[Slide] ball bearing hinge unidirectional activity coefficient of sliding friction bearing design: earthquake plus non-grease lubricated, room type bearing design minimum friction coefficient value of 0.03; cold-type bearing design minimum value of the coefficient of friction 0.06 The concept of stability design of steel ball sliding hinge support [] the strength and stability of the difference between the maximum stress intensity is defined as the limit (or internal forces) structure or a single member state of stable equilibrium caused by the load exceeds building materials strength, so it is a stress problem. Ultimate strength values ??due to characteristics of the material varies, the steel is taking its yield point. The main is to find stability between the external load and the internal resistance of the structure unstable equilibrium state, that began the rapid growth of the deformation and trying to avoid the need to enter the state, so it is a variant of the problem. Such as axial compression standard pipe truss bearing Zhuguo quality first, when the instability of the lateral deflection of the column so that columns add significant additional moment, and thus undermine the pillars of the load can be much lower than its axial compressive strength, this when instability is the main reason for the destruction of the pillars. In addition, Zhejiang truss bearing sales of the first, in [slide] ball bearing hinge rubber damping ring set on the edge of the mouth of the steel basin level after the earthquake loads by force of compressional deformation, so that the seismic energy released. In addition to having the energy dissipation effect, since the intermediate bearing plate or bowl bearing steel plug into the lower basin, the phenomenon is not generated when an earthquake off the beam, after the earthquake on the bridge pier (Taiwan) is not the force will have too much influence. [Slide] ball bearing hinge intelligent bridge bearings made in foreign countries with the same performance and alternative dynamometer bearing holder, such holder is a fundamental characteristic that can be used to collect information on "smart" bridge bearings. [Slide] ball bearing hinge bearing failure or serious injury and the risk of stress arising therefrom is a common cause of damage to the bridge, which is a bridge maintenance and inspection requirements for content. Intelligent monitoring and diagnostics bridge bearings can transfer to the support of the live load and dead load through the bridge structure system. Intelligent Bridge bearings are based on if the stiffness of the bridge structural members due to breakage, impact or other reasons obvious change, is likely to be assigned to the load bearing on the principles will change, that is, [slide ball hinged Block] intelligent bridge bearings can detect the extent of damage poly bridge. [Slide] ball bearing hinge design: construction details provide a basis for the preparation of factory truss bearing all types, depth and content to be complete, but no redundancy in the design drawings, design basis, load data (including earthquake), technical data, material selection and material requirements, design requirements (including manufacturing and installation, inspection of weld quality grade, painting and transportation, etc.), structural arrangement, the member section and the main node selection and other structures should be constructed clarity, in order to facilitate the smooth preparation of construction details, and can correctly reflect the intent of the design. The main material should list representation. July 2, 1993 to 18, after the closure of the main beam Tendons tensioning process end fulcrum reaction force changes were tested, proven bearing structure is in good working condition. [Slide] and ball bearing hinge fulcrum reaction force change process also changes with the calculated reaction force to the agreement process, indicating a stable pot rubber bearing dynamometer performance, played a detection prestressed girder beam from the second action reaction force change also reflects the construction to meet the design requirements, to achieve the desired purpose. The bridge end fulcrum reaction force measured value and the calculated value is very close.
