Failure Modes of T-Stub

Schematic diagram illustrating the three failure modes of a T-stub connection: Mode 1 complete flange yielding, Mode 2 combined bolt failure and flange yielding, and Mode 3 pure bolt failure.
The diagram displays the three potential failure mechanisms of a T-stub connection under tension. Mode 1 represents complete flange yielding with plastic hinges forming at the flange root and bolt line. Mode 2 shows a combination of bolt failure and partial flange yielding. Mode 3 illustrates the case of pure bolt failure without significant flange deformation.
