@designexpertint: When a column carries more than it was designed for, because someone added a floor or changed the building's use, it cracks, the concrete spalls and the rebar buckles. Steel jacketing strengthens it without demolishing it: shoring, steel angles at the corners, welded battens, epoxy resin, anchorage with plates and bolts, anti-corrosion paint and fireproof mortar.
