Repairing And Strengthening Technology Study Of Frame Structure After Fire

High incidence of fires in people's attention, so that people have attached to it. The fire brings to people not only economic losses, more importantly, on people's lives has created a significant threat, Group of death have occurred, even under high temperature structural damage is the collapse of the major causes of casualties One. Many experts and scholars at home and abroad, reinforced concrete structures under high temperature mechanical properties after the fire detection and identification methods, the structure of the reinforcement after fire methods were studied and analyzed in theory, but also many of the results obtained But after the fire building from the identification of reinforcement has not detected the formation of a precise, systematic, scientific system.This paper conducted a study for the following(1) Component of the mechanical properties after fire were analyzed, including the mechanical properties of concrete, the mechanical properties of steel, reinforced concrete mechanical properties.(2) For reinforced concrete structures after fire calculating the remaining capacity was analyzed.(3) For reinforced concrete structures after fire were analyzed identification methods.(4) For reinforced concrete structures after fire commonly used method of calculation and formula were analyzed, in particular, to increase cross-section method and compared the carbon fiber reinforced paste method.
