«
»

This set of Building Construction Multiple Choice Questions & Answers (MCQs) focuses on “Load Bearing Walls – Design Considerations”.

1. Which of the following is not a type of load coming on the wall structures?

2. Which of the following reasons is not responsible for setting up stresses in a wall?
a) Its own weight
c) Cement
d) Lateral pressure

Explanation: Stresses are set up in walls by its own weight, by the weight of superimposed loads and by lateral pressure. The resistance to these stresses determines the strength of a wall. More the resistance more is the strength.

a) True
b) False

4. In a masonry wall, the strength of the mortar should be __________ that of the masonry unit.
a) Lesser than
b) Greater than
c) Equal to
d) Greater than or equal to

Explanation: The strength of a masonry wall depends on the mortar strength and the strength of masonry units. While keeping the design considerations of a wall in your mind, it must be noted that the strength of the mortar should be lesser than that of the masonry unit.

5. Weak mortar has __________
a) Only lime
b) Only cement
c) More cement and less lime
d) More lime and less cement

Explanation: Mortar consists of both lime and cement. The strength of the mortar determines the strength of a wall. Weak mortar has more of lime and less of cement.

6. Slenderness ratio of a wall does not depend on __________
a) Height of the wall
b) Length of the wall
c) Mass of the wall
d) Thickness of the wall

Explanation: When vertical loads act on a wall, then the strength of the load intensity depends on the slenderness ratio. The slenderness ratio further depends on the length, height and thickness of the wall. It also depends upon the support conditions.

7. Stability problem results when slenderness ratio is more than __________
a) 30
b) 40
c) 50
d) 60

Explanation: The load capacity of a wall is a stability problem when the slenderness ratio is more than 30. It becomes a stress problem when the slenderness ratio is less than 30.

8. The actual thickness of one brick wall in case of modular bricks is __________
a) 18 cm
b) 19 cm
c) 20 cm
d) 21 cm

Explanation: There are two types of bricks used for the construction of brick walls. These are modular bricks and traditional bricks. The thickness can be actual or nominal. The actual thickness of one brick wall in the case of modular bricks is 19 cm.

9. The nominal thickness of one brick wall in case of modular bricks is __________
a) 18 cm
b) 19 cm
c) 20 cm
d) 21 cm

Explanation: The nominal thickness of one brick wall in the case of modular bricks is 20 cm. Nominal thickness includes the thickness of the mortar while actual thickness doesn’t include the thickness of the mortar.

10. Slenderness ratio is inversely proportional to __________
a) Effective height
b) Effective thickness
c) Effective length
d) Effective height and effective thickness

Explanation: Slenderness ratio depends on the effective length or height and effective thickness. It is directly proportional to the effective length or effective height, whichever is less. And, it is inversely proportional to the effective thickness of the wall.
