Reinforcement corrosion in rc hollow piers: destructive and non-destructive tests

HIGHLIGHTS

SUMMARY

    In Italy and in many other countries, a commonly used construction technique for piers is the hollow reinforced concrete (RC) pier that provides, at the same time, strength and reduced mass compared to solid sections. Few results are available for corrosion of RC bridge piers with hollow cross sections: in particular, the corrosion of steel rebars determined a significant reduction in the lateral strength, secant stiffness and energy loss per cycle of the piers, both experimentally and numerically. This study investigated two 1:3 scaled hollow piers after corrosion, similar to previously tested non . . .
