Steel frame is a building technique with a " skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. Standard design practice considers the steel framing as a plane grid or as simply supported framing providing lateral support to the wall. . Figure 3 shows the development of such an arch. CURRIES frames are manufactured for all wall conditions such as masonry, steel stud, wood stud, and poured concrete. The latter was fixed to the wall employing threaded rods and an injectable high performance chemical adhesive which may compromise the reversibility of the strengthening system.
