STRESS ANALYSIS OF CONCRETE TRACK SLABS ON AN ELASTIC FOUNDATION BY THE FINITE ELEMENT METHOD

In analyzing the track slab stress, it has been revealed that the beam theory has led to certain discrepancies and left unexplicable parts of the actual phenomena. But it is found that these drawbacks can be eliminated by assuming that the rail supporting elasticity is concentrated at fastening devices and considering the track slab as a plate, with the aid of a mechanical model analysis. For the analysis of the plate the finite element method is employed for its flexibility in applying the boundary conditions. The slab track is divided into many triangular elements and analyzed by using the hybrid type potential energy principle. The theoretical results thus obtained are in good agreement with those observed and they are practically employed in the slab track designing.
