Properties of reinforced concrete steel rebars exposed to high temperatures article pdf available in research letters in materials science 2008 april 2008 with 8,995 reads how we measure reads.
Read MoreThe elongation ratios of s220 steel rebars are higher than s420 rebars depending on the ductile fracture behavior of this steel.After a fire inside the reinforced concrete building, the deflections of the structural members increase with the ductile behavior of the steel reinforcement at high temperatures.
Read MoreConcrete beams reinforced with frp rebars, are sug-gested respectively for the two failure modes.2 crack spacing of concrete beams reinforced with frp rebars is nearly 1.5 times as that of con-crete beams reinforced with steel rebars.The crack width and deflections of concrete beams reinforced with frp rebars can be correctly calculated by.
Read MoreReinforced concrete.Reinforced concrete is a composite material that is characterized by the combination of the high compressive strength of portland cement concrete, and the ductility and high tensile strength properties of steel, which make it an ideal construction material bertolini et al., 2004.

Read MoreThe structural performance of reinforced concrete elements is related to the interface behavior of rebars to concrete.In the last decade several research works were carried out to investigate the bond between fiber-reinforced polymer frp rebars and concrete, however some aspects need further studies in order to obtain reliable design indications.
Read MoreThe serviceability and ultimate strength of reinforced concrete structures are greatly influenced by the strength of the bond mechanism between steel and concrete.The bond ensures that the structure remains in equilibrium under any given load.Oil as a formwork releasing agent on construction sites affects this bond.This paper presents an empirical formula for estimating the bond.
