Abstract
A multi-story boxed wall frame system for reinforcement of multi-story structures includes first and second boxed wall frames disposed one on top of the other and connected together. Each boxed wall frame includes first and second columns, and first and second panel zones attached to the respective first and second columns at their top ends. Each of the panel zones includes yielding members and reinforcing structure at least partially bounding the yielding members. The reinforcing structure is configured to concentrate stresses to within the yielding member. A beam extends between the first and second panel zones in each of the boxed wall frames. The boxed wall frame is configured to resolve external forces into shear force in the yielding member such that the yielding members will yield prior to yielding of the beam and the columns.
