For example, for steel portal frames, the portals are likely to be still in elastic range under seismic actions at ULS and its damping   experimental setup for a real scale steel building made of dual Eccentric braced frame having removable links.

This provides longitudinal strength for sidewall bays. 6 Roof & Wall Bracing 6.1 GENERAL Portal frames resist transverse wind forces by in-plane flexure, but longitudinal wind forces acting on the end walls must be transferred via roof bracing to the side walls and thence to the footings as shown in Figure 6.1. Roof and wall bracing often consist of panels of double diagonals as shown in Figure 6.2. Portal bracing is essentially two vertical steel members welded to the vertical columns, with a horizontal header member attached to the vertical members spanning across the top of your framed opening. Portal frames allow for flexibility in placement of framed openings; however, each portal frame costs a few hundred dollars more than regular “X” bracing. A portal frame is a I-shaped sub-frame consisting of two columns and a rafter placed between the two adjacent mainframe columns in a bay.

Association) But the metal, plastic and glass industries are in- vesting more in bracing talent,” said James Savage.

The rest of the building can still be constructed according to NZS 3604. The specifically designed bracing elements are often different bracing systems rather than light timber -framed sheathed walls.

Portal frame structures can be constructed using a variety of materials and methods. These include steel, reinforced concrete and laminated timber such as glulam.

Steel Framed Structures - R Narayanan - Bok 9780853343295

If you wanted to put 2 large framed openings in ONLY the Sidewall spaced at 2 Bays of 30’ each. A Portal Frame would be used in lieu of X-Cable Bracing in Bay 1, as shown above. Getting Creative with Bay Spacings A Portal Frame would be used in lieu of X-Cable Bracing in Bay 1 or 2, if you desire each of 2 Bays of 30' to have a framed opening.
