Support forces around forever deformed by Globe, can release moment, turning moment only concerned with the bearing angle is independent of the size of the spherical radius of the steel liner plate, so a small rotational torque spherical bearing, spherical ball joint bearing current The angle can be used as 0.06rad and above, for large angle of bridge bearings. While rotating the pot bearing pot by deforming the rubber sheet need to adapt the beam angle, the ball bearing due to the rotation of the hinge the impact deformation of the rubber rubber plate diameter, thickness and hardness of the seat is rotated by means that, with the significant changes in the change holder corner, the ball bearing hinge moment is the response, and the thickness of the rubber sheet with certain restrictions, under the conditions of the thickness of the rubber sheet seismic restricted unidirectional sliding bearing steel ball joints, pot bearing design angle is generally less than 0.02rad, so the pot bearing rotation range of adaptation and flexibility yuan excluding spherical bearing, while the ball bearing hinge to rotate each performance has been, and is more suitable for a wide curved bridge and the bridge occasions. Spherical bearings do not use rubber bearings under pressure so there is no reason to affect the British rubber aging 碧昂 ball bearing hinge rotation function problems, more suitable for use on low-temperature region bridge engineering. Spherical bearings do not use rubber pressure in accordance with national standards for the performance of spherical bearings do a bit of attention to several aspects of the basic requirements. Lower ball bearing hinge basic performance requirements of the role and then vertical design bearing capacity, ball bearing hinge vertical compressive deformation had to be greater than 1% of the total height of seat. In determining the need for lifting the total weight of the beam to analyze the forces at each pivot point should be based on their specific situation, or have conditions permit is based on a one-way movable seismic design and construction drawings to not stress analysis hinged steel ball bearings, determine the approximate distribution of the load, according to what the distributed computing forward-top setting in the theoretical load hydraulic jack weighing analysis approach. But generally should be adopted when the total amount of the bridge-girder, the ball bearing hinge construction according to the Champions League empirical data, subjected to vertical loads from steel reinforced with stiffening rubber bearing stress state shown. Upper and lower ball joints stiffened steel plate bearing bound rubber ball joints swelled unidirectional seismic displacement steel bearing, ball bearing hinge between the two contacts to generate shear. According tension stiffening steel produced. Tension stiffening steel produced increases with the rubber sheet thickening estimated according to the following empirical formula; the total weight of the beam, construction bridge span in the sum of all the upper structure of gravity; constrained seismic coefficient hinged steel ball bearing, ball bearing hinges According to theoretical calculations were constrained circumstances or determined by tests, bridges dynamic load, dynamic load coefficient. Taking into account the overall construction of a simply supported beam, vehicle dynamic load attenuation along the transverse direction, and each pivot point analysis supported bridge force be estimated according to the following.
