“…As described above, the effect of core preloading has been experimentally investigated only for the case of uniaxial compressive preloading (without bending moment). Analytical investigation involving preloading effects on jacketed R/C sections is generally lacking; a somewhat relevant studies by Ong and Kang [6] and Liew and Xiong [7] are concerning steel-concrete composite sections with preloading on the steel core. The key objective of the present study is to analytically investigate the effect of combined axial and moment preloading of the core on the strength of jacketed R/C columns.…”

The influence of core preloading on the strength of jacketed reinforced concrete (R/C) columns is analytically investigated. A recently proposed method for arbitrary composite section analysis in biaxial bending and axial load is extended to include preloading actions. A parametric evaluation of the preloading effect using quantitative indices is performed, considering the variability of several parameters such as section geometry, amount of reinforcement, and various axial and moment preloading levels. Results are presented in the form of 3D failure surfaces and moment-curvature curves. Specific cases where the preloading effect is more pronounced are finally highlighted.
