Refuerzo de vigas de hormigón armado mediante la aplicación de fuerzas exteriores introducidas por predeformación de perfiles metálicos

Abstract

One technique for strengthening flexural members in general, and reinforced concrete beams and slabs in particular, entails caulking the underside of these members with steel shapes. This sort of strengthening is often designed from a passive approach; i.e., until the load is increased, the shapes are either not loaded or are only slightly loaded to some unquantified extent by caulking with steel shims.
