Code check for EN 1993-1-1 is most of cases wrong when a continious member is divided into several part

Ref present Staad versions and beam code check according to Eurocode 1993-1-1 Equation 6.61 and 6.62. Staad divide all beams at every incoming beam location and it is not possible to join together several beams to get correct buckling lengths. Eurocode 1993-1-1 with Staad will in most of the cases give wrong and underestimated results when the maximum forces, bending moment about strong and weak axis is on several location along the full beam length. It does not help to add longer buckling length for one of the short beams since the maximum moments still can be on another beam member. The Cm factors will be wrong too. When code check is performed in correct way, the code check results will in many of the actual cases give large over utilization.

Its important Staad is updated w.r.t be able to join beams and get correct code check results.
