Total questions: 15
Worksheet time: 11mins
In a fixed RCC beam, maximum hogging moment always occurs at —
Mid-span
Near quarter span
Support
Depends on load type
For T-beams, effective flange width shall NOT exceed —
Clear spacing of beams
c/c spacing of beams
Web width
Depth of slab
Minimum thickness at the edge of RCC footing on soil should NOT be less than —
100 mm
150 mm
200 mm
250 mm
A strap footing is used when —
Soil is strong
Columns are very close
Individual footings overlap
Only bending governs design
In an RCC cantilever beam, main reinforcement must be placed on —
Bottom
Top
Middle
Alternate layers
TRUE/FALSE
In continuous beams, crank bars are replaced with extra top bars of span/4 length near supports (a)
TRUE/FALSE
In isolated column footings, reinforcement is provided mainly at the top surface.
(a)
Mat (Raft) foundations reduce differential settlement. Because the entire load is distributed uniformly over a large area.
Both A & R true and R explains A
Both A & R true but R does not explain A
A true, R false
Both false
Minimum cover for reinforcement in footings exposed to soil is (a) mm.
The moment in a cantilever beam is always (a) at the fixed end.
In T-beams, the slab portion acts as the (a) .
The most economical type of RCC footing is the (a) footing.
Pile caps distribute loads from columns to (a) .
Match the following
Simply supported beam →
Zero moment at supports
Fixed beam →
Cranked bars near supports
Continuous beam →
More than two supports
Cantilever beam →
Hogging moment at free end
Match the following
Isolated footing →
For single column
Strip footing →
For load-bearing walls
Combined footing →
For two close columns
Mat footing →
Supports entire building area
