  2. Diaphragm (structural system) - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_(structural_system)

    The two primary types of the diaphragm are flexible and rigid. [1] Flexible diaphragms resist lateral forces depending on the tributary area, irrespective of the flexibility of the members to they are transferring force to. On the other hand, rigid diaphragms transfer load to frames or shear walls depending on their flexibility and their ...

    A classification for the structural system of a high-rise was introduced in 1969 by Fazlur Khan and was extended to incorporate interior and exterior structures. The primary lateral load-resisting system defines if a structural system is an interior or exterior one. [2] The following interior structures are possible: Hinged frame; Rigid frame

  8. Diaphragm (mechanical device) - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_(mechanical_device)

    In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure , or as a device that vibrates when certain frequencies are applied to it.

  9. Thoracic diaphragm - Wikipedia

    en.wikipedia.org/wiki/Thoracic_diaphragm

    Definition of diaphragm in Blount's 1707 Glossographia Anglicana Nova. The diaphragm is an upward curved, c-shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. [6] The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity. [7]
