MODEL STUDY OF A 60 DEGREE THREE SPAN SKEWED BRIDGE

A REPORT OF AN INVESTIGATION CONDUCTED IN THE DEPARTMENT OF CIVIL ENGINEERING, UNIVERSITY OF TORONTO IN CO-OPERATION WITH THE ONTARIO DEPARTMENT OF HIGHWAYS AS PART OF THE ONTARIO JOINT HIGHWAY RESEARCH PROGRAMME. THE INVESTIGATION HAS BEEN SET UP TO STUDY THE BEHAVIOUR OF A 60 DEGREE THREE SPAN SKEWED BRIDGE WITH EDGE STIFFENING BEAMS. IN ADDITION TO LOAD TESTING THE PROTOTYPE, TWO MODELS, ONE OF ALUMINIUM, THE OTHER OF REINFORCED CONCRETE WERE CONSTRUCTED AND TESTED IN THE LABORATORY. DEFLECTIONS, CONCRETE STRAINS, AND STEEL STRAINS WERE RECORDED AT VARIOUS LOAD LEVELS DURING THE TESTS AND FROM THESE DATA MOMENTS AND SHEARS HAVE BEEN COMPUTED FOR BOTH MODELS. A COMPARISON OF MODEL RESULTS WITH EACH OTHER AND WITH THE OBSERVED PROTOTYPE BEHAVIOUR HAS BEEN MADE AND INCONSISTENCIES, ARISING FROM THE USE OF ALUMINIUM TO REPRESENT CONCRETE, ARE DISCUSSED. IT IS ANTICIPATED THAT THESE TEST RESULTS WILL PROVIDE SOME EXPERIMENTAL CONFIRMATION FOR A GENERAL SKEWED SLAB THEORY CURRENTLY UNDER DEVELOPMENT AT THE UNIVERSITY OF TORONTO. /CGRA/
