In ConcreteSection, loads are applied to the model in a service load case. The appropriate service case can be selected in the Service Case drop-down list in the Ribbon | Home tab. Loads may be easier to see and select by rotating the view to get a 3D perspective of the model.

Applying Loads

To apply loads to the cross-section, click the Apply Loads command in the Ribbon | Home tab or right-click and select Apply Loads from the context menu. Once the load is applied, an axial force and moments about the X and Y-axes can be entered using the Project Manager | Modify tab. A positive axial load causing compression of the section. Note: Only one load can be applied to each Service Case and the applied loads are assumed to act through the centroid of the section. Note: The Stress Results and Moment Unity tabs are not available when no loads are present in the model.
