Recurrence Relations for the Equilibrium Means of Distributions Arising in Chemical Reactions

E.K. Elsheikh · Sultan Qaboos University Journal for Science · 1997 · 10.24200/squjs.vol2iss0pp77-85

… reaction, the relations provide a convenient means of evaluating the means, variances and other important moments without any need to work out the underlying distributions. As an application, the relations are used to numerically assess-approximate expressions for the means and variances.

AN ASSESSMENT OF THE EFFECT OF CONSTRUCTION ERRORS DURING THE IMPLEMENTATION OF RC T-BEAMS

Elsaid Bayoumi, Ahmed G. Asran, Mohamed A. Eliwa et al. · The Journal of Engineering Research · 2019 · 10.24200/tjer.vol16iss2pp103-114

… sections. The results indicated that the faulty placement of slab reinforcement leads to a lower bending moment capacity of the slab (brittle behavior) and the steel strain of slab decreases as the height of slab reinforcement decreases. The irregularity of the reinforcing bars in concrete slab affects the ultimate lo …

Effective Flange Width for Composite Steel Beams

Talat Salama, Hani H. Nassif · The Journal of Engineering Research · 2011 · 10.24200/tjer.vol8iss1pp28-43

The effective flange width is a concept proposed by various codes to simplify the computation of stress distribution across the width of composite beams. Questions have been raised as to the validity of the effective slab width provisions, since they have a direct effect on the computed ultimate moment as well as servi …
