Direct load carrying capacity of a brick masonry wall standing freely as against when it supports RC slab will be
YOUR ANSWER : ?
YOUR ANSWER : ?
Consider the following statements: The use of relatively weak mortar 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. 2. Will result in reduction of stresses due to differential expansion of masonry units.
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?
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:
YOUR ANSWER : ?
In a cavity wall, both leaves of which are load bearing, the effective thickness is taken as
YOUR ANSWER : ?
Assertion A : For eccentricity ratio exceeding 1/6, effective thickness of masonry will get reduced.<br/>Reason R : For eccentricity ratio exceeding 1/6, there will be tension on one side of the member.<br/>Select your answer according to the codes give below:
YOUR ANSWER : ?
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:
YOUR ANSWER : ?
Minimum thickness of stiffening wall for 1 to 3 storeys shall not be less than
YOUR ANSWER : ?
Minimum compressive strength in N/mm² for H1 type mortar used for masonry is
YOUR ANSWER : ?
If the ratio of center to center spacing of intersecting walls to actual thickness of intersecting wall is more than 20, then the stiffening coefficient for wall proper will be
