Experimental study of structural fire behaviour of steel beam to concrete filled tubular column assemblies with different types of joints

Behaviour of combined channel/angle connections to tubular columns under monotonic and cyclic loading

“…Previous experimental work with reverse channel connections utilised conventional channel sections and bolted end-plates [33]. In the present study, the reverse channel components were obtained by longitudinal cutting of hot rolled tubular sections.…”

“…Despite its potential, there is a dearth of experimental studies on connections incorporating reverse channel components, particularly under cyclic loading. Test results on the fire resistance of four end-plate reverse channel connections have been reported by Ding and Wang [33]. The behaviour was compared with other connection details between open beams and concrete filled tubular columns.…”

Fire performance of blind-bolted connections to concrete filled tubular columns in tension

“…Fire exposure was maintained until the end of the test, when the tensile forces transmitted by restrained beam in catenary action caused the fracture of the connection. Concerning the fire behaviour of beam to CFT connections in realistic structures, five types of joints were studied by Ding and Wang [21] and Elsawaf et al [22]. They demonstrated the importance of the connection flexibility and strength if the full capacity of the beam wanted to be achieved.…”

Response and component characterisation of semi-rigid connections to tubular columns under axial loads

“…Mode 3, in which yielding of the bolts occur 15 (15) with (16) Where is the yield stress of angle, is the effective width of the angle taken as half of the angle width , is the bolt capacity, and the distances and are the effective gauge distances considering the influence of the angle stiffness on the location of the plastic hinges defined by Málaga-Chuquitaye and Elghazouli [28] as:…”

“…Despite its versatility, there is a lack of experimental studies on reverse channel configurations. Ding and Wang [15] compared the fire resistance of four end-plate reverse channel connections with other open beam-to-filled tubular column connection details. This study concluded that reverse channel connections can offer the best structural behaviour and cost-effectiveness among the different details considered.…”
