DYNAMIC STUDIES OF TWO CONTINUOUS PLATE-GIRDER BRIDGES
PARTIAL RESULTS ARE PRESENTED AND DESCRIBED OF TESTS CONDUCTED BY THE BUREAU OF PUBLIC ROADS AND THE OREGON STATE HIGHWAY DEPARTMENT ON TWO THREE-SPAN, CONTINUOUS PLATE-GIRDER BRIDGES IN OREGON. MEASUREMENTS INCLUDE DEFLECTION OF THE GIRDERS AND STRAIN IN THE GIRDERS, STRINGERS, AND FLOOR BEAMS UNDER TEST VEHICLES APPROXIMATING THE AASHO H20-S16-44 TRUCK AT SPEEDS OF 5 MPH. TO 45 MPH. TEST DATA ARE PRESENTED IN CURVES SHOWING VARIATION OF STRESS AND DEFLECTION WITH SPEED. COMPARISONS ARE MADE WITH STRESSES AND DEFLECTIONS CALCULATED ACCORDING TO EXISTING SPECIFICATIONS. MEASURED STRESSES IN GENERAL ARE FOUND TO BE LOWER THAN CALCULATED VALUES. BY COMPARISON OF THE RESULTS FROM THE TWO BRIDGES, DECK SURFACE CONDITION IS CONSIDERED TO BE AN IMPORTANT FACTOR IN THE VIBRATION OF ONE OF THE BRIDGES. /AUTHOR/
