Abstract:
viewpoints of various design codes about vertical component of ground motions is reviewed. Design codes that have been reviewed in this study are: Iranian codes for seismic design of roads and railway's bridges, Caltrans, Euro Code8, AASHTO , AASHTO Seismic Isolation Guide Specifications , AASHTO LRFD Bridge Design Specifications, ASCE ,IBC2012 and UBC97. Then a database consists of 31 near fault earthquake records is gathered and individual and mean and mean +/- standard deviation response spectra plotted for selected 31 earthquakes and by comparison with standard spectra's is showed that usual assumption that vertical component spectrum equal to 2/3 horizontal spectrum isn't correct in short period regions.
