Maps of earthquake ground motions for the 2009 NEHRP Recommended Seismic Provisions and the 2010 ASCE/SEI 7 Standard

Description

For designing buildings and other structures to safely resist earthquakes, the 2009 NEHRP Recommended Seismic Provisions and the 2010 ASCE/SEI 7 Standard contain maps of Uniform Hazard response accelerations, risk coefficients, 84th-percentile spectral accelerations, and Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations, all at spectral periods of 0.2-second and 1.0-second. The spectral accelerations are for the direction of maximum horizontal response and a site shear wave velocity (VS30) of 760 m/s, in units of the percent g, the acceleration of gravity. For more information, see Chapters 11, 21, and 22 of the 2009 NEHRP Recommended Seismic Provisions and the 2010 ASCE/SEI 7 Standard.
