Mode II interface constitutive law for concrete substrates strengthened with steel reinforced polymers

A new, effective and economical method has been introduced in the literature for the external strengthening of existing reinforced concrete structures, consisting of an innovative composite material using steel wires, in lieu of traditional carbon or glass continuous fibers, embedded in a polymer matrix. The resulting composite is termed Steel Reinforced Polymer (SRP). The SRP can be externally bonded to a substrate via wet lay-up, using either …
