Sketch of Bridge Design
Bridge in Action
Data Table of Forces
Initially I had a standard cross section in block formation that seemed to work very well but was very costly. The new design I came up with uses triangles as apposed to cross sections. By varying the angles I was able to balance the bridge is safe for the truck to drive over. This design only costs $343,413 and meets all of the requirements of building a safe bridge. I believe my bridge design could use work as there is still one beam that has a stress level over .95. From tinkering around with the bridge design technology I learned that it is very important to look at how much weight is put on the joints by hanging beam supports from them.
