Abstract
![CDATA[Steel beams are often connected to reinforced concrete (RC) floor slabs by shear connectors in real construction. Extensive studies have been conducted on joints to steel beams with Reduced Beam Section (RBS) but limited research has focused on the joints with RBS composite beams. This paper presents an experimental investigation on the cyclic behaviour of the concrete-filled steel tubular (CFST) column to RBS composite beam joints with through diaphragm. The evaluation of the influence of the RC floor slab and RBS is conducted by testing three half-scale joint specimens, including a joint with steel beams, a joint with composite beams and a joint with RBS composite beams. Combined constant axial load and cyclic lateral load were applied to specimens. The strength, ductility, stiffness degradation and energy dissipation capacity are analysed. It is found that the CFST column joint with RBS composite beams exhibits favourable seismic performance. Although the strength slightly decreases under hogging moment, both the ductility and energy dissipation capacity of joints are improved. This type of composite joint has a good prospect in seismic zones.]]
