Uniform‐hazard response spectra—An alternative approach

Abstract

Abstract An alternative method is presented for generating uniform‐hazard response spectra making use of a seismic hazard curve expressing annual probability of exceedance as a function of Peak Ground Acceleration (PGA), a set of normalized (PGA = 1 g ) mean response spectra, and a coefficient‐of‐variation function for the random normalized spectral values in terms of period T . The practice of using mean + 1σ normalized response spectra, scaled to specified PGA levels, is discussed and associated mean return periods are evaluated.
