The 2015 International Building Code (IBC) in chapter 1807.2.1 states that when a keyway is extended below the wall base to engage passive pressure and enhance sliding stability, the lateral soil pressures on both sides of the keyway must be considered in the sliding analysis. However, this...
Thanks to one and all for the clear thoughts and opinions. My take? It seems we each and all agree why, and what needs to happen with such information. The challenge is "When, Where, & How." And of course, the reliability of any "How." Cheers, Bill -- William M. Hayden Jr., Ph.D.,...
Thanks very much Ronald for the insights and reference. Cheers, Bill -- William M. Hayden Jr., Ph.D., P.E., CMQ/OE, F.ASCE Buffalo, N.Y. "It is never too late to be what you might have been." -- George Eliot 1819 - 1880 --
I think this is a case where one needs to look at outcomes. In my mind, graduates need to know that engineers are not infallible and mistakes get made through acts of omission and commission. They must know they are part of a system and the failure of the system is its weakest link. They also...
Thanks Heidi! What needs to "Find its way into the classroom" is, IMO, the most valuable parts of the above-noted 3 books. In their chapters/cases, after presenting and discussing the tech-reason for the failures as best they can, they have a "Lessons-Learned"" section at the end of each...
My engineering education did include discussions of failures in several courses. I'm not saying there couldn't be improvement or added value from additional communication between the investigating engineers and the educators, but I think we need to give credit where credit is due by...
Right-on Mitch! Some starting resources: "To Engineer Is Human: The Role of Failure in Successful Design," by Henry Petroski. 1992 "Epic Engineering failures and The Lessons They Teach," by Stephen Ressler. 2022 "The Blessings of Disaster: The Lessons That...
As always Mitch, excellent advice. And if the engineering educators get beyond the structural details of the failures(s), they will ask Deming's "Why" 5 times. It will then take them to the actual root-cause. Cheers, Bill -- William M. Hayden Jr., Ph.D., P.E., CMQ...
Hello, Ronald, William good night and thanks for this very essential subject. I appreciated a lot :) Its is very interesting at same time concerning, it caught my attention. Specially to structural young engineers to further expand their views to the core while approximating theorical...
A starter for this conversation would be hearing from educators on how they are incorporating lessons learned from disasters and failures into their classrooms. I don't think there is any better teaching tool for focusing students on the safety-critical nature of their work than past disasters...
