Shear strength of concrete

Nov 16, 2014The shear strength of concrete (Canada) is given by the formula: Vc = 0.2 x λ x ᶲc x √f'c x bw x d. Where λ = 1 for normal weight concrete. ᶲc = 0.6. f'c = compressive strength of concrete. bw = width. d = depth. Suppose we have a dowel (say rebar) in the center of a concrete panel with thickness 150mm. If the dowel (15 mm) is placed at
