I just started using Steel design parameters...
Pls. help me out to give proper Lx, Ly & Lz values for the beams in model attached.
Some more queries :
1) Whether all Lx,Ly & Lz are required to define in model ?
2) Whether for columns Lx,Ly & Lz to be defined.
3) My live load a live load of 7KN/m2 on fifth floor . How to apply it on the beams?
