For a continuous RCC beam, the minimum depth (D) as per IS 456 for medium loading is approximately—
L/10
L/12
L/15
L/20
For isolated slab with no conti nous edge, where is the torsion reinforcement provided
(a)
The effective flange width (Bf) of a T-beam in a continuous slab-beam system is given by—
(L/8) + bw + 8df
(L/6) + bw + 6df
(L/4) + bw + 3df
(L/10) + bw + 5df
In a two-way slab with all edges continuous, torsion reinforcement is provided—
Only at corners free to lift
At corners held down
At mid-span
None of the above
In a combined footing for two unequal column loads, the footing is made—
Rectangular
Trapezoidal
Circular
Square
Main reinforcement in a cantilever beam is provided at the bottom near the free end.
True
False
In a one-way slab, the load is carried predominantly along the shorter span direction.
True
False
Assertion (A): Torsion reinforcement is provided at slab corners to prevent cracking due to negative moments. Reason (R): The corners tend to lift under loading when edges are discontinuous.
A true, R false
Both false
Both true and R correctly explains A
Both true but unrelated
The maximum bending moment in a simply supported one-way slab occurs at the (a) .
For Fe 415 steel, the minimum percentage of reinforcement in slabs using deformed bars = (a) .
In an isolated footing, the thickness at the edge should not be less than (a) mm (on soil).
The main reinforcement in a two-way slab is provided in (a) directions.
For continuous beams, crank distance from the face of the support should be (a) of span.
Match the Slab Type with Its Behaviour
| A | One-way Slab |→ | 1. Load carried in two directions |
| B | Two-way Slab | → | 2. Load carried in one direction |
| C | Flat Slab | → | 3. Supported directly by columns (without beams) |
| D | Waffle Slab | → | 4. Ribbed slab with thin topping slab and two-way action |
