Seismic per ASCE 07 vs the Richter scale Seismic per ASCE 07 vs the Richter scale IFRs (Petroleum) (OP) 21 May 11 21:22 I have completed a seismic analysis of a structure and the client wants to know what the earthquake intensity would be on the Richter scale. Is it possible for me to give him an answer? RE: Seismic per ASCE 07 vs the Richter scale MiketheEngineer (Structural) 22 May 11 11:06 I know of no correlation. But I would think there might be one.The codes are just looking at accelerations - so there must be some type of comparison.Maybe a Google on Richter scales would give you an idea of what accelerations to expect based on the R number. RE: Seismic per ASCE 07 vs the Richter scale MiketheEngineer (Structural) 22 May 11 11:08 And don't forget the codes are only based on making a building "survivable" - in other words in theory everyone could walk out unhurt. That said, the building may still be a complete and worthless wreck.
