Bridge bearing

详情

GPZ Series Pot Bearings are designed in accordance with BS ***0 - British Standard - Section 9.1 and 9.2, EN ***7 - European Norm, AASHTO - American Association of State Highway and Transport officials. Its main properties parameters are listed as follows:
 
1.     The design vertical load capacity of a bearing covers a range of 0.8MN~*0MN, which is divided into *3 classes.
 
2.     Vertical design rotation of a bearing is 0.*2 rad (approximately 1.*5o ) and it is applicable to horizontal rotation of any sizes.
 
3.     The horizontal load capacity of a fixed bearing (FX) in all directions and guided sliding bearing (SGL) in limited direction reaches *0% of vertical load capacity of the bearing.
 
4.     Designed values of friction coefficient of bearings:                                                                 
 
a.         Normal temperature (**5 oC ~ **0 oC) : u <= 0.*3
 
b.        Low temperature (**0 oC ~ **5 oC) : u <= 0.*6
 
5.     Special design may be adopted if the displacement and vertical/horizontal load capacity exceed relevant standard values.
