Dynamic behavior and damage assessment of RC columns subjected to lateral soft impact

•Performance and damage behavior of reinforced concrete (RC) columns under lateral soft impact were numerically investigated.•A section damage factor was defined to illustrate the damage evolution of impacted columns.•Criteria for both flexural damage and shear damage of columns were proposed based...
