The minimum number of main steel bars provided in R.C.C. Column

• Rectangular Columns is 4

• Circular Columns is 6

• Octagonal Columns is 8

• All the above

The diameter of longitudinal bars of a column should never be less than

• 8 mm dia.

• 10 mm dia.

• 12 mm dia

• None of These

An R.C.C. beam not provided with shear reinforcement may develop cracks in its bottom inclined roughly to the horizontal at -

• 35°

• 45°

• 55°

• 60°

Design of R.C.C. simply supported beams carrying U.D.L. is based on the resultant B.M. at -

• Supports

• Mid Span

• Every Section

• Quarter Span

The amount of Reinforcement for main bars in a Slab, is based upon

• Minimum Bending Moment

• Maximum Bending Moment

• Maximum Shear Force

• Minimum Shear Force

The minimum % of reinforcement of the gross sectional area in slabs for HYSD bars, is

• 0.10 %

• 0.12 %

• 0.15 %

• 0.13 %

The horizontal portion of a step in a stairs case, is known as

• Rise

• Flight

• Winder

• Tread

Design of R.C.C. cantilever beams, is based on the resultant Moment at

• Fixed end

• Free end

• Mid span

• Mid span and Fixed support

In a singly reinforced beam, if the permissible stress in concrete reaches earlier than that in steel, the beam section is called

• Under-reinforced section

• Over reinforced section

• Economic section

• Critical section

An under-reinforced section means

• Steel is provided at the under side only

• Steel provided is insufficient

• Steel provided on one face only

• Steel will yield first
