Abstract
This paper presents the fire resistance and post-fire test results of eight full-scale concrete filled stainless steel tubular (CFSST) column to steel beam joints with blindbolted connections. The investigated parameters included whether applying fire protection to the steel beam or not, beam load ratio (0.25 and 0.5), steel tube type (stainless and carbon steel tubes) and presence of binding bars or not. The test results show that the joint failure was mainly dominated by flexural failure of the steel beams near the panel zone despite the variation of parameters. But when the beam load ratio was 0.25, the joint specimen with a circular column failed due to axial crushing of the column. In general, the blind-bolted connections demonstrated good workability in fire, and no bolt shank fracture or bolt pull-out failure was observed in any joint test.
