§14.2 Strength

The required strength of members is based on load combinations generated in the seismic provision mode (including the amplified seismic loads).

To facilitate connection design the brace strength (Ry Fy Ag) is reported.

Chevron (V or inverted V) brace frames are not allowed to have braces with Kl/r larger than $4.23\sqrt{E_s/F_y}$.
