Abstract
Accounting for the effects of differences between the moduli of elasticity in compression and tension in the calculation of the strength of reinforced beams with filler of foamy fibrous concrete
Incoming article date: 30.04.2013The article investigates the impact on the normal stresses of inequality of the young modulus for tension and compression in the bending of reinforced beams. Obtained formulas for determination of the bending moments that arise in the fixture, compressed and stretched zone of the aggregate. Found the formula for the normal stresses arbitrarily supported reinforced beams, arbitrary cross section and arbitrarily loaded bending loads. For example, reinforced beams of rectangular cross-section shows the determination of the neutral line and maximum stresses.
