During frame excursions that result in compressive loading of the brace, the brace buckles out-of-plane of the frame forming plastic hinges in the gusset plates, beyond the ends of the connectors, and a plastic hinge at the center of the brace. If you watch carefully during frame excursions that result in tensile loading of the brace, you can actually see the brace get narrower (dilate) as it yields.
I can't quite make out what's happening, is the strut moving in and out of the plane and why don't they simulate the movements back and forth like an earthquake event.
