Seismic Vulnerability Evaluation of a Three-Span Continuous Beam Railway Bridge

Table 5

Damage states and parameters of bearings.

Bearing type	Slight damage		Moderate damage		Severe damage		Complete destruction
	Median		Median		Median		Median
LQZ	150 mm	0.246	225 mm	0.246	375 mm	0.472	750 mm	0.472
KZQZ	100 mm	0.246	150 mm	0.246	250 mm	0.472	500 mm	0.472

Note. LQZ represented movable spherical steel bearing, whereas KZQZ represented movable hyperboloid spherical seismic isolated bearing.
