Sliding bearing according to local compression circular cylindrical area with the maximum stress on the contact surface of the flat plate to determine the allowable force, Hertz contact stress formula, the cast of the elastic modulus. Up and down the length of the contact line two-point board. Radius circular surface, when a preliminary estimate available. Only allow local compression stress steel contact. Checking before sliding bearing shear pin degrees. Sliding bearing friction braking resistance or load pin D allowable shear stress. There are various forms of sliding bearings, in addition to the form of the main bearing to do a special presentation, slide bearings in addition some improvements in the form of special-purpose stand and on the basis of the above form and new features are merged into a bridge abutment other forms of support. Neck section sliding bearing hinge generally be made of concrete circular or octagonal, neck diameter is smaller than the root of the concrete hinge Nanjing map size, splitting tensile stress usually made of concrete reinforced to withstand a two-way sliding bolt ball bearing hinge The minimum height of the bolt ribs arranged about 0.7d, sliding bearing spiral bar area can be estimated, the axial force acting on the hinge and screw diameter bars, bridge structure design is often due to various factors, such as high strength bridge site slide ball bearing hinge, bridge span may be completely unbalanced arranged sliding ball joint bearing, causing some tension and compression support at the problem cropped up again. That pressure is tension grid sliding ball joint bearing, based on past experience in the design, the proportion of the sliding bearing bridge across the edge of the hungry should be controlled at 0.52-0.62, when using the side span span of 0.5 or more hours . To set the general tension in the transition pier bearing, not only that bridge, sliding bearing some large venues between roof trusses supporting column will appear the same situation. In order to overcome the pull force structure using some balance weights approach, but multi-use set of skills under pressure and can withstand the tension mount form to apply, therefore, bearing structure in the form known as the twelfth generation appeared in works to produce sales.
