Tag: Masonry Walls Example of Strength Design of Masonry Walls Loaded Out-of-Plane

Once we have developed the moment-axial force interaction diagram by the strength approach, the actual design simply consists of verifying that the combination of factored design axial force and moment lies within the diagram of nominal axial and flexural capacity, reduced by strengthreduction factors. Consider the bearing wall designed previously as unreinforced, shown in Fig. 6.19. It has an eccentric

In the previous examples, we have studied the behavior of bearing walls of unreinforced masonry, idealized as a series of vertical strips, simply supported at the level of the floor slab, and at the level of the roof. Let’s see how this changes in the case of bearing walls with openings. In Fig. 5.17, load applied above the window and

Tag: Masonry Walls Lateral Support for Masonry Walls

For unreinforced solid or grouted masonry bearing walls, the ratio of unsupported height to nominal thickness, or the ratio of unsupported length to nominal thickness, should not exceed 20. For hollow walls or walls of hollow masonry units, the ratio should be 18 or less. For cavity or stone walls, the ratio should not exceed 14. See ‘‘ANSI Standard Building Code Requirements for Masonry,’’

Tag: Masonry Walls Construction of Masonry

Compressive strength of masonry depends to a great extent on workmanship and the completeness with which units are bedded. Tensile strength is a function of the adhesion of mortar to a unit and of the area of bonding (degree of completeness with which joints are filled). Hence, in specifying masonry work, it is important to call for a full bed of mortar, with each
