>seismic-force-amplification<

seismic-force-amplification  OMEGA  gives a reasonable approximation of
actual
forces acting in an inelastically responding structure. EQ forces are
required 
to be increased by this amount for teh design of elements ie collectors
that 
should not yield. the Elastic response force is about 2xOMEGA
