TRANSVERSE REINFORCEMENT OF CONTINUOUS, TROUGH-SHAPED CONCRETE RAILROAD STRUCTURES

TRANSVERSE REINFORCEMENT REQUIREMENTS FOR TROUGH-SHAPED, CONTINUOUS, 2-SPAN, CONCRETE RAILROAD STRUCTURES WERE STUDIED. THE EFFECTS OF THREE SPAN, CONCRETE RAILROAD STRUCTURES WERE STUDIED. THE EFFECTS OF THREE SPAN LENGTHS, THREE WEB SLOPES, TWO LIVE LOADINGS AND THREE VALUES OF POISSON'S RATIO WERE CONSIDERED. EFFECTS OF LONGITUDINAL PRESTRESSING FORCES WERE ALSO STUDIED. DEAD AND LIVE LOAD STRESSES WERE DETERMINED BY MEANS OF A COMPUTERIZED FINITE ELEMENT PROGRAM. THEORETICAL RESULTS INDICATED NEED FOR AT LEAST TWO PATTERNS OF TRANSVERSE REINFORCEMENT, A VARIATION FROM THE GENERAL PATTERN BEING REQUIRED FOR ONE-EIGHTH OF THE SPAN LENGTH ON EITHER SIDE OF THE INTERIOR SUPPORT. A THIRD PATTERN MAY BE REQUIRED BY LOCALIZED HIGH PRESTRESSING FORCE IN THE VICINITY OF THE END SUPPORTS. CHARTS ARE PRESENTED FOR CONVENIENT DETERMINATION OF TRANSVERSE REINFORCEMENT REQUIREMENTS FOR STRUCTURES WITH PARAMETRIC CONDITIONS SIMILAR TO THOSE STUDIED. A SAMPLE THEORETICAL ANALYSIS OF A STRUCTURE WITH DIFFERENT PARAMETRIC CONDITIONS IS ALSO PRESENTED. /AUTHOR/
