Application of the component method to bolted endplate composite beam-to-CFST column joints

Component method can be used to predict the moment-rotation behaviour of a wide range of joint configurations by decomposing the joint into individually basic components. The component method has been adopted in Eurocode 3 Part 1–8 and Eurocode 4 Part 1–1 for the design of steel and composite joints, respectively. However, the design rules given in Eurocode 3 Part 1–8 and Eurocode 4 Part 1–1 are restricted to the steel and composite joints with open section columns, i.e. I- or H-sections. For the joints with hollow or concrete-filled steel tubular (CFST) sections, new basic components are introduced and thus the design rules for the new components are required. This paper aims to provide design guidelines for the application of the component method to predict the behaviour of steel and composite beam-to-CFST column joints.
