COMPUTER-AIDED GRAPHICAL ANALYSIS OF BRIDGES UNDER VEHICULAR LOADING

摘要

A computer-based, graphical approach is presented to construct the Influence Profile for deter- minate bridge structures that are subjected to multiple axle loads. An Influence Profile represents the variation of an internal or external force, or moment, at a specific location of a structure, under loading by an actual vehicle (e.g., AASHTO HS-20 truck, American Railway Engineering and Maintenance-of-Way Association (AREMA) Cooper E-80 train).
