Code Question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Given:
You have a building located in seismic zone 0
You are using the 1997 or the 1994 UBC

Questions:
What UBC provisions are applicable for seismic zone 0? There is one reference to zone 0 in 1630.1.1.  If zone 0 does not require any consideration, what is the purpose of the reference?

What is the value of Z?  Is it inferred to be 0?  ASCE 7, BOCA, & Standard (all derivatives of NEHRP) list a minimum value of Aa or Av of 0.05.  This work was all derived from the Algermissen Perkins charts.  Why is there a difference between the UBC and the other codes?
