The crossbeams may reasonably be assumed to provide full lateral<br />

and torsional restraint at B and C; assume further that ends A and<br />

D are similarly restrained. Thus the actual level of transfer of load<br />

at B and C (relative to the main beam’s centroid) will have no effect,<br />

the lateral-torsional buckling aspects of the design being one of considering<br />

the 3 segments AB, BC and CD separately.<br />
