Abstract
The vertical component of the ground motions recorded near sources (within the shortest distance 20krn from fault) of nine earthquakes occurred in Japan, which caused damages, is investigated. The two quantities; the Fourier spectral amplitude ratios and the acceleration response spectral ratios of vertical to horizontal components are analyzed. Also, the effects ofthe vertical ground motions on the non-Iinear response behavior of steel arch bridge are investigated. FinalIy, qualitative recommendations for the seismic design intensity in the vertical direction of near source ground motions are proposed.
