한 식을 이용하여 지역별 온도변화에 따른 최대 신축이음 간격을 설정하고, 구조해석 프로그램을 통해서 산출된 최대 변위값과 건축구조 수평변위 제한값을 비교하였다. 적정 신축이음 간격은 온도변화로 인한 구조물 최대 변위량이 수평변위 제한값 이하가 되는 슬래브 길이로 선정하였으며, F.C.C 제안식을 통하여 산정한 지역별 최대 신축이음 간격을 적용하여 구조물 최대 발생 변위를 살펴본 결과, 건축구조 수평변위 제한값 이내에서 발생될 수 있는 최대변위 값을 확인할 수 있었다.

In this study, we examined the proper spacing between the expansion joints according to the temperature load of the inter-modal terminal platform infrastructure to implement a new inter-modal automated freight transport system, which we intend to introduce in Korea. To review the proper expansion joint spacing of the terminal platforms, we set the maximum expansion joint spacing according to the regional temperature changes using the equation proposed by the Federal Construction Council (FCC) of the United States. Then, the maximum displacement value, which was calculated through the structural analysis program, and the limit of the horizontal displacement of the building structure were compared. The proper expansion joint spacing was selected as the slab length at which the maximum displacement of the structure, due to temperature changes, was below the horizontal displacement limit. Based on the application of maximum expansion joint spacing for each region calculated through the FCC's suggestion, the maximum displacement that could occur within the limit of the lateral displacement of the structure was determined.
