It is very important to evaluate the relation between the specified design strength and the distribution of concrete strength in structural member. In this study, the distribution of concrete strength of core specimen cut from plain concrete columns was investigated and compared to the specified design strength of concrete which was estimated by several equations based on the compressive tests of reinforced concrete columns. The following results are obtained in experiment. (1) The core strength is not affected by the drilling direction of concrete. (2) The core strength shows the lower value at the top of concrete column. (3) The mean value of core strength cut from structural member is nearly equal to the specific design strength of concrete estimated from the compressive test result of reinforced concrete model columns.
