Civil Engineering : Design Of Masonry Structures QUESTIONS AND ANSWERS :: part1 : 11 to 15

Following Civil Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2014 and IES 2014 examinations :

11.Cement mortars richer than 1 : 3 are not used in masonry because (i) there is no gain in strength of masonry (ii) there is high shrinkage (iii) they are prone to segregation Of these statements

Only (ii) is correct
(i) and (ii) are correct
(ii) and (iii) are correct
(i), (ii) and (iii) are correct

12.Assertion A : For eccentricity ratio exceeding 1/6, 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 give below:

Both A and R are true and R is the correct explanation of A.
Both A and R are true and R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.

13.Rich cement mortars are more liable to cracking as compared to lean mortars because rich mortars have

high shrinkage
less strength
both (a) and (b)
none of above

14.If the eccentricity ratio is more than 1/24, then increase in the permissible stress in the design of wall subjected to eccentric loading as per code is

10%
25%
33 1/3%
50%

15.If H is the height of wall between centres of supports, then the effective height of wall where concrete floors have a bearing on wall irrespective of the direction of span will be

0.75 H
0.85 H
1.0 H
1.5 H
