RESEARCH ON HIGHWAY-BRIDGE FLOORS

THIS PAPER REVIEWS THE RESEARCH ON HIGHWAY BRIDGE FLOORS CARRIED OUT AT THE UNIVERSITY OF ILLINOIS DURING THE PERIOD FROM 1936 TO 1954 UNDER THE SPONSORSHIP OF THE ILLINOIS DIVISION OF HIGHWAYS AND THE BUREAU OF PUBLIC ROADS. THE OBJECT OF THIS RESEARCH HAS BEEN TO DETERMINE THE BEHAVIOR OF REINFORCED-CONCRETE SLABS SUBJECTED TO VEHICLE WHEEL LOADS AND TO INVESTIGATE THE EFFECT OF THE MANY VARIABLES ENCOUNTERED IN DIFFERENT TYPES OF BRIDGE-FLOOR CONSTRUCTION. THE METHODS USED HAVE INCLUDED A COMBINATION OF MATHEMATICAL ANALYSES AS WELL AS EXTENSIVE TESTS ON SCALE-MODEL BRIDGES AND ON FULL-SIZE ELEMENTS OF BRIDGES. TWO TYPES OF BRIDGES HAVE BEEN STUDIED: THE SIMPLE-SPAN SOLID-SLAB BRIDGE WITH INTEGRAL CURBS AND THE I-BEAM BRIDGE. TESTS HAVE BEEN MADE ON BOTH RIGHT AND SKEW BRIDGES OF BOTH TYPES, AND ON BOTH SIMPLE-SPAN AND CONTINUOUS I-BEAM BRIDGES. EXTENSIVE ANALYTICAL AND EXPERIMENTAL STUDIES OF COMPOSITE ACTION IN I-BEAM BRIDGES HAVE ALSO BEEN MADE. IN ADDITION TO THESE STUDIES OF ACTUAL BRIDGE TYPES, THERE HAVE BEEN SEVERAL ANALYTICAL AND EXPERIMENTAL INVESTIGATIONS OF FUNDAMENTAL PROBLEMS INVOLVED IN THE BEHAVIOR OF SLABS SUBJECTED TO CONCENTRATED LOADS. /AUTHOR/
