Risk-Targeted Maximum Considered Earthquake Spectral Response Accelerations for the 2015 NEHRP Recommended Seismic Provisions, 2016 ASCE/SEI 7 Standard, and 2018 International Building Code
The Risk-Targeted Maximum Considered Earthquake (MCER) spectral response acceleration (S_S and S_1) values of the 2015 NEHRP Recommended Seismic Provisions, the 2016 ASCE/SEI 7 Standard, and the 2018 International Building Code are calculated from the downloadable data via the following equations:
S_S = min[ S_SUH * C_RS , max( S_SD84th , 1.5 ) ]
S_1 = min[ S_1UH * C_R1 , max( S_1D84th , 0.6 ) ]
where
S_SUH & S_1UH = uniform-hazard spectral accelerations at periods of 0.2 & 1.0 seconds, respectively
C_RS & C_R1 = risk coefficients at spectral periods of 0.2 & 1.0 seconds, respectively
S_SD84th & S_1D84th = 84th-percentile spectral accelerations at periods of 0.2 & 1.0 seconds, respectively
The data cover six distinct geographic regions: 1) the conterminous United States, 2) Alaska, 3) Hawaii, 4) Puerto Rico and the U.S. Virgin Islands, 5) Guam and Northern Mariana Islands, and 6) American Samoa. DETAILED METADATA, ABOUT THE DATA FOR EACH GEOGRAPHIC AREA, CAN BE FOUND IN THE ZIP ARCHIVE TITLED: AllMetadataMCER.zip
