	If slip-critical connections fail (by slipping), they revert to bearing-type connections, with structural forces now transferred through bolt shear and connection plate bearing. Thus a slippage failure of a slip-critical connection is not necessarily a catastrophic failure. However, slippage of a slip-critical connection in columns may lead to column instability. Slippage of a slip critical joint in a roof truss could result in unintended ponding effects.
