What is the Vehicle Load Classification?
1 Answers
Vehicle load classification is represented by vehicle fleets, which are divided into four levels: Vehicle-10, Vehicle-15, Vehicle-20, and Vehicle-Super 20. Below is relevant extended information: 1. Basic Introduction: The numerical value of the load classification indicates the total weight in tons of a main vehicle. In each fleet level, there is only one heavy vehicle, with main vehicles positioned before and after it. A heavy vehicle refers to the vehicle with the largest total weight within a specified load classification. Through the analysis, synthesis, and summarization of actual vehicle factors such as the number of axles, the distance between front and rear axles, and axle pressure, standardized loads for bridge design are stipulated in the highway bridge and culvert design specifications. 2. Application: During bridge design, lane loads should be arranged according to the number of design lanes determined by the standards. Each design lane must be equipped with a lane load. Longitudinally, the standard value of uniformly distributed load can be arbitrarily intercepted along the bridge's longitudinal direction and fully distributed on the influence line of the same sign that causes the most unfavorable load effect on the structure. The standard value of concentrated load PK acts at the peak of a corresponding influence line. Transversely, both uniformly distributed loads and concentrated loads are evenly distributed within the 3500000mm width of the design lane.
