THE CASE FOR LOAD-BEARING BRICKWORK - Clay Brick

Load-bearing brick structures are basically gravity stable. That is to say, they resist overturning forces by virtue of their self-weight. This is a consequence of the fact that unreinforced brick work, like unreinforced concrete, is strong in compression, but relatively weak in tension. The following structural requirements must be met:

How can we calculate the load bearing capacity of a brick ...

A load bearing capacity is calculated based on the composite compressive strength of the elements used in its construction. A wall, by, and of itself, doesn’t lend itself to a load bearing capacity yield. Why not? Because it doesn’t bear the load ...

Axial Compression and Flexure - Unreinforced Design

Reinforced masonry walls, like their unreinforced siblings, are designed for both axial compression and flexure. Examples include: load bearing exterior walls (subject to wind and/or seismic loads), tall non load-bearing exterior walls (where the self-weight of the wall decreases wall capacity), and walls with an eccentric vertical load.

Unreinforced masonry wall design - CE-REF.COM

Unreinforced masonry walls are often used as load bearing or non-loading interior wall in one story building. Although it is called “unreinforced”, the masonry wall still needs to be reinforced with joint reinforcements. In addition, ordinary and detailed plan masonry walls are allowed as shear walls in seismic design category A B.
