Abstract : The analysis method on random time dependence of reinforced concrete material is introduced , the effect mechanism on reinforced concrete are discussed , and the random time dependence resistance of reinforcedconcrete is studied. Furthermore , the corrosion of steel bar in reinforced concrete structures is analyzed. A practicalstatistical method of evaluating the random time dependent resistance , which includes material , structural size andcalculation influence , is also established. In addition , an example of predicting random time dependent resistanceof reinforced concrete structural element is given.
Key words : random analysis ; time dependent resistance ; reinforced concrete
