Bolted connections in composite structure
The behaviour of composite connection specimens consisting of studded T-beams in negative bending and encased I-section columns bent about the major axis is examined. Both interior and exterior column connections are tested, with the joint between the major steel components effected with simple bolted joints which would be classified as flexible in the bare steel condition. At interior columns, the ultimate behaviour is almost indistinguishable from that of connections having welded joints, and the full plastic moment of the beam including all the reinforcement is exceeded. At external columns, the strength and stiffness were greatly enhanced by the slab and the concrete casing, but the plastic moment of the beam cannot be transmitted before brittle collapse of the slab. The maximum moment transmitted in these specimens in 0.89 Mp compared with 1.18Mp at interior columns. (DePo)
