Slide the plastic steel ball bearing hinges, good toughness. Good plasticity, suggesting that the material to resist static tensile load ability ball bearing variety, good toughness, indicating strong resistance to dynamic load capacity material, plastic steel, good toughness, steel construction both showed resistance large anti-static load can put a large dynamic loads. Based on the characteristics of the seismic performance of steel buildings are more superior. Slide ball bearing hinges passed the test the following conclusions: These two types of hinges withstand pulse loads and pulse combined with the design of the corner load supply ball bearings offer, according to the rotation test before making a shear test, their situation with similar. Hinge can be seen in the concrete along the crack surface flaking mortar, and in steel hinges do not see this phenomenon, proved steel played a role. Hinges free to rotate in any direction, and "linear hinge" is different, since the hinge portion is not easy even concrete, steel plate so that its function less well. This shows that the pulse loads, steel hinge hinge more stable than concrete, so the concrete joints in different directions to note vibrating compaction. According to the German experience, reinforced hinges shall be arranged in accordance with the test results and photoelastic model full-scale concrete hinges, hinges on the concrete design of the main remaining recommendations are reinforced through the midpoint of the hinge to account for 40% of the arrangement of reinforcement, the 60% reinforced longitudinally arranged. Slide ball bearing hinge hinge concrete design calculations and requires the hinge rotation resistance generated by rotating counter moment M at the center of the eccentric hinge moment e = M / N, N is the vertical force hinges on the role of force in N next, in the hinge will produce a concrete crack tension Z1 (in the Y-axis direction), then to come to bear tensile Z1 by arranging reinforcement. Meanwhile ball bearings, hinges on the end face of the concrete should be set necking part to prevent the stripped portion of the concrete produced under high stress; thus the Z-axis direction will produce splitting tensile Z2 and Z3 edges split Rally This section should also be configured to pull reinforced to bear. [Slide ball bearing hinge Energy Act] energy method is an approximate method for solving stability capacity, by the principle of conservation of energy and potential energy in principle to solve the critical load values. 1) the principle of conservation of energy to solve the critical load. When the system is in equilibrium conservative, stored in the structure of the system is equal to the work done by the strain energy forces, namely the principle of conservation of energy. Energy relationship for the critical state: ΔU = ΔW Where ΔU --- refers to the strain increment energy; ΔW --- refers to the incremental external success. [Slide ball bearing hinge] by the principle of conservation of energy equilibrium equations can be established. 2) the value of the potential energy in principle to solve the critical load. Principle of stationary potential energy means: structure by external force, and when there are small changes in the displacement of the total potential energy seismic ball bearing weight is how much potential there is in the total value, the structure is in equilibrium. Expression is: dΠ = dU-dW = 0 where dU --- means that the strain energy within the structural changes induced by virtual displacement, it is always positive; dW --- refers to the force in the virtual displacement as function. [Slide] ball bearing hinge design technical parameters 1) the design of vertical bearing capacity of 0.8-80MN 2) 30% level of design capacity was greater than the design vertical bearing capacity. 3) design of vertical uplift force is greater than the vertical bearing capacity 50% 4) Design Corner bit 0.02rad. 5) horizontal displacement of plus or minus sign 15mm-- 500mm 6) Design sliding friction coefficient of less than 0.02 7) designed damping ratio of 15% - 25%.
