OUR PROGRESS
Take a look at the work that we are completing and follow along as we progress on our steel bridge!
The team started refining the final bridge design. Initially, the team used Visual Analysis to analyze various member sizes in order to decrease deflection while also minimizing bridge weight. The team tested various rectangular tubing ranging from 0.5”x0.5”x0.065” to 1”x1”x0.12” and analyzed the bridge under conditions where the larger sections are in tension. Additionally, the team began discussing strategies and approaches in regard to the bridge connection. The team began preliminary sketches and designs for the connections.

The team has been working on the alternative designs for the competition. Specifically, the team is implementing changes to the alternative designs to decrease the amount of members and connections in order to increase constructability and build time. Additionally, the bridges’ weight, number of members, number of connections, deflection, and distribution of axial forces have been analyzed and compared among the five bridge designs in order to determine the most optimal bridge design. Using this criteria, a design matrix and decision matrix were created to determine the most optimal bridge. |
