Reinforced concrete beams are now commonly retrofitted using externally bonded (eb) fiber reinforced polymer (frp) plates as the technique is both inexpensive and unobtrusive. However, tests have shown that eb carbon frp plates tend to debond at low strains, which can severely limit the ductility or moment redistribution to such an extent that.
Three stages in the life of a reinforced concrete beam reinforced concrete, considered “low‐tech” by some, is actually complex. It consists of two materials, steel and concrete; the concrete can be cracked or uncracked; and the load‐deformation behavior of both the steel and the concrete are non‐linear at failure.
