In reliability-based seismic design of a structure, it is important to estimate the maximum response of an inelastic oscillator corresponding to a prescribed exceedance probability during a reference period. This paper first investigates the accuracy of the use of either a uniform hazard spectrum (UHS) or a conditional mean spectrum along with an equivalent linearization technique to estimate the response. Then, a new approximation method is proposed using UHS along with a modified Capacity
