Design Of Masonry Structures Set 1

For masonry work with solid bricks, consistency of mortar should be

Minimum thickness of stiffening wall for 1 to 3 storeys shall not be less than

The thickness of each leaf of a cavity wall shall not be less than

Water retentivity for brick masonry should not be less than

For earthquake resistant masonry buildings, the vertical distance between openings one above the other in a load bearing wall shall not be less than

For earthquake resistant masonry buildings, where seismic coefficient is less than 0.08, the horizontal distance between two openings shall not be less than

In the case of panel wall subjected to horizontal loads at right angles to the plane of the wall, with the mortar not leaner than Ml type, tensile stress in bending in the vertical direction may be allowed to the extent of

Full restraint is provided by
(i) Foundation footing of a wall
(ii) Timber floor spanning on the wall and anchored to the wall
(iii) RCC slab with a minimum bearing of 10 cm on the wall

Consider the following statements:
A high lime content in a composite cement-lime mortar results in
1. Slow hardening.
2. Quick setting.
3. Weaker mortar.

For strengthening a 50 m long and 5 m high straight compound wall built in brick work, which one of the following would be most suitable?
