• Abstract:
  The main objective of this study is to propose a new simplified equation that is based on the AASHTO LRFD formula and does not require an iterative procedure. The new simplified equation is intended to be at least as conservative as the LRFD equation. Additional objectives of the study are (1) to investigate the influence of secondary elements on the lateral load distribution of typical steel girder bridges; and (2) to examine the effects of deck cracking on the load distribution mechanism through nonlinear analyses.
