That's true, worth noting. Once you get past 150mph gusts, even stronger buildings have trouble. The eyewall of a storm like this (or andrew) is often as powerful as a significant tornado.
Of course it has been a few years since Andrew, but I don't remember seeing almost any concrete block houses with significant structural damage. If there was damage, it was caused by the windows being blown out and letting the wind in, or the roof being ripped up. The walls on the concrete houses held up very well. A big problem was garage doors. Once there was an opening into the house such as the garage or a large broken window, that is all it took.
