It is a non-load bearing wall that does not support a floor above, does not participate in the lateral system, and is not a wall that resists out-of-plane exterior wind or seismic Axial load–bending moment interaction diagrams account for the interaction between moment and axial load on the design capacity of a reinforced (or unreinforced) masonry wall. For buildings more than one story high, walls must be at least 8 in. Design of a Load-Bearing Brick Wall: Provides a solved example for designing a load-bearing brick wall, detailing calculations for ultimate design load and safety factors. This article explores the types of load-bearing walls, including masonry, concrete, and framed walls, highlighting their materials and design considerations. 2 Shear walls are critical building elements to resist in-plane loads and are, for masonry, the wind and seismic-force-resisting system. For example, adequate bearing of beams and slabs on walls is essential in a gravity structure to prevent possible failure not only from local over-stressing but also from relative movement between walls and other elements. Reinforced Masonry CMU Design Tutorial with summary sheets and Mathcad worksheets with design examples. Supported beam or lintel can span parallel or perpendicular to wall and be positioned eccentrically if required. When this approach is utilized, the limitations of height, load location, seismic zone, wind loading, the size of any openings and lateral sup-port requirements must be considered. In this guide, we have explored the essential steps required for planning, building, and verifying load-bearing walls. 5 bars at 16 in.
