2  · Brick walls with a slenderness ratio of up to 6.0 are considered short walls which fail under compression. Walls with a slenderness ratio greater than 24 are unstable and are prohibited. To find the reduced load that can be carried on walls with a slenderness ratio greater than 6.0, we use a reduction factor explained in the Section above

 · Bond-beam masonry unit has a reduced-height across webs and the hollow core is afterwards grouted solid. It is typically one course tall and can be found at locations like top of foundation walls, top of walls, floor-diaphragm connection. In highly active seismic zones, you may need to use intermediate bond beams.

Load bearing masonry walls are constructed with bricks, stones or concrete blocks. These walls directly transfer loads from the roof to the foundation. These walls can be exterior as well as interior walls. The construction system with load bearing walls are economical than the system with framed structures. Fig: Load Bearing Masonry Wall

They have a density is 1700 to 1800 kg / cu.m and compression strength of 3.5 – 5MPa for economic production (transport, tax). Also, have better thermal properties, ease of chisel installation of services (electrical and plumbing) is less labor-intensive and less time-consuming. Cons: They are high amplitude variations.

AS3700, Masonry structures, is the main standard for design, material and construction of masonry structures. AS4773, Masonry in small buildings, is a "minimal calculation" standard for use by small building designers and specifiers.

 · The failure of masonry walls under in-plane loading is generally caused by one of (a) compressive failure at the toe of the wall, (b) flexural failure or (c) shear failure along the mortar joints. These effects can also be described as (a) rocking failure, (b) diagonal tension cracking and (c) bed-joint sliding as shown in (Fig. 1 ).

 · 1. That there are three main types of walls used to building housing – masonry, monolithic and frame walls. 2. How masonry walls are built and what to watch out for when inspecting these walls 3. How windows, doors and roof anchors are built into masonry walls 4. Water penetration and exterior walls – making these walls watertight. 5.

 · Masonry walls can be of several different types: Veneer (wall system provides cladding and only resists transfers wind loads to a structural backup) Structural/Load Bearing Wall (can be cladding but also provides load bearing system) Water penetration through exterior masonry elements exposed to rain should be anticipated.
