could anyone explain me
when i start to model a beam in sap2000 and ETAB i find that
-in SAP2000 the beam center line is along the mid section of the beam
-but,in ETAB the beam center line is at top fiber
does it have any bad effect to the result of analysis or design or not?
Can we change...
there is an option in "insertion point" command in SAP and ETAB say "do not transform frame stiffness from offsets from centroid"
the question are:
1-if we check or uncheck this box what will happen?
2-does this option have any important effect on ANALYSIS or DESIGN result?
3-when should we...
