The range of damage index for different damage states for reinforced concrete structure [50].

Damage stateDescription of the damage stateDamage index

Essentially no damageThe load-bearing components are intact, and some non-load-bearing components are slightly damaged0.00∼0.10
Slight damageIndividual load-bearing components have slight residual deformation, and individual non-load-bearing components are obviously damaged0.10∼0.20
Moderate damageMost of the load-bearing components have slight residual deformation, and some of them are obvious0.20∼0.50
Heavy damageMost of the load-bearing components are seriously damaged or partially collapsed0.50∼0.75
CollapseMost of the load-bearing components are collapsed0.75∼1.00
