The specific "seismic design spectrum" proposed by the Algerian seismic design code, namely the "normalized acceleration spectrum", seems to present an anomaly in comparison with other seismic design spectra over the world and with computed spectra, especially in the first branch of the curve, corresponding to the range of short periods, where the spectrum is a decreasing line whereas it must be an increasing one. This anomaly is outlined and confirmed, in one hand, and treated by proposing an appropriate formula instead of the available one, in the other hand. Some numerical applications are made using both available and proposed formula. This work may be considered as a contribution to the revision of the Algerian seismic design code which is continually done in order to make it more realistic and more perfect. Key words: Algerian seismic design code, response spectrum, seismic force.

Granular columns have been used as an effective technique for improving the engineering behaviour of soft clays and loose sand deposits. This paper presents the results of an experimental investigation on sand columns internally reinforced with horizontal wire meshes made of plastic, steel and aluminium materials. Loading tests were performed on prototype reinforced sand columns in a stress-controlled chamber that contained normally consolidated clay. The objective of this investigation was to establish the load-carrying capacity of these columns on the light of the presence and intensity of the reinforcements. The performance of the reinforced sand mass was examined, by direct shear testing, in terms of angle of shearing resistance, strains to peak strength, bearing ratio, and brittleness of the system post-peak. A theoretical model is proposed to predict the load-carrying capacity of these columns. The predicted values by the proposed theory compared well with the results of the present experimental investigation as well as those available in the literature. Design procedure is presented for practicing use
