This paper presents a comparison between certain results of previous experimental studies and the nonlinear finite element analysis of a reinforced concrete skew slab. The primary parameters studied were the skew angle and the steel arrangements. The slabs were designed using an elastic stress field under an ultimate design load as an input to the direct design method. A good agreement between the experimental and theoretical results was obtained. Furthermore, a theoretical study was performed on an actual ribbed bridge consisting of two lanes under the effect of traffic loads based on Egyptian code of practice recommendations. The parameter investigated in this analytical study was the skew angle, which was varied from 0° to 45°. Skew angles of 0° and 30° were used to study the effect of concrete grade on the overall behaviour of bridge decks. Compressive strength values of 400, 500, 600, 700, 800 and 900 kg\cm2 were considered for each skew angle. In the theoretical study, the skew angle and concrete grade had a significant influence on the overall behaviour of the slab.
