BlankHowdy Vorts, Rather surprised that one of our structural engineers in the group has not posted a comment on the Minneapolis bridge collapse.
Truss bridge designs have an inherent weakness at the joints. Used to use rivets back then. It does require a stretch to accept the premise that a single joint failure could result in such a chain reaction free fall. I could almost buy a series of failures given a time frame but the US Corps of Engineers vid shows the whole shebang dropping together.. hmmm. I used to be sucha trusting soul ..but.. after bldg 7 world trade center collapse... well.. Richard
