Are CMU walls load bearing?
Concrete Masonry Units (CMU) The units are often used when masonry is to form a load-bearing wall or an interior partition between spaces within a building. Concrete masonry units can be manufactured in different sizes and with a variety of face textures.
How do you calculate wind load from wind pressure?
Armed with pressure and drag data, you can find the wind load using the following formula: force = area x pressure x Cd. Using the example of a flat section of a structure, the area – or length x width – can be set to 1 square foot, resulting in a wind load of 1 x 25.6 x 2 = 51.2 psf for a 100-mph wind.
What is wind loads on structures?
Wind load is the load, in pounds per square foot, placed on the exterior of a structure by wind. The angle at which the wind strikes the structure. The shape of the structure (height, width, etc.)
How high can you build a 12 CMU wall?
That could produce wall heights of up to 33 feet for walls built with 8-inch concrete masonry units (CMU), 41 feet for 10-inch CMU, and 50 feet for 12-inch CMU. Regionally, 14- and 16-inch CMU are available, which extend possible wall heights even further.
Can a CMU wall have no wind loading?
RE: Interior non-load bearing CMU wall. Wind load DOES NOT GOVERN if there is no wind in the interior. The main framing may have wind loading as greater than seismic, but once again seismic loading still exists on EVERY component, even those with light or no wind.
How tall is a non load bearing CMU wall?
I have an interior non load bearing 8″ CMU wall between concrete floors (11′-0″ floor to floor height). It is connected at base with dowels, however, not connected to the underside of the concrete slab at the top.
How tall should a masonry wall be to resist wind?
A 20 ft (6.1 m) high reinforced concrete masonry wall is to be designed to resist wind load as well as eccentrically applied axial live and dead loads as depicted in Figure 8. The designer must determine the reinforcement size and spacing required to resist the applied loads, listed below.
How are wind loads transmitted to masonry walls?
In such cases, end fixity and two-way bending can be utilized. When wind loads are applied normal to a masonry wall surface, the loads are transmitted to horizontal supports (floors, roofs, beams) and/or vertical supports (cross walls, pilasters). Wall panels are usually assumed to function structurally as thin plates or slabs.
