[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. Supports multi-directional active vibration hinge system is in equilibrium when the conservative finished all types, stored in the architecture of the strain energy equal to the work done by external 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, potential energy that is always there in 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%. Steel installation] [slide ball bearing hinge mounted vertical steel columns is a major component, determine the story and the total height of the building, and therefore, the manufacturing process of steel columns must strictly enforce the acceptance criteria of existing norms. 100-meter-high steel columns are usually divided into sections 8-12 members, like the next turn in the production process material must be considered among the components of the weld shrinkage and deformation and compression deformation due to vertical loads caused. [Slide] ball bearing hinge steel columns elevation control is generally taken two ways: First, in accordance with the relative elevation of production and installation. The length of the error should not more than 3 mm multi-directional hinge bearing vibration professional design, without regard to the inter-component weld shrinkage and deformation and compression deformation caused due to the vertical load, as long as the total height of the building to reach sections of the production of steel columns the allowable deviation and steel columns integrated compression deformation sum that is considered qualified. This control is generally applicable to 12-storey building, for not very strict control storey buildings. [Slide] The second promotional ball bearing hinge fixed steel hinge bearing vibration, production and installation in accordance with the design elevation. Mainly applied to more than 12 storeys high accuracy requirements for the sum of the cumulative size of each section should be in line with the overall size of the steel columns architectural design requires. Shrinkage deformation due to the joints between steel columns and compression deformation generated due to vertical loads caused by the processing should be added to the length of the steel columns. [Slide] object ball bearing hinges, like a bridge, in the horizontal direction elongated structure, the main issue is the effect of wind direction from the cross bridge for bridge superstructure it as transverse to the role of horizontal wind loads to consider. For bearing purposes must have a role in the bridge superstructure to ensure that the seam load level force generated function reliably transmitted to the lower portion of the bridge structure.
