Question
There is a cross-section of reinforced concrete beam, which is given as a representation in the figure. The diameter and number of reinforcement used (3 symbolically shown in the figure), the elasticity modules related to concrete standards, and the largest bending moment values affecting the cross-section, and the cross-section height (d) are given in the Excell file. Concrete shall be deemed not to carry tensile stress. The modulus of elasticity of Steel is 200000 MPA. The cross section width is b = 400mm.
a/ Find the neutral Axis (x) of the cross section
b/ Calculate maximum normal stresses in concrete and steel.
Concrete grade and modulus of elasticity value (Mpa) | Bending moment (kNm) | reinforcement diameter (mm) | reinforcement number | d (mm) |
33000 | 80 | 14 | 5 | 750 |
