Wood sheathing in the form of wood structural panels, fiberboard, particleboard and board sheathing can be used as diaphragms and shear walls that transfer loads delivered by wind events to the building's foundation. Rigid, wood-frame construction, meanwhile, transfers lateral loads in the event of high winds. As with
In box design, horizontal diaphragms (e.g., roof and floor systems) work in conjunction with vertical shear walls to support gravity loads, resist lateral loads, and provide structural stability. In wood and light-gauge steel-framed construction, the diaphragms and shear walls (called “braced wall lines” or “braced wall panels”.
Wood: It's the natural choice for the environment, for design and for strong, lasting construction. WOOD. The Natural Choice. NOTICE: The recommendations in this guide apply only . diaphragms and shear walls are used in the lateral design of a building, the structural system is termed a “box sys- tem.” Shear walls provide
A soft story building is a multi story building in which one or more floors have windows, wide doors, large unobstructed commercial spaces, or other openings in places where a shear wall would normally be required. Disadvantages Plate Girder Analogy Behavior of Not competitive with reinforced concrete shear wallsSince
Wind and seismic loads are the most common loads that shear walls are designed to carry. Under several building codes, including the International Building Code (where it is called a braced wall line) and Uniform Building Code, all exterior wall lines in wood or steel frame construction must be braced. Depending on the
In cases where diaphragms comprise structural sheathing, additional design efficiencies can be incorporated to resist loads normal to walls, floor and roofs using the composite stressed skin action developed between the sheathing and the timber frame. The advantages of timber shear walls and diaphragms include:.
A diaphragm is a flat structural unit acting like a deep, thin beam. The term “diaphragm” is usually applied to roofs and floors. A shear wall, however, is a vertical, cantilevered diaphragm. These construction systems can be used when designing a building for lateral loads, such as those generated by wind or earthquakes.
Basic Wood Frame Diaphragm Design Principles form a unit. When diaphragms and shear walls are used in the lateral design of a building, the structure is termed “a box system.” Diaphragm sheathing materials are typically a structural wood panel, such as plywood or oriented strand board (OSB), or architectural steel.
Jun 26, 2014 Wall sheathing also ties the roof, wall, floor and foundation together, increasing the strength of the structure. Figure 1 compares wall deformation and ultimate load capacities for typical construction methods. Wood structural panels reduce wall deformation and provide greater shear or racking load capacity
