Frame28 – Large Axial Displacements✔

Example Description

This example uses a three-hinged arch to test static nonlinear analysis with large axial displacements in this model. A concentrated vertical downward load, P, is applied to the center joint of the three-hinge arch. The load P is increased until the vertical downward deflection at the center joint reaches one foot. The resulting vertical support reaction at joint 1 is compared with independent hand calculated results.

Tested Features

•  Static nonlinear analysis of frame structure with large axial displacements using this model P-Delta plus large displacements option
•  Frame end releases
