Analytical behaviour of concrete-filled double skin steel tubular (CFDST) beam-columns under cyclic loading
AbstractConcrete-filled double skin steel tubes (CFDST) have a great potential to be used in the construction of bridges and buildings. Limited information is available on the models for the moment (M) versus curvature (ϕ) response, and the lateral load (P) versus lateral displacement (Δ) relationship of these columns subjected to axial load and cyclically increasing flexural loading. A mechanics model is developed in this paper for CFDST beam-columns subjected to constant axial load and cyclically increasing flexural loading. The predicted cyclic responses for the composite columns are in good agreement with test results. Based on the theoretical model, parametric analysis was performed on the behaviours of moment (M) versus curvature (ϕ) response and lateral load (P) versus lateral displacement (Δ) relationship for the composite columns. Finally, simplified models for the moment (M) versus curvature (ϕ) response, and the lateral load (P) versus lateral displacement (Δ) relationship were suggested.
