SIMPLIFIED DESIGN LIVE LOAD PATTERNS FOR USE IN CONTROLLING VEHICLE WEIGHTS ON BRIDGES

THIS IS ONE OF FOUR REPORTS ON AN INVESTIGATION INTO THE EFFECTS OF VEHICLE LOADS ON HIGHWAY PAVEMENT AND BRIDGE STRUCTURES, AND DEALS PARTICULARLY WITH CONTINUOUS BRIDGES. THE MOMENTS AND SHEAR FORCES GENERATED IN CRITICAL POINTS OF CONTINUOUS STRUCTURES BY ANY GROUP OF AXLE WEIGHTS, CAN BE SIMULATED BY TRANSFORMING THE AXLE GROUP INTO A SIMPLIFIED LOAD PATTERN CONSISTING OF A UNIFORMLY DISTRIBUTED LOAD TOGETHER WITH A CONCENTRATED LOAD. THE METHOD OF TRANSPORTATION IS OUTLINED. OBSERVATIONS MADE DURING A TRUCK SURVEY WERE USED TO COMPILE A SERIES OF COMMONLY OCCURRING AXLE SEQUENCES, LOADED TO THEIR MAXIMUM OBSERVED WEIGHTS AND HAVING THE SHORTEST INTERAXLE DISTANCES. THESE CRITICAL AXLE GROUPS WERE TRANSFORMED INTO THEIR EQUIVALENT UNIFORMLY DISTRIBUTED AND CONCENTRATED LOADS, AND THIS DATA CAN BE USED TO PROVIDE REALISTIC SIMPLIFIED LOAD PATTERNS USEFUL IN DESIGN. /TRRL/A/
