...T. S. Thandavamoorthy This paper presents the failure pattern, the ultimate strength, and the stress concentration factor of unstiffened T-joints obtained from experimental and numerical investigations conducted on them under axial brace compression loading. The numerical modeling was performed...

... and punching shear of the unstiffened joints. Strengths of the internally ring-stiffened joints were found to be almost twice that of unstiffened joints of the same dimensions. A tri-linear stress-strain model that takes into account the strain-hardening characteristics of the material was developed to assess...
