Question No. 1
Assertion A: From consideration of structural soundness and economy of design, most codes control the maximum slenderness ratio of masonry walls and columns.
Reason R: By controlling the maximum slenderness ratio, failure is by excessive stress and not by buckling. Select your answer according to the codes given below:

(A) Both A and R are true and R is the correct explanation of A
(B) Both A and R are true but R is not the correct explanation of A
(C) A is true but R is false
(D) A is false but R is true

Answer: Option A

Question No. 2
Assertion A: Limiting value of slenderness ratio for a column is less than that of a wall.
Reason R: A column can buckle around either of the two horizontal axes while a wall can buckle around only one axis.
Select your answer according to the codes given below:

(A) Both A and R are true and R is the correct explanation of A
(B) Both A and R are true but R is not the correct explanation of A
(C) A is true but R is false
(D) A is false but R is true

Answer: Option A

Question No. 3
A 200 mm thick brick masonry wall made of modular bricks carries an axial load of 30 kN/m from wall above and an eccentric load of 20 kN/m from the RCC floor acting at a distance of 47.5 mm from the centerline of the wall. The resultant eccentricity ratio is

(A) 0.090
(B) 0.095
(C) 0.100
(D) 0.105

Answer: Option C

(A) 5 cm
(B) 7.5 cm
(C) 10 cm
(D) 15 cm

Answer: Option B

Question No. 5

(A) 3
(B) 5
(C) 7.5
(D) 10

Answer: Option D

Question No. 6
The direct load-carrying capacity of a brick masonry wall standing freely as against when it supports RC slab will be

(A) More
(B) Less
(C) The same in both the cases
(D) 100 %

Answer: Option B

Question No. 7
Assertion A: For eccentricity ratio exceeding 1/6, the effective thickness of masonry will get reduced.
Reason R: For eccentricity ratio exceeding 1/6, there will be tension on one side of the member.
Select your answer according to the codes given below:

(A) Both A and R are true and R is the correct explanation of A
(B) Both A and R are true and R is not the correct explanation of A
(C) A is true but R is false
(D) A is false but R is true

Answer: Option A

Question No. 8

(A) 0 6
(B) 0.75
(C) 0.85
(D) 0.95

Answer: Option C

Question No. 9
For strengthening a 50 m long and 5 m high straight compound wall built-in brickwork, which one of the following would be most suitable?

(A) Providing buttresses at certain intervals
(B) Providing a deeper foundation
(C) Using a richer mortar
