For those who want to learn something, I have been following this guy's Youtube channel. He is a structural engineer in Florida so more than qualified to comment on the types of things that could have caused the collapse. He quickly ruled out "climate change". This building had massive water intrusion problems. Not just rain water but sea water. There are probably going to be some design/construction defects found but the main culprit will be severe lack of maintenance. Improper repairs in the past may of played a part as well. Spalling of the concrete pillars is what would bring a building down like that. Water intrusion causes the rebar to expand and blows out the concrete. Once the rebar is exposed the damage increases exponentially. As the rebar rusts and loses structural integrity, the columns will buckle. Concrete is strongest in compression and steel rebar in tension. It takes both to keep the structure standing. https://www.youtube.com/c/BuildingIntegrity/videos 1 Quote Link to comment Share on other sites More sharing options...

You'd need quite a plan to build that high, on sub par soil, that close to the water table, with salt air. Seen up here, no salt water, but 3 story monster homes on what was all fresh fill. Engineers demanded massive excavation, pump in hundreds of yards of 10 mpa concrete or at least unshrinkable fill. Then a mud mat of 15 mpa. Then a full slab, not just footings. then footings, rebarred to the max, with rebarred walls. Added a hundred grand to a house, albeit a few million dollar house on a golf course. Most expensive shit I saw done was for hydro towers. It was looney. 10 foot drill, going down a hundred or so feet, X4 for the base. Massive crane X2, one to lift the 10 foot steel pipe form as the concrete got poured in, one to hold the vibrator/hammer, powered with a sea can sized hydraulic power pack to get the form in and out so it lifted easier. Vacuum trucks to suck out the water as it got poured. It ain't moving, ever. I've seen galvanized rebar, and rusty rebar rejected, there are admixes in concrete that can compensate for many things when the engineer demanded it...but they can be expensive when looking at tens of thousands of yards of concrete. Like $50 a yard...that adds up. Seems cheap now that 150 people may be dead. It can an be done, for a price....I think maybe these are not quite built to that standard. You work for Hydro, Voodoo and have concrete pouring experience? I worked at DNGS for 36 yrs and spent the first 6 years pouring concrete while it was being constructed. 3 hours ago, Skidooski said: Some are blaming Global warming / Climate shift / Climate change for the building collapse Everything gets blamed on global warming nowadays and their sheep gobble it right up.
