Yes / Eccentric compression behaviour of reinforced concrete (RC) columns reinforced by steel-FRP composite bars
(SFCBs) was investigated through experimental work and theoretical analyses. The tension and compression test results
show that SFCBs demonstrate a stable post-yield stiffness. The mechanical properties of the composite reinforcement
have a significant influence on eccentric compression behaviour of the reinforced concrete columns, in terms of failure
mode, crack width, deformation and bearing capacity. Formulae were also developed to discriminate failure mode and to
determine moment magnification factor, bearing capacity and crack width of the columns studied, with the theoretical
predictions being in a good agreement with the experimental results. In addition, parametric studies were conducted to
evaluate the effects of mechanical properties of reinforcement, reinforcement ratio, eccentricity, slenderness ratio, types of
reinforcement and concrete on the eccentric compression behaviour of RC columns. The results show that the
compressive performance is significantly improved by using the high performance concrete, i.e. reactive powder concrete
(RPC) and engineered cementious composites (ECC). / financial supports of the work by the National Natural Science Foundation of China (51678514), the Natural Science Foundation of Jiangsu Province, China (BK20201436), the China Postdoctoral Science Foundation (2018M642335), the Science and Technology Project of Jiangsu Construction System (2018ZD047), the Deputy General Manager Science and Technology Project of Jiangsu Province (FZ20200869), the Cooperative Education Project of Ministry of Education, China (201901273053), the Blue Project Youth Academic Leader of Colleges and Universities in Jiangsu Province (2020), the Six Talent Peaks Project of Jiangsu Province (JZ-038, 2016), the Yangzhou University Top Talents Support Project and the Jiangsu Government Scholarship for Overseas Studies.
