Diaphragm (structural system) - Wikipedia
WEBIn structural engineering, a diaphragm is a structural element that transmits lateral loads to the vertical resisting elements of a structure (such as shear walls or frames). Diaphragms are typically horizontal but can be sloped in a gable roof on a wood structure or concrete ramp in a parking garage.

WEBAug 11, 2018 · DIAPHRAGM is horizontal or nearly horizontal system acting to transmit lateral forces to the vertical resisting elements. The term “diaphragm” includes horizontal bracing systems. There are two popular types of diaphragm namely rigid diaphragm and semi-rigid Diaphragm.

WEBThe diaphragm forces are transferred to the vertical resisting elements primarily through in-plane shear stress. The most common lateral loads to be resisted are those resulting from earthquake and/or wind actions.

WEBDia-phragm components such as collectors, drag struts, chords and distributors commonly consist of steel beams whose member selection and connections to the primary seismic force-resisting system (SFRS) are to be properly designed for the required axial load.
WEBA diaphragm acts in a manner analogous to a deep beam or girder, where the panels act as a “web,” resisting shear, while the diaphragm edge members perform the function of “flanges,” resisting bending stresses.
WEBDiaphragm forces. Note that in both cases (ELF and MRS analysis), the base shear, and thus the diaphragm force, includes a reduction due to response modification coeficient (R) to which the building frame system is assigned.

WEBDiaphragms are horizontal elements that distribute seismic forces to vertical lateral force resisting elements. They also provide lateral support for walls and parapets. Diaphragm forces are derived from the self weight of the diaphragm and the weight of the elements and components that depend on the diaphragm for lateral support.

WEBSep 19, 2023 · The diaphragm is an unpaired, dome shaped skeletal muscle that is located in the trunk. It separates the thoracic and abdominal cavities from each other by closing the inferior thoracic aperture. The diaphragm is the primary muscle that is active in inspiration. Contraction of the muscle facilitates expansion of the thoracic cavity.

WEBDec 4, 2014 · Equation 12.10-1 gives the diaphragm design forces as a function of story shear in the story below the diaphragm and the ratio of the weight tributary to the diaphragm to the sum of the weights tributary to all the diaphragms above and including the diaphragm.
