Bolted connections are designed for which of the following interactions?

• A. Temperature resistance
• B. Corrosion resistance
• C. Fire rating
• D. Shear, bearing, and slip

Answer: (D)

Bolted connections transfer load primarily through three interactions: shear on the bolt, bearing at the bolt holes, and, in slip-critical cases, friction that resists slip. The bolt itself carries the shear force that tries to slide the connected plates past each other, while bearing occurs where the bolt shank presses against the hole edges and surrounding material, controlling deformations and strength. In connections designed to prevent movement, pretension creates friction that helps resist slip, so slip resistance is also a key design consideration. Temperature resistance, corrosion resistance, and fire rating are important environmental and material considerations that influence material selection, coatings, and protection details, but they do not define the main load-transfer interactions of a bolted connection.
