J. Patel et alii, Fracture and Structural Integrity, 72 (2025) 1-14 DOI: 10.3221/IGF-ESIS.72.01 12 For insight into the impact of concrete imperfection on peak axial load carrying capacity of CFDST columns with concrete imperfections, a Strength Index (SI) is defined as the ratio of the peak axial load of CFDST column with concrete imperfection to peak axial load of CFDST column without concrete imperfection are evaluated and summarised in Tab. The ductility of CFDST column test specimens was found to decrease with an increase in both types of concrete imperfections (i.e. circumferential and spherical or rectangular).	cache/fis-5152.pdf	txt/fis-5152.txt
