Abstract
This study is mainly intended to examine gusset plate described on the basis of the load resistance factored design (LRFD) method. The determination of design based on the full plastic strength of gusset plate in accordance with the current AASHTO Specifications. The I-40 bridge gusset plates considered herein were designed in accordance with the previous allowable stress design (ASD) method. Therefore, new design methodology will be applied to this gusset plate bridge in this study suggested by new LRFD method. The design strength models to evaluate resistance strength against available failure modes such as tension yielding and block shear rupture are presented. In addition, detailed equations are described with step-by-step procedures. Finally, the rating factor between resistance strength and applied loading, which indicates life safety, will be presented according to available failure modes.
