An approximate method for the estimation of the seismic damage of r.c. multistory buildings is presented. The method is based on the Capacity Spectrum Method and the Inelastic Demand Response Spectra which are obtained with a reduction rule defined from a statistical data analysis. The local damage index was defined with an improved Park & Ang model starting from the pushover analysis of the building and the nonlinear dynamic analysis of the equivalent bilinear SDOF system. The approximate method was applied to r.c. multistory buildings when subjected to earthquake ground motion. The results obtained are compared with those computed using step-by-step time history analysis of the structure.

Abstract
An approximate method for the estimation of the seismic damage of r.c. multistory buildings is presented. The method is based on the Capacity Spectrum Method and the Inelastic Demand Response Spectra which are obtained with a reduction rule defined from a statistical data analysis. The local damage index was defined with an improved Park & Ang model starting from the pushover analysis of the building and the nonlinear dynamic analysis of the equivalent bilinear SDOF system. The approximate method was applied to r.c. multistory buildings when subjected to earthquake ground motion. The results obtained are compared with those computed using step-by-step time history analysis of the structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
