Frame26 – Moment and Shear Hinges

Example Description

This example uses a horizontal cantilever beam to test this model moment and shear hinges in a static nonlinear analysis. The cantilever beam has a moment (My) hinge and a shear (Vz) hinge at its fixed end. A vertical load, P, is applied to the cantilever and increased until the vertical tip deflection, Uz, equals 2". Two models are used in the example. Model B applies a default auto subdivide hinge overwrite to the line object containing the hinge whereas Model A does not.
Multiple states are saved for the analysis with the minimum number of saved states set to 6 and the maximum number of saved states set to 10. The tip deflection, Uz, and tip rotation, Ry, for several of the saved states (identified on the next page) are compared with independent hand calculated results.
Important Notes: Bending and shear deformations are included in this example. Also, in this model frame hinges are only active in nonlinear static and nonlinear direct time history load cases. The hinges are ignored in all other types of load cases
