Maximum Credible Earthquake
Maximum Credible Earthquake
(OP)
Hello,
I am working on a project, and a comment received on a submission suggested “adding consideration for peak horizontal velocities associate with a maximum credible earthquake and/or operating basis earthquake”. The project is located in an extremely seismically stable area (in the US),and I have never considered seismic factors for any project I have worked on (which is many). Any guidance as to a publication or accepted procedure? I have determined Min and Max SS and S1 from the USGS website. What next?
Thanks

Ss and S1 are modified by site class coefficients Fa and Fv to get the MCE level accelerations Sms and Sm1 for your site. In normal building design we use 2/3 of these values to get the design level accelerations Sds and Sd1. But if they want you to design for MCE, you can substitute Sms and Sm1 anywhere you would use Sds and Sd1 in Chapter 12 of ASCE 7.
