| Abstract: | On the basis of the flexural fatigue test of a small porous concrete beam in the laboratory,the probability distribution of fatigue life data is analyzed in the paper,the results of which prove that the fatigue life of porous concrete with a new modifier added is in agreement with the two-parameter WEIBULL distribution.Through analyses and comparison,it is found that the modifier has positive effects on the fatigue performance of porous concrete.And the causes and mechanism of the effects of the modifier ar... |
| Keywords: | porous concrete modifier fatigue life WEIBULL distribution fatigue equation |
