摘要

•Shear-bending tests conducted on 21 CFCSTs and 6 TRCs.•Detailed discussions on failure modes, deformation curves, and load versus mid-span displacement responses.•Analysis on strain/stress properties of CST and shear-bending working mechanism of CFCST.•Design methods proposed for combined shear-bending bearing capacity interaction relationships of CFCST.
