The resultant of the normal stress distribution over the cross section must be equal to the bending moment M acting about the neutral axis (z-axis). The rotational stress is combined with the uniform stresses caused by shear and axial force in the beam, then a resultant is determined using the square root of the sum of the squares. The maximum magnitude of shear stress also occurs at the inside surface. Due to the massive proportions and resulting low concrete stress, low strength concrete can generally be used for the wall construction. After a brief review on the concrete shear strength mechanisms, two very reliable expressions for predicting the shear strength of beams without transverse reinforcement are reported: the one proposed by Bažant and Kim [7], which is valid for Normal strength Concrete (NSC) beams, and the other recently proposed by the authors, which is valid for High Strength Concrete (HSC) beams.

Flexure Formula. the moment resultant of stress "x is dM = - "x y dA then M = - ∫"x y dA = ∫E y2 dA = E ∫y2 dA M = E I where I = ∫y2 dA is the moment of inertia of the cross-sectional area w. Sag Calculation. where h c is EHD film thickness which is obtained by the formula proposed by Chittenden, et al. Welding Calculations Design Rules for calculating the strength of butt and fillet welded joints subject to Direct, Bending and Torsional loadings. The degree of Mullins effect was increased with the increase of the filler addition, but that was different for CB and GCB. The centroid or center of area of a geometric region is the geometric center of an object’s shape.
