[미발표] 표준열차하중 변경이 기존구조물에 미치는 영향

The design load is very important factor in the design that affect the cost of construction, structural safety and the life of the structure. Studies on the design load the new standard in Europe and Japan have been performed continuously. The purpose of this study proposed for new design load which is presented by cost-effectiveness analysis of resultant of the bridge structures and construction costs. For this purpose, of spans and the height of beam related to bridge superstructure types typically used in railway, numerical simulations are performed. As a result, the lack of that increase construction costs due to changed new proposed design load. The new proposal for design load is reasonable and effective standards to evaluate.
