Example Description
This example applies construction sequence loading to a three-element frame to test this model staged construction capabilities.
The first construction stage includes frame object 1 only. Stage 2 adds frame objects 2 and 3 to the model. Finally, stage 3 removes frame object 3 from the model.
For each stage of the construction, the vertical reaction at joint 1 and the vertical displacement at joint 2 are compared with independent hand calculated results.
Important Note: Bending, shear and axial deformations are all included in this example. Only the Ux, Uz and Ry degrees of freedom are active in this twodimensional example.
Tested Features
- Nonlinear static analysis using the construction sequence loading option
- Frame end releases
