Studies were carried out to investigate the cracking properties of the tension zones of actual RC bridges. Crack spacings and crack widths of three different types of RC bridges were measured and statistically examined. Experiments using RC specimens were also carried out to evaluate the influences of tension and drying.The spacing and the width in bending zone of actual RC bridges comform well to logarithmic normal distribution. A relation W0.95 (95% fractile in the distribution of crack width)=aL+b was observed. Where a and b are coefficients and L is crack spacing. And according to the drying of concrete, both a and b increased. A formula giving the maximum crack spacing and maximum crack width of actual RC bridge was proposed.
