Example Description
This example uses a fixed base cantilever column to test static nonlinear analysis with large bending displacements in this model. A concentrated moment, M, is applied at the top of the column equally split between the two top joints. The moment M is increased until the rotation at the top of the column is equal to π radians (180 degrees). The resulting vertical and horizontal displacements of the top of the column and the moment required to create the desired deflected shape are compared with independent hand calculated results.
...
After running the analysis, use the Display menu > Show Deformed Shape command to display the deflected shape. To get the deflected shape to display properly, uncheck the cubic curve option, select the Scale Factor option in the Scaling area of the form, and set the Scale Factor to 1.
