Foundation MCQs : Here you will find MCQ Questions related to "Foundation" in Construction & Building Materials. These Foundation MCQ Questions Will help you to improve your Construction & Building Materials knowledge and will prepare you for various Examinations like Competitive Exams, Placements, Interviews and other Entrance Exmaniations
Question 1
A foundation is a ____________ portion of building structure
A. lower
B. above
C. middle
D. None of the above
View Answer
Ans : A
Explanation: A foundation is a lower portion of building structure that transfers its gravity loads to the earth.
Question 2
Foundations are generally broken into ___________ categories.
A. 1
B. 2
C. 3
D. 4
View Answer
Ans : B
Explanation: Foundations are generally broken into two categories: shallow foundations and deep foundations.
Question 3
Which of the following is the most common type of foundation used for building construction?
A. Individual footing
B. Isolated footing
C. Combined Footing
D. Both A and B
View Answer
Ans : D
Explanation: Individual footing or an isolated footing is the most common type of foundation used for building construction. This foundation is constructed for a single column and also called a pad foundation.
Question 4
Once the foundation has been packed down tightly, or dried hard, we can begin to build the building superstructure.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Once the foundation has been packed down tightly, or dried hard, we can begin to build the building superstructure
Question 5
Which Foundation is used when the wall carries light loads or when the safe bearing pressure is very high?
A. Simple pad footing
B. Simple Strip footing
C. Grillage footing
D. Strap footing
View Answer
Ans : B
Explanation: In that case, a simple strip footing is provided. The wall directly rest on the concrete base, and no masonry offset are provided since spread is not required.
Question 6
Which foundations are the types of foundation which are spread across the entire area of the building to support heavy structural loads from columns and walls?
A. Raft
B. Mat
C. Both A and B
D. None of the above
View Answer
Ans : C
Explanation: Raft or mat foundations are the types of foundation which are spread across the entire area of the building to support heavy structural loads from columns and walls.
Question 7
In the case of waterlogged area, the loading on the soil is limited to __________ KN/m^2.
A. 160-200
B. 30-40
C. 600-800
D. 50-60
View Answer
Ans : D
Explanation: Water logged areas have very low bearing capacity of soil. Hands to overcome this we cannot use steel beams which may get corroded due to subsoil water therefore Timber grillage Foundation is preferred.
Question 8
_____________ is the method of increasing the bearing power of soil when load coming on the soil is practically uniform.
A. Grillage Foundation
B. Raft foundation
C. Inverted arch foundation
D. Mat foundation
View Answer
Ans : B
Explanation: The raft is design as an inverted RCC roof with uniformly distributed load of soil pressure and supported by walls, beams and columns. This method consists of providing and RCC slab of suitable thickness and with necessary reinforcement with help in increasing the bearing power of soil.
Question 9
To make a foundation, we normally dig a trench in the ground.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: To make a foundation, we normally dig a trench in the ground, digging deeper and deeper until we come to subsoil, which is more solid than the topsoil that is used to grow plants and crops. When the trench is deep enough, we fill it with any strong, hard material we can find.
Question 10
What is the value of angle of response for clay(dry) soil
A. 10 degree
B. 20 degree
C. 30 degree
D. 40 degree
View Answer
Ans : C
Explanation: The depth of footing should also be such that the rate of angle of spread of the load from the wall base to the outer edge of ground bearing does not exceed the permissible value.
