[Dnyan Deshmukh]

In un-cracked reinforced concrete columns the actual bending compressive stress is obtained as -

(a) M / bjd2

(b) M / Z

(c) P / A

(d) M / P.


where M = bending moment. b = width of the column section. jd = lever arm distances. A= area of the transformed section.
Z= sectional modulus of the transformed section. P= axial force and d = distance of steel from the extreme compressive fiber.

The correct Answer Is
(b) M / Z
