Bond strength and confinement in reinforced concrete

The strength assessment of existing reinforced concrete structures is challenging when deterioration and detailing deficiencies are present. anchorage the internal steel reinforcement can be critical under particular confinement conditions external pressure, cover transverse reinforcement. interaction between different contributions their effects on bond were investigated with a novel experimental set-up that removed parasitic support pressure. With significant varying cover, maximum strengths obtained for intermediate cover-to-diameter ratios. contribution depended occurrence splitting cracks. These findings lead to improved maintenance strategies.
