DESIGN OF RAILWAY TRACKS ON CONCRETE SLABS

EL CALCULO DE LOS CARRILES SOBRE LOSA DE HORMIGON

THIS ARTICLE DESCRIBES A DESIGN METHOD FOR RAILWAY TRACKS LAID ON A CONTINUOUS SLAB. THE METHOD USES THE ZIMMERMANN FORMULAE AND TAKES INTO ACCOUNT THE FORCES APPLIED BY THE ELASTIC FASTENINGS WHICH CONNECT THE TRACK TO THE SLAB. DETAILS ARE GIVEN OF THE DESIGN METHOD PROPOSED BY THE AUTHORS, WHICH TAKES THE FORM OF A COMPUTER PROGRAM. IT GIVES A VERY ACCURATE REPRODUCTION OF THE STRESSES AND DEFORMATIONS OF THE TRACK (USING THE WINKLER HYPOTHESES) AND SHOWS THE ADDITIONAL STRESS IMPOSED TO THE FASTENING BY THE VERTICAL WHEEL LOADS WHEN THE TRAIN STARTS TO MOVE.
