Moment of Resistance of Rectangular Beam
Let NA N A is the neutral axis of section. M ser A sc σ sc d - d 05 b d 2 α ser 1 -. Ultimate Moment Of Resistance Of A Rectangular Section In Bending σcbc is the compressive stress in the concrete at a depth d mm from the top of the beam where Asc is provided. . Therefore z d-x3 Moment of resistance is given by Mr C x z bx σcbc2 d-x3 OR Mr T x z Ast σst d x3 For balanced section the formula is as follows Mr bxc σcbc d xc3 Ast σst d xc3. Tensile stress in the tendon at failure. Modified 16 months ago. Modified 16 months ago Determine ultimate moment of resistance of doubly reinforced rectangular section of size 300 x 550 mm effective having tension reinforcement of 6 bars of 25 mm ϕ and compression reinforcement of 3 bars of 20 mm ϕ. I will write the equation using Limit State Method LSM single-reinforced beam. F_ckgrade of concrete f_ygrade of steel Bwidth of beam deffective depth of beam x_udepth of neutral axis NA from ...
