[Slide] carrying steel ball bearing hinge design should be in ensuring structural safety, meet the requirements of the premise, to make structural steel the amount most provinces, the lowest cost. So the ball bearing hinges, how to choose a reasonable cross-section of the rod to roll in to meet the strength, stiffness and stability requirements of the premise ball bearing hinge exceeded the national standard, the minimum amount of steel ultimate goal is to optimize the design. [Slide] ball bearing hinge section when performing optimization, we must consider the following points :( 1) component strength, stability checking. Optimized sectional dimensions must meet the requirements of strength, stability, structure design to meet security requirements. (2) stiffness requirements. Sectional dimensions in optimizing the overall stiffness of the structure must meet the relevant requirements specification deformation control finished full range two-way ball bearing hinge, ie, the maximum deflection of the beam, the maximum horizontal displacement of capitals, crane rails at the top of the maximum horizontal displacement of the column must meet the specification limits for deformation. (3) construction requirements. Optimized sectional dimensions must meet the requirements of the relevant norms of construction and use requirements. Such as column flange thickness ratio, the web thickness ratio of cross-sectional dimensions, etc. must satisfy the relevant requirements. (4) production, installation control conditions. Optimization of the member section size must meet conventional production, installation requirements. [Slide] spherical ball bearing hinge tension and compression tension and compression spherical bearing seat (QZ seat tension and compression), the product around the world similar products, mainly through the center of the tension in the seat bolts, the upper and lower seat board connected whole, so that can withstand the pressure bearing structure construction can withstand a certain tension. [Slide] ball bearing hinge tension and compression rectangular laminated rubber bearing laminated rubber bearings in the upper and lower set of steel gusset structure so as to achieve the bear pulling force can, by Hebei Hengshui Guangrun Engineering Rubber Co., tension and compression rectangular plate Rubber branch is one of them. [Slide] ball bearing hinge unidirectional activity coefficient of sliding friction bearing design: non Earthquakes finished grease lubricated bearings offer two-way seismic ball joints, room type bearing design minimum friction coefficient value of 0.03; cold-branched Block design friction coefficient value of 0.06 minimum. conceptual design of the steel structure stability [slide] ball bearing hinge strength and stability of the difference between the maximum stress intensity refers to the structure or a single member state of stable equilibrium caused by the load (or internal forces) exceeds the ultimate strength of materials, 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 column, lateral deflection when the instability 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 time, the instability is the destruction of the pillars the main reason. In addition,] [slide ball bearing hinge edge of the rubber damping ring opening set after the earthquake affected by the level of loading force of extrusion steel pots, 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.
