22mm까지의 두께를 갖는 HR Plate의 사용량을 증대시키기 위해서는 HR Plate가 강교량의 주부재를 포함한 모든 부재에 적용되는 것이 요망되어진다. 본 연구에서는 HR Plate의 적용가능 폭을 갖는 경량전철 협폭 박스거더의 가능성을 검토하였다. 빔요소와 플레이트 요소를 적용한 15개 경량전철 교량 모델들에 대해 풀모델링과 서부모델링을 적용하여 전산 구조해석을 수행하였다. 해석결과 HR Plates의 협폭박스거더는 경량전철에 적용될 수 있다는 것을 확인하였다.

The HR Plates made hot rolled coils is lower than general structural steel plates in price. No difference between general steel plates and HR Plates with thickness up to 22mm are found in most characters such as cutting operation, fabrication and even welding. It can be concluded that HR Plates with thickness up to 22mm can be applied to flanges and webs of any girders as well as longitudinal ribs, longitudinal and vertical stiffeners of steel bridges appropriately. To increase the demand of HR Plates with thickness up to 22mm, it is necessary that HR Plates is applicable to full member in steel bridge including main girder.In this study, availabilities of the narrow steel box girder of light railway transit with HR Plate width as a main member are discussed. For application of HR Plate to steel bridge with 50m span or more, new support systems in three types are presented. Computational analysis is performed in 15 bridge models of light railway transit with beam element and plate element. As a analysis results, three models in light railway transit are presented. We finally come to the conclusion that HR Plates can be apply to narrow steel box girder in the light railway transit.
