Deflection(redirected from deflexion)
Also found in: Dictionary, Thesaurus, Medical, Legal, Wikipedia.
the vertical displacement of a certain point on the axis of, for example, a beam, arch, or frame, or on the medial surface of a shell or plate as a result of a deformation. The deformation may be caused, for example, by the action of a force or by temperature effects. The magnitude of the greatest possible deflection is usually normalized and may define one of the limit states of the structure. The maximum permissible deflections for various structures are given in the Construction Code.
