Capacity Assessment of Existing RC Columns
Existing reinforced concrete (RC) members, designed in accordance with obsolete codes, are often characterized by high stirrup spacing. The collapse mechanisms generated by high stirrup spacing are typically related to the buckling of longitudinal reinforcement and can be accentuated when corrosion takes place.

Seismic Behaviour of Corroded RC Column
Corrosion of reinforcing steel in concrete structures is a widespread issue that significantly impacts the structural integrity and performance of these elements, particularly under seismic loading. This study investigates the seismic behavior of corroded reinforced concrete (RC) columns .The main objective is to assess the effects of corrosion-induced
