Behavior and Efficiency of Corrosion Damaged Half-bottle Shaped Struts
Abstract This study investigated the behaviors, strut efficiency factor, and the effective width of corrosion-damaged half-bottle shaped struts. Six half-bottle shaped struts were subjected to varying aimed corrosion levels (0%, 3%, 6%) with different reinforcement mat rotation angles (0°, 45°), and their behaviors and typical failure modes ascertained. Strut efficiency factors and effective width were calculated and evaluated. Average strength of 6% corroded struts was 30% less than those of uncorroded struts. The AASHTO LRFD 2013 process predicted strut efficiency factor of corrosion damaged struts better than ACI 318–14 and EN 1992. Strut effective width also reduced with increasing reinforcement corrosion. The theoretical effective width near the load bearing plate was underestimated compared to the measured effective width, while the effective width far from the load bearing plate was overestimated.
