Civil Engineering Drawing MCQ’s – Estimation in R.C.C. Structures

1 - Question

What does R.C.C. stand for?
a) Reinforced Cement Concrete
b) Reinforced Concrete Cement
c) Reinforced Combined Cement
d) Reinforced Constituent Cement
View Answer Answer: a
Explanation: When we say concrete in the building trade, we actually mean reinforced concrete. Its full name is reinforced cement concrete, or RCC. RCC is concrete that contains steel bars, called reinforcement bars, or rebars.

2 - Question

The maximum area of tension reinforcement in beams shall not exceed _________
a) 2%
b) 4%
c) 0.15%
d) 1.5%
View Answer Answer: b
Explanation: According to the clause maximum reinforcement-the maximum area of tension reinforcement shall not exceeds 0.04 bD. So, 0.04 bD/bD*100 = 4%.

3 - Question

The diameter of longitudinal bars of a column should never be less than _________
a) 6 mm
b) 8 mm
c) 10 mm
d) 12 mm
View Answer Answer: d
Explanation: Due to buckling we don’t use diameter of longitudinal bars of a column less than 12 mm diameter.

4 - Question

Thickened part of a flat slab over its supporting column, is technically known as _____________
a) drop panel
b) capital
c) column head
d) cannot be determined
View Answer Answer: a
Explanation: Drop panel is used for resisting high shear at the column, drop panels have thickness more than the slab thickness and they are mostly used when the span is large or shear load is high. While column capital is the upper head of the column which is thickened to reduce the punching shear on the column, column capital also reduces the clear span.

5 - Question

The minimum cube strength of concrete used for a prestressed member, is ________
a) 50 kg/cm2
b) 150 kg/cm2
c) 350 kg/cm2
d) 100 kg/cm2
View Answer Answer: c
Explanation: M35 is minimum required concrete for prestressed concrete. Here 35 is in N/mm2. So convert it into kg/cm2. N/mm2 = 10 kg/cm2. So 35 N/mm2 = 350 Kg/cm2.

6 - Question

The number of treads in a flight is equal to __________
a) risers in the flight
b) risers plus one
c) risers minus one
d) risers plus three
View Answer Answer: c
Explanation: The part of the stairway that is stepped on. It is constructed to the same specifications (thickness) as any other flooring. The tread “depth” is measured from the outer edge of the step to the vertical “riser” between steps. The “width” is measured from one side to the other.

7 - Question

For initial estimate for a beam design, the width is assumed _____________
a) 1/15th of span
b) 1/10th of span
c) 1/20th of span
d) 1/30th of span
View Answer Answer: d
Explanation: Beams are traditionally descriptions of building or civil engineering structural elements, but any structures such as automotive automobile frames, aircraft components, machine frames, and other mechanical or structural systems contain beam structures that are designed to carry lateral loads are analyzed in a similar.

8 - Question

A foundation rests on _____________
a) base of the foundation
b) subgrade
c) foundation soil
d) base of the foundation, subgrade and foundation soil
View Answer Answer: d
Explanation: A foundation (or, more commonly, base) is the element of an architectural structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (Geotechnical engineering) in the design of foundation elements of structures.
