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
Description
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.
