Dynamic behavior of CHS-SHS tubular T-joints subjected to low-velocity impact loading

Welded steel tubular structures are easily exposed to impact loading which may cause devastated damage firstly to their connecting joints. The critical joints determine the dynamic mechanical performance of the structures in those unexpected catastrophes. This paper describes an experimental and numerical impact investigation on dynamic behavior of CHS-SHS tubular T-joints, made up of a circular hollow section (CHS) brace and a square hollow...
