To apply these criteria both various earthquake levels and limit design parameters for each level has to be used. Main objective of this work was to determine occasional earthquake level for design of buildings in Peru. Buildings were analyzed subjected to these occasional movements in order to evaluate response (damage) and evaluate various proposals of design parameters for this seismic level. Working with the performance based approach, maximum firm ground accelerations, elastic design spectrum and uniform hazard spectrum were obtained for a 72 years return period, considered occasional (ATC-40) and service earthquake (Vision 2000). What is remarkable is that very high acceleration levels were found for occasional earthquake (half of severe earthquake) based on Peru’s seismicity as compared to ISO 3010 specification (one fifth of severe earthquake for 20 year return period). On the other hand maximum ground acceleration was used for scaling the most significant earthquake records in Peru. Uniform hazard spectrum was considered as the objective design spectrum, in such a way that spectra for the records considered be compatible with this objective spectrum. Additionally a summary of analytical and experimental work on reinforced concrete, masonry and steel building response when subjected to lateral loads were revised in detail. Cracking is used as elements damage indicator and drift as damage level indicator on the structural system. Emphasis was made on damage under occasional level earthquakes. Conceptual and methodological aspects relating evaluation of seismic damage on buildings have been analyzed. For this purpose incremental nonlinear static analysis and elastic time history analyses were used. Damage evaluation was applied to an eight story shear wall building designed for strength according to Peruvian seismic standard (E030). Time history elastic analyses were performed using parameters of the occasional earthquake and to determine maximum demands in the nonlinear range and nonlinear incremental static analysis (pushover) was used. Response was acceptable within range of “immediate occupancy”
