DESIGN METHODOLOGY

摘要

The original design calculations by Sverdrup & Parcel for the I-35W Bridge which were supplied by Mn/DOT did not include any information for the primary truss gusset plate designs. It was therefore impossible to check or comment on the original design calculations for the gusset plates in the main trusses. For this report, a basic design methodology was established to enable checking of the main truss gusset plates. This design methodology is consistent with the methodology used by Sverdrup & Parcel to design the gusset plates for the floor trusses in the I-35W Bridge. In addition, the gusset plate design methodology is consistent with that used in several more modern truss
