The purpose of this study is to compare the ultrasonic pulse velocity before and after core compression test of steel fiber reinforced concrete using the ultrasonic pulse velocity method. The correlation between the column member ultrasonic pulse velocity before core test, the column member ultrasonic pulse velocity after core test, and the compressive strength of the core specimen were analyzed by fabricating a steel fiber reinforced concrete hollow column member.
