You're comparing wind loads to seismic shaking, which stresses the structure differently. Phyllis explained to me that the problem with tilt-ups is lack of bracing strength - they're just not designed to be shaken back and forth for a long time. Compounding the problem is that the joints are very hard to inspect after the structure is built.
- pronoiac 11y agoHey, the author's here! Were you in the area when Iben Browning predicted a big earthquake from New Madrid, back in 1990? Did that pique your curiosity about it?
- idlewords 11y agoI don't remember it firsthand, though it must have been in the news. I was 15 at the time and living near Chicago. Everyone on the trip was cursing the guy's name. I first got curious about New Madrid sometime in the 2000's after seeing a Wikipedia link, but don't remember the circumstances.
