摘要

•Novel timber-filled steel tubular (TFST) columns are proposed and fabricated.•Short and long TFST columns are tested in axial compression.•Analytical expressions and finite element analyses (FEA) models are developed to explain the test results.•Results suggest that TFST columns can be a potential substitute for concrete-filled steel tubular (CFST) columns.•The proposed product may offer a market to the non-graded (low Modulus of Elasticity) sawn lumbers.
