Abstract

Utah State University Steel Bridge (USSB) has designed a bridge to compete at the American Institute of Steel Construction (AISC) Student Steel Bridge Competition. The design process involves the analysis of many bridge alternatives to determine the most cost-effective bridge design. USSB analyzed both an under-span and over-arch bridge design based on weight, number of members, ease of fabrication, ease of construction, and vertical deflection. USSB found the over-arch bridge design to be the recommended alternative because of the minimal deflection it experiences under load compared to an under-span bridge.

USSB completed in-depth analysis using RISA 3D to design two over-arch bridges. The final bridge design minimized deflection while increasing weight and construction time in a cost-effective manner. USSB then drafted each individual member in AutoCAD. Fabrication of the steel bridge was completed by GWI Steel and USSB. The USU Steel Bridge received 2^nd place overall at the regional competition, earning a spot at the national competition.
