Bearing model parameters.

Model number	Bearing type	Total rubber thickness (m)	Number of rubber layers	Shape coefficient
P-1	GJZ 500 × 550 × 60	0.04	5	16.38
P-2	GJZ 500 × 550 × 80	0.05	5	13.10
P-3	GJZ 500 × 550 × 80	0.06	5	10.91
P-4	GJZ 500 × 550 × 95	0.075	5	8.73

Notes: the design of the bearing shape coefficient meets the requirements of the “Specification for the Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts” (JTG3362-2018) [46].
