A wall pier can be made from a combination of both area objects (shell elements) and line objects (frame elements). To report output forces for wall piers or to design wall piers, first specify a label, then assign the name to selected objects.
Click the Define menu > Pier Labels command to access the Pier Labels form to add a new pier label to the model.
Type a name in the Wall Piers edit box.
Click the Add New Name button.
Note: The Pier Labels form also displays when the Modify/Show Definitions button is clicked on the Frame Assignment - Pier Label form.
Highlight a Wall Pier label, type a new name in the edit box and click the Change Name button to change the pier label.
Highlight a name in the Wall Piers display list and click the Delete Name button to remove a Wall Pier label from the model.
