I have two different lateral force resisting systems along my N-S direction of my building. On one end of the building, I have shear walls, on the other, I have concentric cross bracing. I'd like to analyze and distribute my lateral forces without the aid of an analysis software. Usually, for shear walls, I would distribute my lateral forces according to relative stiffness. However, I have no clue how I can go about calculating the relative stiffness of a steel braced frame? How do I determine how much goes into my braced frame and how much goes into my shear wall?
Is it enough for me to assume a beam with supports placed at the location of my lateral system, and the resulting shears would be the force that my LFRSs will experience? I don't like this method at all, but its expediency is very tempting.
Any input is appreciated.
