Joint Performance of Beam Using Longitudinal Drift Pinned Joint

Key Points

• This research aims to assess the applicability of existing yield moment and rotation stiffness formulas for longitudinally pinned joints in beams.
• Evaluation of yield moments and rotation stiffness in beam joints using steel plate inserted drift pins.
• Investigation of the relationship between material thickness, drift pin diameter ratio, and brittleness.
• Experimental comparisons of estimated and actual compressive stresses in joints.
• Yield moment calculations tended to be higher due to local crushing at the joint interface.
• Incorporating compressive stress improved the accuracy of yield moment estimations.
• A larger l/d ratio in drift pins increased the likelihood of brittle failure, although design placement had a greater impact.
