Beam Member Axial Force


This force is not for use in connection calc. It's output here for user input connection forces equilibrium check only.
Pbm - Beam member axial force is different from Pb-c - Beam to column interface axial force as shown above.

Pbm - Beam member axial force is from structural analysis output and cannot be used directly in beam end to column connection design as this force is interrupted by brace gusset to beam interface force before beam end reaching the column. This force is actually not needed from user's input for beam end to column connection design.

 
Pb-c - Beam to column interface axial force is calculated from user's input of brace axial forces and trasnfer force using uniform force method. This force is used in the beam end to column connection design.

 
Pbm - Beam member axial force is not needed for the beam end to column connection design and is calculated here for verification purpose only. If it matches the structural analysis output, that means equilibrium is reached and user's input of brace axial forces and trasnfer force are correct.
