Engineering Reports, Volume 8, Issue 10, October 2026.Acoustic emission transmission modes for void damage in concrete‐filled steel tubes. ABSTRACT Concrete‐filled steel tubes (CFST) have been extensively employed in large‐scale construction projects as high‐performance composite structural members. Nevertheless, varying degrees of void damage frequently occur in CFST due to construction quality issues ...
