Retrofitting of Interior Slab-to-Column Connections for Punching Shear Using Different Techniques

Finite element analysis of interior slab‐column connections strengthened by steel angle plates

“…[13][14][15] Next is through strengthening the flexural reinforcement leading to an increase of the effective depth of slab, by bonding fiber-reinforced polymer sheeting or casting an upper reinforced concrete layer. [16][17][18][19][20] The third concept is postinstalled shear reinforcement which was first reported by El-Salakawy et al 21 by inserting vertical shear bolts around the column. This method was then studied further by Wörle, 22 Fernández Ruiz et al, 23 and Adetifa and Polak.…”
