표준열차하중에 대한 결정론적 접근

초록

At present, design loads of railway are divided into common railway and high speed railway separately. LS-22 which is based on American railway standards represnets common railway and HL25 which is based on Eurocode represents high speed railway. Although, the design load is the starting point for design of railway, any research for developing design load does not exsit at all. However, Europe and Japan develops the deisn load consistently with advanced design standards. Recently in Europe, deterministic, probabilistic and cost approaches are investigated for developing new design load which is called LM2000. In the present paper, as a step for developing new design load for Korean railway, deterministic processes will be introduced. Trains which are serviced now and future will be analyzed and a necessity for new design load will be presented quantitatively.
