Abstract

See full text

A method for quantitative analysis of a cavity at the top of a concrete-filled steel tube is disclosed. By substitution of the determined inner radius of the steel tube, the thickness of the steel tube wall and the propagation speed of ultrasonic waves in the steel tube and in the concrete, the propagation time of the ultrasonic wave between the top and the bottom of the concrete-filled steel tube enables calculation of the height of the cavity. The method can be used to quantify the cavity height at the top of the concrete-filled steel tube, with small relative errors and high accuracy.
