how to get the Braced frame column axial load
how to get the Braced frame column axial load
(OP)
How do I get the required axial force on braced frame column? Doesthe expected strenght of brace in compression acting as an additional load to column?If it does then lets say i have 10 ten story building using chevron v brace with a 682 kips expected compression strength and an angle made from the brace and the beam is about 48°, does it make thelowest column has to withstand 682sin48*9 kips + gravity axial load acting on column ? Is it usual to have an axial load around 5000 kips for 10 stories structure?

In general columns take the bending force couple, the chevrons take the shear. You can model this as a 2D frame to see the actual interaction. Model all connections as pinned, and members as appropriately continuous.
Expected strength (as opposed to required strength) of the brace won't matter unless you are in high seismic which is a different discussion.
5000 kips sounds high unless you are asking a whole lot from this braced frame.

@sandman21 yeah thanks for the advice and the correction! And yeah its just an example but about the brace, i found it that i got not so much option in choosing the section of the brace because the restriction of the sections b/t has to meet the 0.3(E/Fy)^0.5 for WF section on the AISC seismic provision
