This paper describes the behavior of joint panels in circular hollow section (CHS) column to beam connections. Eleven connection sub-assemblages were tested to investigate the behavior of joint panels. In addition to the tests, finite element analyses (FEA) were performed to complement the test results. The variables of this study are column diameter to thickness ratio (D/t), aspect ratio of joint panel (H/D) and with/without transverse beam (T.B.). During the test, it has been found, the joint panel with larger D/t ratio (D/f=37,48) failed according to shear buckling, and transverse beam contributes to prevent the buckling. The yield strength of joint panel is predictable by a conventional formula based on the shear flow theorem. Also, the full plastic strength of joint panel gives good agreement to the tests results.
