Question

A haunched (varying depth) reinforced concrete beam is simply supported at both ends, as shown in the figure. The beam is subjected to a uniformly distributed factored load of intensity 10 kN/m. The design shear force (expressed in kN) at the section X-X of the beam is _____.

65

Solution

The correct option is A 65
$V_{u} = 50 k N$
$M_{u} = 375 k N m$
$d e s i g n s h e a r = V_{u} + \frac{M_{u} t a n β}{d}$

$= 50 + \frac{375}{0.5} (\frac{200}{10000}) = 65 k N$
