LOCAL LOADING ON CURVED REINFORCED CONCRETE SLABS

THIS REPORT DESCRIBED A STUDY IN WHICH THE EFFECT OF LOCAL LOADING ON CURVED CONCRETE BRIDGE SLABS WAS EXAMINED AND COMPARED WITH THE PRESENT AMERICAN ASSOCIATION OF STATE HIGHWAY OFFICIAL (AASHO) CODE. A GENERAL THEORY WAS DEVELOPED WHICH INCORPORATED LARGE DEFLECTION ORTHOTROPIC PLATE THEORY IN THE ELASTIC RANGE. THE EQUATIONS AND THEIR SOLUTIONS MAY BE APPLIED TO ANY DECK CONFIGURATION. THE ORTHOTROPIC PLATE EQUATIONS ARE SOLVED BY USING THE FINITE DIFFERENCE TECHNIQUE. BOTH FLEXURAL AND IN-PLANE STRESSES ARE CONSIDERED AND THE SUPPORT CONDITIONS ALONG THE CURVED EDGES ARE VARIABLE, I.E., FREE, FIXED OR ELASTIC. THE METHOD CAN BE APPLIED TO THE ANALYSIS OF A CURVED SLAB AND GIRDER BRIDGE BY IDEALIZATION OF THE BRIDGE DECK TO AN EQUIVALENT ORTHOTROPIC PLATE. A GENERAL COMPUTER PROGRAM FOR SOLVING THE EQUATIONS HAS BEEN DEVELOPED ON AN INTERNATIONAL BUSINESS MACHINE (IBM) 7094 COMPUTER. EXPERIMENTAL WORK HAS BEEN PERFORMED ON A CURVED PLATE MODEL FOR DIFFERENT PLATE CONFIGURATIONS. COMPARISONS BETWEEN THE ANALYTICAL SOLUTIONS AND THE EXPERIMENTAL DATA ARE IN GOOD AGREEMENT. /FHWA/
