| Abstract: | In this paper characteristics of near source earthquakes are introduced and its influences on ductility of RC columns are investigated. Numerical results indicate that the magnitude and frequency content of the vertical ground motions have significant effects on the column ductility demand and pseudo acceleration response. The study confirms that strong vertical ground excitations of near source earthquakes should be considered in seismic design. |
