## RCC Structures Design In a simply supported slab, alternate bars are curtailed at

1/4th of the span
1/7th of the span
1/6th of the span
1/5th of the span

Three times
Two times
Five times
Four times

## RCC Structures Design Long and short spans of a two way slab are ly and lx and load on the slab acting on strips parallel to lx and ly be wx and wy respectively. According to Rankine Grashoff theory

(wx/wy) = (ly/lx)⁴
(wx/wy) = (ly/lx)
None of these
(wx/wy) = (ly/lx)²

## RCC Structures Design If the depth of actual neutral axis of a doubly reinforced beam

All listed here
Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier
Is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier
Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum stresses simultaneously

## RCC Structures Design The load stress of a section can be reduced by

Increasing the total perimeter of bars
Replacing smaller bars by greater number of greater bars
Replacing larger bars by greater number of small bars
Decreasing the lever arm
