Round HSS Bolted End-Plate Connections Under Bending Moment

Round HSS end-plate connection tested in flexure

Did you know that when used in beams, Vierendeel frames and cantilever poles, bolted end‐plate connections to round HSS are subjected predominantly to bending? There is a well-developed connection design method for pure axial tension load cases in end plates. But under pure bending, a different connection design approach is necessary. Find out more when you check out the results of Dr. Jeffery Packer’s latest bolted-end plate connection tests for four-point bending, including a design example.
