Test parameters of bearings.

Serial number	Bearing type	Total rubber thickness (m)	Shape coefficient	Vertical load (MPa)
B1	GJZ 500 × 550 × 78	0.048	16.38	4
B2	GJZ 500 × 550 × 78	0.048	16.38	6
B3	GJZ 500 × 550 × 78	0.048	16.38	8
B4	GJZ 500 × 550 × 78	0.048	16.38	10

Notes: (1) the bearing design should meet the requirements of the “Series of Elastomeric Pad Bearings for Highway Bridges” (JT/T663-2006) [45]; (2) the vertical compressive stresses of the bearings should meet the requirements of the “Specifications for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts” (JTG3362-2018) [46].
