The part of the neck should be designed, in order to prevent the sliding bearing part generated in the concrete diagram Nanjing hinge sectional under high peel stress, thereby generating a one-way split tensile steel in the general direction of the sliding bearing, and the edge portions split Rally, Rally this section must be configured reinforced to bear, the stress state of the concrete hinges. As can be seen from the figure, the larger the ratio hinge truss necking way sliding bearing, the sliding bearing to allow pressure or allowable stress, the greater the angle of the hinge when the sliding bearing hours unidirectional sliding bearing, through the hinge Concrete can be rotated on the deformed portion. And when the angle is large, the hinge portion of the concrete will crack necked, sharp increase in the pressure of concrete at this time. Sliding bearings under sustained load cracks may be due to creep deformation of concrete partially closed, sliding bearings makes eccentricity and rotational reaction force decreases bridge unidirectional sliding bearings, therefore, in determining the permissible angular and rotational torque, should discriminate based on dead load and live load conditions. Corner sliding bearings frequently occurring (eg due to temperature changes and live load, etc. to produce corner) calculation of the coefficient, the length of the short side of the hinge hinge sectional sectional length of the long side. Sliding bearing concrete hinge structure size requirements. Size of sliding bearing concrete joints shall meet the requirements of the formula. Under the action based on the use of amiable, according to the following formula to determine the lateral force be configured reinforcement. Since the torque in the eccentric rotation of the hinge's resistance to bending moment and a hinge, caused by the corresponding bending moments can be unidirectional concrete hinge bending moment M to be subjected to lateral sliding bearing in the axial direction of the hinge fully backlog, if this direction hinges withstand bending moments at the hinge side will produce the maximum stress, generally do not specifically checking. When the concrete to withstand large transverse hinge moment, you can set the intensity of the force-feeding of high crude steel hinge hinge neck in a high stress parts of the hinge strengthened.
