But the reason behind it may be &#39;CODE ACI&quot;. In design section you have mentioned code as &#39;CODE ACI&quot;. Now depending upon the versions it may change. For example in latest version it is referring to ACI 318 2014. In V8i it may refer some other older version where clauses for torsion were not implemented or guiding. You may also refer release note to know the changes made in different versions of STAAD.Pro.</p><div style="clear:both;"></div>
