4
5
6
8
Longitudinal bars in columns should be placed
At the centre

Randomly
Only at corners
Longitudinal reinforcement in columns is mainly used to resist
Shear
Tension
Compression
Temperature stresses
Transverse reinforcement in columns is provided in the form of
Stirrups
Lateral ties or spirals
Bent-up bars
Distribution bars
The main function of lateral ties is to
Increase column height

Diameter of lateral ties should not be less than
4 mm
6 mm
8 mm
10 mm
In rectangular columns, longitudinal bars are generally arranged
At mid-sides only
At corners and mid-sides
At centre only
Randomly
Equal distribution of reinforcement on all sides of a column ensures
Economy only
Uniform stress distribution
Reduced cover
Easy concreting only
Clear cover to column reinforcement as per IS 456 should not be less than
20 mm
25 mm
40 mm
50 mm
Lapping of longitudinal bars in columns should be done
At mid-height
Near beam-column junction
In zones of minimum stress
At footing level only
SP 34 mainly provides guidelines for
Structural analysis
Load combinations
Detailing and drafting practice
Mix proportioning
Footings are structural elements that
Support beams
Transfer column load to soil
Connect slabs and beams
Reduce column height
The most common type of footing used for RCC columns is
Pile footing
Raft footing
Isolated footing
Combined footing
Reinforcement in isolated footing is mainly provided at
Top face
Bottom face
Side face
Centre
Clear cover to reinforcement in footings should not be less than
25 mm
40 mm
50 mm
75 mm
Footing reinforcement is generally provided in
One direction only
Two directions perpendicular to each other
Circular pattern
Diagonal direction
Column bars are extended into footing for
Appearance
Load transfer and anchorage
Reducing footing size
Reducing concrete quantity
Development length of column bars in footing ensures
Proper bonding
Reduced cover
Reduced bar diameter
Less spacing
Drafting of columns and footings generally includes
Plan only
Elevation only
Plan, elevation, and sectional details

Supports
Corners
Mid span
Edges
Maximum spacing of main reinforcement in slabs should not exceed
2 times slab thickness
3 times slab thickness
5 times slab thickness
10 times slab thickness
Slab reinforcement drawings generally include
Plan only
Section only
