Axial compressive behavior of square CFST stub columns with local corrosion simulated by artificial notch was studied through the combination of experiments and finite element analysis. Fifteen specimens were fabricated and tested. The experimental results showed that the failure modes and the axial compressive behaviors of specimens with notch were different from the intact ones. Compared with the specimen without notch, the compression strength and stiffness of specimens with horizontal notch and sloping notch degraded seriously while the vertical notch had little effect on the compression strength of specimens. Meanwhile, the finite element model was developed by ABAQUS software, whose accuracy was validated by comparing with the experimental results. Further parametric analyses using the developed FE model were conducted to investigate the influence of different parameters on the compression strength of the axially loaded square CFST with notch. Moreover, a formula was proposed for estimating the axial compression strength of the notched square CFST stub columns. (C) 2020 Elsevier Ltd. All rights reserved.
