This isn't really contradicting what you're saying, but I remember seeing something on TV about the construction of...maybe it was Taipei 101, the tallest building in Taiwan. They mentioned that designing for earthquakes and typhoons can actually be opposing goals. Typhoon winds tend to be a more constant load, therefore you want the building to be stiff enough to prevent being blown over. But earthquakes are oscillating loads, so you want a structure nimble enough (or putting the whole thing on shocks or rollers or using some oscillation dampening system may accomplish a similiar thing) to prevent the load from cracking the building in half as it changes directions quickly.
