Experimental Investigation on Rehabilitation of Corroded RC Columns with BSP and HPFL under Combined Loadings
Publication: Journal of Structural Engineering
Volume 146, Issue 8
Abstract
This research focuses on evaluating the seismic properties of corrosion-damaged RC columns strengthened by bonded steel plate (BSP) and high-performance ferrocement laminate (HPFL). The mechanical properties are experimentally investigated based on various combined loading cases. A total of nine square RC columns with identical structural properties are produced, and five of them are corroded and poststrengthened with BSP and HPFL. The effects of the combined loadings, bearing capacity, failure mode, skeleton curves, hysteretic curves, ductility, stiffness degradation, energy dissipation, and plastic hinge characteristics are analyzed. In particular, a new method for calculating the skeleton curves under different failures modes is proposed and agrees well with the experimental results by comparison.
