DISTRIBUTION OF AVERAGE THICKNESS OF COVER CONCRETE ON EACH MEASURING FACE OF ANY MEMBER IN REINFORCED CONCRETE STRUCTURES

When the average thickness of additional cover concrete in design phase and that in construction phase are separately analyzed for each type of member such as column, beam, etc., it showed an almost normal distribution, respectively. Furthermore, concerning the relationship between distribution of the average cover concrete thickness on each measuring face of any member and the deviation within a member, a tendency was found that the deviation within a member increases along with an increase in the average value while the former remains small as far as the latter is small.
