N2 - To get environmental action information for structural life-cycle design and durability design, the air temperature of most Chinese cities from 1951 to 2009 was employed to analyze the applicability of half normal distribution in expressing freeze-thaw action spectrums. A use of spectrum to predict concrete life under freeze-thaw action was performed as well after compiling the freeze-thaw action spectrum of Harbin. In this paper, weather data such as Beijing, Hohhot, Yining and Zhengzhou were analyzed and results showed that half normal distribution is available for most areas of China. Meanwhile, to account for the effect of freezing temperature, freeze-thaw life of a common concrete in water-saturated state in Harbin was predicted to be only about 6 years based on quantitative analysis of the concrete frost resistance.
