STRUCTURAL MODEL TESTING - LOAD DISTRIBUTION IN CONCRETE I-BEAM BRIDGES

TESTS ARE REPORTED OF FOUR SMALL-SCALE PLEXIGLAS MODELS OF PRESTRESSED CONCRETE HIGHWAY BRIDGES CONTINUOUS OVER TWO SPANS. THE DISTRIBUTION OF A CONCENTRATED LOAD TO THE VARIOUS MEMBERS WAS MEASURED FOR DIFFERENT WIDTH-TO-SPAN RATIOS RATIOS AND SEVERAL ARRANGEMENTS OF INTERIOR DIGPARAGMS. THE RESULTS WERE FOUND TO CONFORM CLOSELY TO THOSE PREDICTED BY ELASTIC THEORY. EXCELLENT AGREEMENT WAS FOUND BETWEEN THE BEHAVIOR OF ONE OF THE SMALL-SCALE MODELS AND THAT OF A GEOMETRICALLY SIMILAR HALF-SCALE PRESTRESSED CONCRETE BRIDGE PREVIOUSLY TESTED IN THE LABORATORY. THE EFFECT OF PLACING THE AASHO LOADING H20-S16-44 ON THE VARIOUS TEST BRIDGES, CALCULATED FROM MODEL TEST DATA, IS COMPARED WITH THE AASHO SPECIFICATIONS AND CALCULATIONS BASED ON THE GUYON-MASSONNET ELASTIC THEORY. /RRL/A/
