End-Bearing connection is used mainly for which application?

• A. Column Vertical Bars with Square Ends
• B. Horizontal Beam Connections
• C. Shear Transfer in Slabs
• D. Anchoring to Steel Plates

Answer: (A)

End-bearing connections transfer the load of a reinforcing bar by bearing on a surface at the end of the bar. This makes them ideal for vertical column bars, where a square-ended bar sits on a bearing seat and transfers axial load directly into the supporting member (concrete or a base plate) without needing threads, splices, or welds. The bearing surface provides the contact area to resist the load and prevent slipping, which is why vertical column bars with square ends are the typical application. Horizontal beam connections, slab shear transfer, and anchoring to steel plates use other methods (such as splices, shear transfer mechanisms, or bolted connections) and aren’t the primary use of end-bearing connections.
