WebMay 30, 2015 · This phenomenon of strength and stiffness reduction is commonly referred to as compression softening. Applying this softening effect to the strut-and-tie model, it is recognized that the tensile straining perpendicular to the strut will reduce the capacity of the concrete strut to resist compressive stresses. WebThe predominant approach in retrofitting existing infills aims at increasing their strength and stiffness, mainly using either composite materials (Fiber Reinforced Polymers, FRP) in strips or sheets, or fiber reinforced mortar (FRCM or FRLM) as external coating.
