Which is the Strongest Steel Bridge Design? Hydraulic Press Test!


Which is the strongest steel bridge design? We had design competition where our viewers designed their own steel bridge designs that we laser cut out from structural steel sheet and then tested with 40 ton press and 150 ton force sensor.

Bridge building rules!

The .stl file is maximum size/dimensions for bridge's sides/supports structures. There is going to be two of those and 30mm wide road surface between those two. Side supports are going to be probably 2 mm thick and road surface 4 mm. I might change those if necessary to get reasonable results.

Modify the .stl file in a way that you keep the holes that are used to connect the road surface to support structures in their original place. Also don't change the distance between surfaces that touch the support sturcture that is holding the bridge on it's place. Check the .pdf file to see where those are located.

There isn't any maximum weight or surface area for side structures but the result of each bridge is going to be divided by mass of the bridge to get the points of design. So light and strong is the way to go! Bridges are going to be weight with road surface installed.

When you have finished your design save your design as an .stl file and send it to hpcsuomi@gmail.com If you have some spesific theory behind your design you can include that into email.

Winner is going to win again some HPC merch from our merch store.

Do not try this at home!! or at any where else!!
