PERMISSIBLE MAXIMUM VALUES FOR THE Y AND Q FORCES AS WELL AS THE RATIO Y/Q. LIMIT VALUES FOR THE Y AND Q FORCES FROM THE POINT OF VIEW OF RAIL STRESSES

First a survey is given of the previous studies and of the possible criteria to be retained. The calculation methods used for determining the stresses in the rail are then described. The first results are presented graphically by giving, as a function of the Y and Q loads, the maximum tensile and shear stresses occurring in a UIC 60 rail for a load applied between two sleepers.
