As a fellow SE in Oregon, I’m glad you post these. Let’s keep the profession alive and strong. We need more technically proficient structural engineers in the industry. Your content brings important awareness to the profession. 👍
Can you make a video on the exact topics that are really useful to a civil engineer in Algebra, Trigonometry, Geometry and Vector Statics. Thanks
Glad you’re back!
I’m pursing Structural Engineering in Texas and your channel has helped me!
Glad you are back.
Hello, Mat. Could you talk about concrete spalling phenomena?
What about a composite over wrap vs a steel jacket?
Hi Mat ! Can you make a video about daily vlog please ? What do you do at your office or working place ? About your construction place if any. Thank you! I am studying civil engineering.
Driving by the location, it looks like they retrofitted the columns with jackets similar to the other freeway earthquake retrofits.
but now the rebar has been changed by the extreme heat and will start degrading from the humidity though right?
Great video, valuable information. I have a doudt, usually the hottest part of a flame is in the top or the tip, so I would expect the damage should greater in the upper side of the structure like in the slab or beams in stead of the columns or piers. Why it appears most the damage is in the columns? Is maybe the damage not due to the fire itself, but from the water jet from the firefighting?
Obiously the water jet would be the smaller evil to stop the fire, no blaming there. I just don't know the fire damaging process in reinforced concrete.
The deck is also a heatsink with the top not exposed to the fire, that could have been helpful. Also the cover at the bottom may be thicker because of fire hazard. The damage on the column could be in the halfway location because of the higher buckling stresses there, causing the cover to shear off. I doubt the water could blast off the cover.
Great video Mat! I always enjoy trying to figure out why a structure failed, it’s good learning material for a structural engineer.
Base on the information you presented, your judgment was well noted and I second you statement.
