Minneapolis' New Bridge
Let's actually do some engineering here on this blog...this is a Popular Mechanics article about the reconstruction of the I-35 bridge that collapsed last year, and really showed off the crumbling nature of our infrastructure...but, this new bridge is state-of-the-art. The mode of failure in the bridge was a design where the gussets used to transfer load within the truss structure were designed, or ended up, being only 1/2 the thickness they should have been. I hedge it in this way only as the NTSB was not able to find the original calcs, so while in the end its the engineer's fault, we dont know where in the design process this happened - the calcs, the procurement, or where...speaking of new beauties, check this out...oh, and here's the latest ASCE report card...Labels: ASCE, bridge, engineering, USA
