Question

A simply supported reinforced concrete beam of length 10 m sags while undergoing shrinkage.Assuming a uniform curvature of $0.004m^{-1}$ along the span the maximum deflection (mm) of the beam mid-span is

• A. 50

Answer 1

The correct option is A 50

Radius,
$R=\frac{1}{C}=250m$
$OA=\sqrt{{250}^2-5^2}$
$=249.95m$
Deflection $=AA=250-249.95m$
$=50mm$
