Comment: added figure fro spandrels

...

If, for example, you are not interested in either design or output forces for
wall piers P1 and P5 at the Roof level, do not provide wall pier labels for
those area objects.

Wall Spandrel Labeling

Image Added

In Figure a, the upper wall spandrel label S1 is associated with the Roof level and the lower S1 is associated with the 2nd level. The upper wall

spandrel label S2 is associated with the Roof level, the middle spandrel made up of two area objects labeled S2 is associated with the 2nd level,

and the lowest S2 spandrel is associated with the Base level. Because the wall spandrels are associated with story levels, wall spandrel

labels can be repeated at different levels, as shown in the Figure 3.


  • Wall spandrel forces are output at the left and right ends of wall spandrel elements. 
  • Wall spandrel design is only performed at stations located at the left and right ends of wall spandrel elements. 
    Spandrel label shall not be assigned to wall elements when their left or right joints are not aligned vertically. In 
    other words, left and right joints must have the same x and y coordinates, respectively.
  • Each area object that makes up a part of a wall may be assigned one spandrel label (and one pier label).
  • Multiple wall spandrel labels cannot be assigned to a single area object.Wall spandrel labels are used to identify wall spandrels.
  • After a wall spandrel has been assigned a label and an analysis has been run, forces can be output for the wall spandrel and it can be designed.
