Axial compressive behaviour of CFDST stub columns with large void ratio

Journal of Constructional Steel Research, 2021
This paper describes the experimental and numerical study on the axial compressive behaviour of circular-in-circular concrete-filled double-skin steel tube (CFDST) stub columns with large void ratio. Nine specimens with various void ratio (Rv), diameter-to-thickness ratio of outer tube and compressive strength of concrete were tested under axial ...

Harmonic chirp imaging method for ultrasound contrast agent [PDF]

, 2005
Coded excitation is currently used in medical ultrasound to increase signal-to-noise ratio (SNR) and penetration depth. We propose a chirp excitation method\ud for contrast agents using the second harmonic component of the response.
