A methodology to estimate risk of structural response quantities such as maximum story drift ratio, maximum base shear or collapse is presented. The risk is calculated by means of nonlinear dynamic analysis, using a large suite of ground motions selected and scaled based on the so-called Conditional Scenario Spectra (CSS). The CSS are a set of realistic earthquake spectra with assigned rates of occurrence that reproduce the hazard at a site over 10-2 to 10-5 annual exceedance for periods of 0.1 to 4 seconds. The set of ground motion is thought to represent the seismic history of the site over a few thousand years, and allows estimating the return period of engineering demand parameters (EDP) to evaluate their acceptability. The methodology also serves as an objective platform to compare the seismic response of structural systems. As an example to the methodology, the seismic risk of EDPs of a ductile and a nonductile reinforced concrete shear wall are presented.
