The initiation time for reinforced concrete (RC) members were researched along coast under chlorine salt erosion and climate. Based existing chlorine erosion life model

as temperature and relative humidity were considered

the initiation time for RC members were calculated. Then the probability distribution of the initiation time was given for RC members along coast in southeast china by using simplified probability analysis. The results showed:① The effect on initiation time from relative humidity should not be ignored; ② The factors

such as relative humidity influence coefficient  f ( h ) 

chloride ion diffusion delay coefficient  m

chloride ion diffusion reference coefficient  D



and concrete cover thickness  X

had more obvious influence on initiation time. This would be useful for structure strengthening

maintenance

and remaining life prediction.
