The effects of selection and scaling procedures of earthquake records on the seismic response dispersion of structures and recommendations toward seismic upgrading of codes

Abstract In this study, the effects of selection and scaling procedures earthquake records on dispersion seismic response structures are examined. This is according to Standard No. 2800 code ASCE code. So that during two case studies, seven earthquakes have been selected scaled with spectral acceleration 2800. Besides, a reinforced concrete (RC) bridge 7-story RC building evaluated against earthquakes. The results studies indicate respond differently records. However, in order avoid designers' different decisions align their views choose suitable evolve methods for design structures, end, some recommendations presented. show selecting earthquakes, it crucial consider PGA, magnitude, classified range intensities durations strong ground motion. addition, select paying attention frequency content accelerograms shape spectrum also particular importance. Considering ranges scale depending importance significant. By applying mentioned recommendations, will be improved extent. prevented.
