Lateral Bracing, Portals, and Sway Frames - Civil …

    https://civilengineeringx.com/structural-analysis/structural-steel/lateral-bracing-portals-and-sway-frames/
    The portal usually is a sway frame extending between a pair of trusses whose purpose also is to transfer the reactions from a lateral-bracing truss to the end posts of the trusses, and, thus, to the foundation. This action depends on the ability of the frame to resist transverse forces. The portal is normally a statically indeterminate frame.

    One method that is useful if you are using intermittent wall bracing is the Method PFH Portal Frame with Holdowns. This method relies on low-deflection holdown anchorage at the bottom, and substantial nailing at the overlap of the sheathing and the header at the top to prevent overturning of the narrow panel.
