Abstract

Compressive tests on steel tubes with shear keys as end-connection and a parametric work through finite element modeling (FEM) revealed that increasing the shear-key thickness×height (tt×Lt) and tube (thickness tc, width B, and length D) enhances strength and stiffness, whereas raising tube height Lc harms stiffness and ductility. Buckling load equations were proposed, and the findings were compared with strength prediction equations from GB50017, NZS3404, IS800, AISC360-22, EC3-1-1, and CSAS16 standards, which accurately reflect the performance of modular steel structures' grouped columns filled with shear keys.
