Sei 31 03 Seismic Evaluation Of Existing Buildings ....pdf -

SEI 31-03 says: if Tier 1 flags a problem, you either go to Tier 2 (a more detailed analytical evaluation) or Tier 3 (full structural modeling). She had 30 days left.

Tier 2 is a more rigorous, nonlinear or linear static procedure. Here, the engineer uses the ASCE/SEI 31-03 modeling parameters to calculate the building's Seismic Demand versus its Seismic Capacity . SEI 31 03 Seismic Evaluation of Existing Buildings ....pdf
