In the computation of slenderness ratio, does STAAD take into account varying cross sectional properties along its length in a single unsupported span? I'm having this problem since one of my members failed the slenderness check. The value of KL/ry exceeded 300. See attached for reference. The unsupported length in this problem is from node 269 to node 273 and is braced out of plane of the truss with horizontal strutts at nodes 269 and node 273.
