Behavior of Two‐Span Continuous Bridge under Truck Axle Loading
Publication: Journal of Structural Engineering
Volume 119, Issue 4
Abstract
Reactions, moments, displacements, and rotations due to axle loading in a two‐span continuous, composite‐steel girder test bridge were analyzed and compared with those calculated by finite element, American Association of State Highway and Transportation Officials (AASHTO), and the National Cooperative Highway Research Program (NCHRP) analysis methods. The simulated truck axle loads were applied on the test bridge on one, two, and three lanes to maximize positive moment at 0.4 L and negative moment at 1.0 L. The results of the study show that finite element analysis most accurately predicted the bridge behavior under the truck axle loading. The AASHTO and NCHRP analysis methods gave inaccurate results, since the loads were applied away from the supports.
