Cyclic loading tests of RC columns strengthened with high ductile fiber reinforced concrete jacket

摘要: Abstract High ductile fiber reinforced concrete (HDC) is characterized by its tensile strain-hardening behavior and high compressive strain ability. This paper investigates the seismic performance of (RC) columns strengthened with HDC jacket, eight RC were designed six them jacket or bar mesh mortar (BMRM) jacket. The influence jacketing schemes axial load ratio on failure modes, hysteresis loops, skeleton curves, deformation capacity energy dissipation analyzed respectively. experimental results from lateral cyclic loading tests specimens show that mode could be changed brittle to under confinement effect jackets. without was certified more effective than BMRM in improving plastic original columns. best strengthening scheme, jacketed which exhibited tremendously enhancement drift developing hinges column foot even when ratio.
