The issue I am having is that whenever I increase the number of legs for my stirrups, the area of steel required also increases to the point where increasing the number of legs is just not advantageous. I&#39;m designing the cap for shear and torsion along with magnified moments. I have attached a picture of the output for the shear and torsion design. On the left is the result from using stirrups with 2 legs and on the right is results from using 4 legs. The same bar size and spacing was used.&nbsp;</p> <p><img alt=" " src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/5930/4578.Capture.JPG" /></p> <p>Is there&nbsp;any particular reason this is happening? I&#39;ve made multiple stand-alone substructure files thinking that a new file would solve the issue, but they&#39;ve all had this issue. Any help will be greatly appreciated.</p><div style="clear:both;"></div>
