Two weeks ago, Lehigh University participated in ASCE’s Mid-Atlantic Region Student Conference hosted by Drexel University. One of the competitions Lehigh participated in was the Steel Bridge Competition. Since it was my first time going to the event, I was really excited to see what the competition was all about. (Throughout this semester, I helped in the construction of the bridge by cutting some of the angle-pieces, etc. and I was really excited to see where all my work was being used!) The build-team, which consisted of 5 students from Lehigh, ended up building the bridge in under 45 minutes, from which I understand is a big improvement from last year’s time.
Although the bridge passed the lateral test, it did not pass the vertical loading test. Our bridge deformed to an extent where the arches appeared to buckle under the weight added to it.
As I watched the bridge deform under the load, all that came to mind was Mech003, which I took instead of CEE3: Engineering Statics, and the stuff we learned about bridges, distributed loads, stress concentrations, plastic deformations, bending, etc. It was really cool seeing what I had learned in a class setting I was seeing in real life and how the concepts and equations applied to real structures. As finals begin next week for all Lehigh students, the deformation of our bridge will definitely help me remember some of the equations used in Mech3 as I now have visual aids to help me remember!
