English Abstract

Masonry units (brick, and un-reinforced concrete blocks) constitute a major construction material in Iraq (both northern, southern, and Kurdistan regions), in addition to other materials such as reinforced concrete (RC) and steel.

In most applications, the masonry units will be connected to a structural framing system that consists of columns, beams, and roofs.

Therefore, the masonry units are mainly subjected to lateral loading, such as wind pressure, and those forces govern the design of the masonry system.

At present, structural engineers and designers in Iraq, rely on empirical methods or engineering judgment to design masonry units.

Such methods don’t have rational basics, and in most times yield an over conservative design.

The weak economic situation of Kurdistan region and entire Iraq, urges researchers to seek efficient design methods that reduce labor, equipment, and material costs, while provide a safe usage.

This paper presents a guideline on designing masonry members subjected to lateral loading based on the yield line theory and ultimate load strength.

First, the members are analyzed by the yield line method which can cover a wide range of boundary conditions and special configurations such as openings.

Second, the section capacity of the masonry units is determined according to ultimate strength state, following (ACI 530-05, 2005) and NCMA TEK specifications.

The ultimate strength method is chosen because it provides a safe and an economic solution for the design of masonry members.
