Seismic Fragility Assessment of an Isolated Multipylon Cable-Stayed Bridge Using Shaking Table Tests

Table 3

Damage scheme for the correlation of the visual damage to the damage state.

Components	Damage typology	Damage state 1 (DS1)	Damage state 2 (DS2)
		Slight damage	Moderate damage
Cable	—	N/A	Broken anchor
Pylon	Drift	Drift larger than 0.3%	Drift larger than 1.5%
Pier	Crack or steel yield	Minor crack of concrete	Pier acceleration larger than 1.2 (g)
Bearing	Displacement	N/A	Peak displacement larger than 1 cm or uplift of top slab
Deck	Residual displacement	N/A	Residual displacement larger than 0.7 cm

Note. N/A means that this type of damage state is not defined.
