     This reminds me of a now famous anonymous quote;
     "Structural Engineering is the art of molding materials we don't 
     wholly understand, into shapes we can't fully analyze, so as to 
     withstand forces we can't really assess, in such a way that the 
     community at large has no reason to suspect the extent of our 
     ignorance."

     It makes me wonder when things get that detailed if we aren't kidding 
     ourselves a bit.  Such information for researchers provides good 
     information to understand the various earthquake phenomena.  For the 
     practicing structural engineer however, even with Performance Based 
     Design 
     concepts, it seems like we are trying to determine the forces to a 
     knats 
     
     rear end when the actual certainty in the force levels is not that 
     good.  I 
     think it gives people a false sense of security.  We should be 
     teaching our 
     young engineering colleagues concepts like redundancy, ductility, 
     tieing 
     structures together, load paths and the like.  There should also be 
     required studies in accuracy v. precision.

     Yes, there are ***32*** NEHRP Maps, two to a sheet, folded and 
     stacked, 
     they
     are ****4-1/4 inches**** high.
     
     Seismic criteria are improving, if you live on the correct side of the 
     street.
