Design/Construction Guide: Diaphragms and Shear Walls
www.osbpanel.orgdiaphragms and shear walls are used in the lateral design of a building, the structural system is termed a “box sys-tem.” Shear walls provide reactions for the roof and floor diaphragms, and transmit the forces into the foundation. An accurate method for engi-neering diaphragms has evolved from analytic mod-
Seismic Design of Precast Concrete Diaphragms
nvlpubs.nist.govdiaphragms can be truss elements or horizontal diagonal bracing, in most cases diaphragms utilize the floor system and are constructed as essentially solid, planar elements made of wood, steel, concrete, or combinations of these. Concrete diaphragms can be conventionally reinforced or prestressed, and can be cast-in-place

4.5 Procedures for Diaphragms - Memphis
www.ce.memphis.eduIt is customary to analyze diaphragms using a beam analogy. The floor, which is analogous to the web of a wide-flange beam, is assumed to carry the shear. The edge of the floor, which could be a spandrel or wall, is analogous to the flange, and is assumed to carry the flexural stress. A free-body diagram of these elements is shown in Figure 4-27.

FLOOR DIAPHRAGMS. - sefindia.org
www.sefindia.orgFLOOR DIAPHRAGMS. Definition and function: A horizontal system (roof, floor or other membrane or horizontal bracing) acting to transmit lateral forces to vertical-resisting elements. The floors and roof of a building, in addition to resisting gravity loads, are also generally designed to act as diaphragms.

Assumed effective width only results in a small shift of neutral axis. Some people suggest increasing tension flange width by 1.5 for shear capacity design and ductility checks.
