Mechanical Performance of Built-Up Columns Composed of Four Cold-Formed Square Steel Tubes
This study presents an experimental investigation into the mechanical performance of built-up columns composed of four cold-formed square steel tubes under axial load. The four tubes were assembled together with several C-shaped connectors through two self-tapping screws in each junction. The influe...
