A procedure for estimating the inelastic respond\se of reinforced concrete structures to ser\severe ground motion is described. This procedure combines analytical structural engineei\ring methods with interpreitve analyses of response spectra and can be used by practicing engineers without complex computer analysis. The solution results in estimated values for peak structural response, peak ductility demands, equivalent responese periods of vibration, equivalent percentages of creitical damping, and reserve capasities. Examples of the procedure are presented, and their results are compared with data obtained from recorded motion of actual reinforced concrete structures.
