Thanks for the information below from the IV Thread. Missed replying to that one:
"If you read the building codes, you will see that the wind load design paramaters increase with the building height.
The question is...is the La code as hurricane oriented as the South floridia/Miamidade code.
In tall buildings, the damage will result from wind blown debris, especially roof gravel. The research was done bu Texas Tech.."
Wind load is one thing. What about waves battering the buildings? I've seen videos of waves demolishing homes and it doesn't take much to make matchsticks of them. While water is easy to swim through it's incompressible.
