Abstract: The use of circular hollow sections (CHS) have increased due to its aesthetic appearance and good mechanical properties. This research investigates the behavior of the bolted CHS splices with circular end plates under pure bending moment that allows the use of CHS as long flexural members. Three connections are tested and the corresponding finite element models are constructed. The finite element models are verified with the experimental results and showed acceptable agreement in terms of both ultimate moment capacity and load-displacement curves. Three modes of failure are observed where the first is pure bolt failure, the second is pure end plate yielding while the third is a combination of the two modes where end plate plastifies accompanied by bolt failure. Stiffness is also observed and is found to be greatly affected by the thickness of the end plate.
