## 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 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.

C. 1.0 H
D. 1.5 H

## Maximum slenderness ratio of load bearing walls for a dwelling having more than 2 storeys________________?

i) shall not exceed 12 if lime mortar is used
ii) shall not exceed 18 if cement lime mortar 1:2:9 is used
iii) shall not exceed 24 if cement mortar 1:6 is used

the correct statments is ?

A. (i) and (ii) are correct
B. (ii) and (iii) are correct
C. (i) and (iii) are correct
D. (i) and (ii) and (iii) are correct

## Consider the following statements?

1. Masonry in rich cement mortar though having good strength with high shrinkage is much liable for surface cracks.
2. Lime mortar possesses poor workability and poor water retentivity and also suffers high shrinkage.
3. Masonry in lime mortar has better resistance against rain penetration and is less liable to crack when compared to masonry in cement mortar.

Which of these statements are correct?

A. 1,2 and 3
B. 1 and 2
C. 2 and 3
D. 1 and 3

A. 10%
B. 25%
C. 33 1/3%
D. 50%

## Rich cement mortars are more liable to cracking as compared to lean mortars because rich mortars have________________?

A. high shrinkage
B. less strength
C. both (A) and (B)
D. none of above

## 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.
