Numerical example | Stresses in steel and concrete
Now we shall proceed with a simple 6 step procedure for determining compressive stresses in steel and concrete. Further in our next article, we shall also solve a numerical using the same method.
Generally, the following data is given for reference with the help of which we can determine the stresses in steel and concrete
Breadth of the beam = b
Effective depth of the beam = d
Area of tensile steel = Ast
Area of compressive steel = Asc
Modular raito = m
Bending moment = M
Six step procedure for determining the compressive stresses in steel and concrete:
Step One:
Find x by using the following formula:
bx.x/2 + (1.5m – 1)Asc (x – d’) = mAst(d-x)
