## RCC Structures Design The width of the flange of a T-beam, which may be considered to act effectively with the rib depends upon

All of the listed here
Centre to centre distance between T-beams
Overall thickness of the rib

## RCC Structures Design Minimum spacing between horizontal parallel reinforcement of different sizes, should not be less than

None of these
One diameter of thinner bar
Twice the diameter of thinner bar

## RCC Structures Design If W is total load per unit area on a panel, D is the diameter of the column head, L is the span in two directions, then the sum of the maximum positive bending moment and average of the negative bending moment for the design of the span of a square flat slab, should not be less than

WL/12 (L - D/3)²
WL/12 (L - 2D/3)²
WL/10 (L + 2D/3)²
WL/10 (L - 2D/3)²

## RCC Structures Design An R.C.C. lintel is spanning an opening of 2 m span in a brick wall. The height of the roof is 2.9 m above the floor level and that of the opening is 2.1 m above the floor level. The lintel is to be designed for self weight plus
