| 摘要： | With ever-increasing numbers and the sizes of permitted vehicles and loads crossing Iowa’s highways and bridges, it has become more and more common for oversized, overweight vehicles to travel on at least four wheel lines that are evenly or unevenly spaced. The spacing of the adjacent wheel lines of dual-lane loads induces different lateral live load distributions on bridges, which cannot be determined using the current American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) or Load Factor Design (LFD) equations, which are only applicable for vehicles with standard axle configurations. |
