Seismic damage correlation coefficient of bridge components.

Destruction types	Bearing	Pier	Girder displacement	Abutment	Foundation	Unseating	Superstructure	Collision
Bearing	1	0.907	0.958	0.933	0.761	0.972	−0.264	0.932
Pier	0.907	1	0.989	0.998	0.941	0.855	−0.186	0.889
Girder displacement	0.958	0.989	1	0.995	0.909	0.924	−0.175	0.938
Abutment	0.933	0.998	0.995	1	0.920	0.880	−0.216	0.901
Foundation	0.761	0.941	0.909	0.920	1	0.760	0.119	0.859
Unseating	0.972	0.855	0.924	0.880	0.760	1	−0.046	0.979
Superstructure	−0.264	−0.186	−0.175	−0.216	0.119	−0.046	1	0.098
Collision	0.932	0.889	0.938	0.901	0.859	0.979	0.098	1

Note. Collision mainly refers to the collision between adjacent main girders of the RC girder bridge during earthquakes.
