title = "Non-destructive testing of concrete-filled steel tubes using ultrasonic tomography",
abstract = "The concrete-filled steel tubes structure is a common combined structure, widely used in high-rise and super high-rise buildings due to its superior mechanical properties. However, construction irregularities, technical limitations, and the shrinkage of concrete can easily lead to defects such as internal voids and cavities. Therefore, it is crucial to use nondestructive testing techniques to detect these problems in a timely manner. In this paper, ultrasonic tomography is used to study the propagation path of ultrasonic waves under different defective conditions, and to locate the defects by inverting the sound velocity distribution map of the specimen cross-section. This verifies that the multipoint countermeasure ultrasonic tomography method can effectively locate the voids and cavities of concrete-filled steel tubes.",
