1 : Risk-Targeted Maximum Considered Earthquake Spectral Response Accelerations

The Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations of the 2020 NEHRP Recommended Seismic Provisions and 2022 ASCE/SEI 7 Standard are derived from the data files in the 'Child Items" below, organized by geographic region. For each spectral period and site class, the MCER spectral response acceleration (SaM) is calculated via the following equation: SaM = min[ Sa;RT , max( Sa;84th , Sa;DLL ) ] where Sa;RT = risk-targeted spectral acceleration Sa;84th = 84th-percentile spectral acceleration Sa;DLL = deterministic lower limit spectral acceleration The deterministic lower limit spectral accelerations, which do not differ across the geographic regions, are provided in the [...]
