Experimental and Numerical Study on the Earthquake Damage of Spherical Bearings for Chinese High-Speed Railway Bridge

Table 9

Comparison of maximum displacement of typical bearings (under 0.45 g) for the experimental test and FE model (mm).

Earthquake direction	Bearing number	Test (mm)	FE model (mm)	Difference (%)
x direction (xp)	2 #	1.03	0.83	19.42
	4 #	2.89	2.10	27.34
	6 #	0.12	0.08	33.33
	8 #	1.71	1.36	20.47
y direction (yp)	2 #	0.63	0.56	11.11
	4 #	1.68	1.45	13.69
	6 #	0.09	0.06	33.33
	8 #	1.34	1.15	14.18

Note. difference = (test result–FE model result)/test result  × 100%.
