D = 0.775 a
D = 0.0775 a
D = 0.775 √a
D = 0.775 a²

## RCC Structures Design The width of the flange of a L-beam, should be less than

Least of the above
Breadth of the rib + four times thickness of the slab
One-sixth of the effective span
Breadth of the rib + half clear distance between ribs

6 legged
8 legged
10 legged
12 legged

## RCC Structures Design If longitudinally spanning stairs are casted along with their landings, the maximum bending moment per metre width, is taken as

$\frac{w{l}^{2}}{8}$
$\frac{w{l}^{2}}{4}$
$\frac{w{l}^{2}}{10}$
$\frac{w{l}^{2}}{12}$

## RCC Structures Design According to the steel beam theory of doubly reinforced beams

Tension is resisted by tension steel
Compression is resisted by compression steel
Stress in tension steel equals the stress in compression steel
All of the listed here

## RCC Structures Design If K is a constant depending upon the ratio of the width of the slab to its effective span l, x is the distance of the concentrated load from the nearer support, bw is the width of the area of contact of the concentrated load measured parallel to the supported edge, the effective width of the slab be is

K/x (1 + x/d) + bw
Kx (1 + x/l) + bw
All listed here
Kx (1 - x/l) + bw
