The　importance　of　reinforced　concrete　column　components　as　important　load-bearing　components　in　building　structures　is　self-evident.　Based　on　the　research　objective　of　evaluating　the　performance　of　cumulative　damage　components,　this　article　conducted　experimental　research　on　cumulative　damage　and　residual　bearing　capacity　of　reinforced　concrete　columns.　Four　reinforced　concrete　compression　and　bending　column　components　with　a　cross-sectional　size　of　300　mm　were　analyzed　for　their　mechanical　performance　degradation　after　gradually　accumulating　damage　during　constant　amplitude　hysteresis　loading,　as　well　as　the　residual　bearing　mechanical　performance　of　the　damaged　components.　©　2024　selection　and　editorial　matter,　Seyed　Mohammadreza　Ghadiri　and　Yan　Zhuge:　individual　chapters,　the　contributors.　All　rights　reserved.
