“…According to it, Bazant Z P (1979) , LiuXila (1990) , LiuYaqing (1997) , NiuDitao (1996) , Feliu V and others established the model of steel corrosion respectively. Because there are many uncertainty on concrete reinforcement corrosion [3], the application of neural network forecasting the amount of steel corrosion in concrete, made some work [4].…”

based on the relationship between steel rust expansion force and the amount of corrosion, regarding reinforced concrete as a general continuum with the use of integral model, the finite element analysis models of axial compressive members were set up. Concrete units cracking and crushing were considered by the methods of multi-axial stress William-Warnke five-parameter failure criteria and fracture dispersion mode. For axial compression corroded reinforced concrete structures, firstly under the action of rust expansion force produced by steel corrosion, cracks begin to occur around the steel, then column corner steel cracks emerge by the direction of the protective layer and progressively extend to the entire protective layer. With the increasing of the steel corrosion rate, the ultimate bearing capacity reduces. According to the relationship of the corrosion rate and the capacity reduction, a simple method of calculation was established for corrosion axis of the bearing capacity of compression members.
