The name Flexframe says it all; the frame allows for flexible floor plans and the frame shows a flexible behavior during an earthquake. Thanks to its lateral performance capacity, the frame moves with the earthquake rather than staying put, it moves along rather than fighting the ground displacement.
The pictures on the right show a test specimen that was loaded. The deformations were reversible, i.e. the specimen was undamaged after the loading was removed and no residual deformations remained.
