• Both flanges of the beam of steel frames that transfer moment must be supported at certain intervals. The aim here is to support the beam laterally to prevent buckling and to allow the formation of plastic hinges in areas whose capacity is preserved. In this way, the entire capacity of the beam is used.

  • In accordance with the condition given in Eq. 9.3, it should be supported against lateral buckling with lateral support elements.

  • In steel frames where reinforced concrete slabs work as a composite with steel beams, this condition is not required for the flanges of the beams connected to the reinforced concrete slabs.

  • ideCAD Structural applies and reports this control automatically.
