INVESTIGATION OF HORIZONTALLY CURVED REINFORCED CONCRETE BOX BEAM

THE DESIGN OF HORIZONTALLY CURVED BRIDGE GIRDERS IS COMPLEX, AND SIMPLIFYING ASSUMPTIONS ARE MADE BY DESIGNERS TO FACILITATE ANALYSIS. THE RELIABILITY OF TWO METHODS OF ANALYSIS WAS CHECKED BY PLACING STRAIN GAGES ON LONGITUDINAL REINFORCING STEEL AND STIRRUP REINFORCING STEEL AT SEVERAL CRITICAL LOCATIONS ON A TWO-SPAN CONTINUOUS, CURVED CONCRETE BOX BEAM. IN ADDITION, LOAD CELLS WERE PLACED AT THE THREE REACTION POINTS AND AT SIX LOCATIONS WHERE THE CURVED BEAM SUPPORTS SECONDARY STRUCTURAL MEMBERS. THE TEST RESULTS WERE IN FAIRLY GOOD AGREEMENT WITH VALUES COMPUTED BY THE CURVED-BEAM METHOD OF ANALYSIS. VALUES COMPUTED BY THE STRAIGHT-BEAM METHOD OF ANALYSIS WERE NOT IN AS GOOD AGREEMENT WITH THE TEST RESULTS. /AUTHOR/
