Large strong motion data base (East- West, North-South, and Vertical) is recorded by the Algerian accelerograph network monitored by the earthquake engineering research center. Two stations, located in near field, are used for this study: Keddara and Boumerdes stations. Results show a high frequency content in near field and a clear underestimate of the RPA99 design spectra in high frequencies. A clear frequency shift is evidenced on the horizontal component compared to the vertical one. Also, a directionality effect is evidenced particularly at keddara station around 10 Hz where the north south mean spectral amplitude is higher than the east west one. Finally, a comparison between Keddara and Boumerdes East-West, North-South and vertical horizontal mean elastic response spectrum shows higher spectral amplitude in Boumerdes up to 8 Hz for both horizontal and vertical components.
