A is true but R is false

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

A is false but R is true

Vertical tensile splitting

TRUE ANSWER : ?
YOUR ANSWER : ?

The timber floor not spanning on the masonry wall but properly anchored to the wall gives

Neither lateral nor rotational restraint

Rotational restraint but not lateral restraint

Both lateral and rotational restraints

TRUE ANSWER : ?

YOUR ANSWER : ?

Assertion A : Lime based mortars give higher ratio of brickwork strength to mortar strength as compared to non-lime mortar.Reason R : Lime based mortars have lower bond strength as compared to non-lime mortars.Select your answer according to the codes given below:

Both A and R is true and R is the correct explanation of A

A is true but R is false

A is false but R is true

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

TRUE ANSWER : ?
YOUR ANSWER : ?

Consider the following statements:<br/>1. Masonry in rich cement mortar though having good strength with high shrinkage is much liable for surface cracks.<br/>2. Lime mortar possesses poor workability and poor water retentivity and also suffers high shrinkage.<br/>3. Masonry in lime mortar has better resistance against rain penetration and is less liable to crack when compared to masonry in cement mortar.<br/>Which of these statements are correct?

1 and 3

1 and 2

2 and 3

1, 2 and 3

TRUE ANSWER : ?
YOUR ANSWER : ?

The bending stress in a wall or column subjected to effective vertical load need not be considered, if the eccentricity ratio is

Less than or equal to 1/12

Less than or equal to 1/24

Less than or equal to 1/6

More than 1/24

TRUE ANSWER : ?
YOUR ANSWER : ?

Consider the following statements: The use of relatively weak mortar<br/>1. Will accommodate movements due to loads and, cracking if any, and will be distributed as thin hair cracks which are less noticeable or harmful.<br/>2. Will result in reduction of stresses due to differential expansion of masonry units.

1 alone is correct

2 alone is correct

Neither 1 nor 2 is correct
