Our 2017-2018 Bridge

Stay tuned! We will be revealing our 2018-2019 bridge soon!

Design Summary

 

  • Overtruss was used to maximize overall depth. This increases the overall efficiency and moment of inertia

  • Warren truss was selected to maximize load/weight ratio

  • Cross braces have been used to increase lateral stiffness and to prevent the trusses from buckling

  • Members are fabricated from square HSS to increase efficiency in fabrication. In addition, they are not susceptible to lateral-torsional buckling

 

Acceleration Bridge Construction

 

  • Most of the bolts are pre-welded to the structure for faster assembly

  • The bridge components were fabricated using jigs to avoid problems with tolerances

  • Similar types of connections are used throughout the entire structure for faster construction

 

Current Construction Sequence

 

  1. Four legs are placed and loading rails are built from midspan to the ends, connecting the bottom cross braces simultaneously

  2. Loading rails are connected over the river and the bridge is supported at midspan using a pier

  3. The over trusses are built off of the loading rails and cross braces simultaneously towards midspan, while connecting the upper cross braces
