What is slip-critical connection?

A slip-critical connection is a type of bolted connection that is designed to resist slip between two or more connected members. The connection is typically used in structures that are subject to high loads, such as bridges, buildings, or other heavy infrastructure. The bolts used in a slip-critical connection are tightened to a specific torque to ensure that the connection resists both shear and tension forces. The connection is designed to remain intact even when subjected to intense vibration or severe dynamic loading. Slip-critical connections are critical to ensure the structural reliability and safety of high-load structures. They are commonly used in construction projects across the globe. The requirements for slip-critical connections are typically defined by national or international building codes and standards.
