approx 20 pages of engineering info here bottom line - very strict construction guidelines have to be followed when building an earthquake resistant building earthquakes can cause up to a 2G load on buildings - that is worse than hitting extreme turbulence in a plane for comparison - fighter jets can take a 9G load - but the pilots will pass out but even worse for a building is a sustained shaking from an earthquake - that "wears out" the steel (my interpretation) - like when you bend a metal spoon back and forth to break it -- You received this message because you are subscribed to the Google Groups "massfire" group.
