After the test, the following conclusions by these two types of hinge to withstand pulses and pulse load combined with the design of the corner box ah finished multi-directional slide hinge bearing, the rotation test was made after pressing the shear test, which is similar to the case of the slide bearing hinges can be seen in the concrete surface manholes along the crack spalling, and in the steel hinges do not see this phenomenon proves steel played a role. Hinge sliding bearing is free to rotate in any direction. Sliding bearings and "existing hinge different" because of the neck is not easy even concrete, so its function is less than to the good of finished steel unidirectional sliding hinge bearings, indicating that under pulsed load, steel hinge hinge for stable than concrete, so the concrete pay attention to different directions hinge vibration compacting. According to the test of experience in Germany, hinge reinforcement shall be arranged in accordance with the test and the test results photoelastic model full-scale concrete hinges, hinge on the concrete proposal is designed primarily through the midpoint of the hinge reinforcement arranged to account for 40% of steel, slide The remaining 60% of the bearing steel is arranged along the longitudinal direction. Since the hinge pin hinge corner sliding resistance grid finished, the torque generated by the angular rotation of the anti-torque hinge at the center of the west, as the vertical force on the hinge. Under the action of the force N in the hinge will produce a concrete crack tension. Sliding bearing friction coefficient is 0.03. Sliding bearing horizontal shear vertical bearing capacity of more than 20% of vertical bearing capacity of sliding bearings for 1000-60000kn, divided into 25 specifications washing. Adaptation sliding bearing sliding bearing temperature -40-70 maximum allowable angle is 0.03rad, the main features of the seismic structure of spherical bearings can be attributed to having a universal rotation, universal bearing, the upper structure of the bridge to meet the various loads , generated by a reaction force transmitted rotational displacement requirements. Seismic spherical steel bearing under pressure, shear, due to the strength and performance of such bearings is higher than the strength and toughness of the structure itself. Use the holder at random seismic force, as long as the structure itself does not destroy the bridge down, it will not fall beams and other consequences of disaster.
