CANADIAN WELDED GIRDER BRIDGE PRACTICES

THIS PAPER DESCRIBES A SERIES OF 18 WELDED CONTINUOUS GIRDER HIGHWAY BRIDGES CONSTRUCTED IN THE PROVINCE OF QUEBEC, CANADA, DURING THE PAST FOURTEEN YEARS. THESE BRIDGES VARY IN LENGTH FROM 220 TO 1550 FT., CONTAIN FROM 3 TO 14 SPANS OF FROM 35 TO 180 FT., AND ARE ALL OF THE SAME BASIC PATTERN. THE ECONOMIES AND BENEFITS RESULTING FROM THE COMBINATION OF WELDING, CONTINUITY OF GIRDERS AND DECK, UNIFORM SPACING AND CANTILEVERING OF FLOORBEAMS, ETC. ARE OUTLINED. THE PAPER ALSO DISCUSSES SOME CURRENT DIFFERENCES BETWEEN AMERICAN AND CANADA BRIDGE AND WELDING SPECIFICATIONS IN REGARD TO LOADING ASSUMPTIONS, MINIMUM WEB THICKNESSES, STIFFENER DESIGN, AND WELDING REQUIREMENTS AS THEY AFFECT THE OVERALL DESIGN AND FABRICATION PROCEDURES. INCLUDED IS A REPORT ON A RECENT FAILURE IN ONE OF THESE BRIDGES, THE SUBSEQUENT EXHAUSTIVE INVESTIGATION AND RECOMMENDATIONS FOR THE PREVENTION OF SUCH FAILURES IN THE FUTURE. /AUTHOR/
