The railroad track is very important as a means of crossing the train itself, especially for lines that have a fairly extreme elevation, where for the railroad itself it is not allowed to have a track with a very high grid.
This study uses the finite element method with assistance from LISA V.8 FEA(License), a finite element method software package, to examine the stresses that develop on railroad track girder bridges in comparison to the stresses that develop on each component, including rails, sleepers, and the bridge girder itself, as a result of rail traffic loads and brake impact loads between the railroad tracks and the railroad wheels.
According to the results of the analysis of the stress distribution behavior that happens on the railroad track girder bridge with two types of loading, namely the service load and the shock/brake load, the starting stress that occurs due to the service load is 32.91 N/mm2 and the increase in stress that occurs due to the brake load is 58.85 N/mm2. The service load causes a stress distribution on the bridge girder of 9.39 N/mm2, and the brake load causes a stress distribution of 16.76 N/mm2. Whereas the ratio of the increase in stress on the railroad is 1.788, and the ratio of the increase in stress on the bridge girder is 1.784.
