Bearing steel beam intensity sliding ball joints, including the ability to bend, shear and vertical partial pressure resistance. Flexural capacity by bending stress in mechanics of materials obtained from the formula. When you press the plastic design, consider the beam to form a plastic hinge and the resulting redistribution of internal forces. Using plastic design of steel beams, compared with elastic stage designed by the beam phase, cross-sectional size can be reduced, saving steel, but generally only applicable to the static load of hot-rolled steel beams and composite beam welding, etc. section, while a combination of generous slab pieces should be more stringent than the limit, in order to avoid the plate and reduce the carrying capacity of the local buckling beam. When you press the elastic stage design Guangrun steel hinge support functions, taking the edge computing section fiber stress reaches the yield point of steel as the ultimate state. After sliding the ball bearing hinge edge fiber stress reaches the yield point, in fact, can continue to carry the load beam. As the load continues to increase, the plastic deformation along the section where the maximum bending moment on the edge of the continuous development and expansion of the central, the final form of the cross-section of the plastic hinge. Beam, the beam appears to become movable body after a certain number of plastic hinges, bending beam that reaches the limit state and damage. Slide ball bearing hinge steel girder shear capacity, in accordance with the relevant material mechanics formula. For simplicity it is generally assumed shear entirely borne by the web-sectional average calculation. Webs thicker shear strength steel is generally able to meet the design requirements. When the flexural strength of the beam by the plastic stage design, the presence of shear will accelerate the formation of plastic hinges; therefore steel hinge bearing, the maximum bending moment of shear stress on the section, there should be more stringent restrictions. Slide ball bearing hinge hinge curved arc with arc-shaped hinge has hinge and hinge arch support. Slide ball bearing hinge hinge bridge linking bridge longitudinal vertical coupling continuous hinge construction method is generally simply supported continuous beam bridge adaptation. Examples of roads and bridges in the country are also often used, it is simply supported continuous change a simple and effective method. [Slide] KQGZ seismic ball bearing hinge ball bearing steel can withstand tensile, compressive, shear (lateral) force, due to the strength and ductility of these bearings is higher than the bridge structure itself strength and ductility, therefore, the use of such support seat at random seismic force, as long as the bridge substructure itself is not destroyed, it will not fall beam, landing gear and other catastrophic consequences. Meanwhile, KQGZ spherical bearings have the ability to resist earthquake 9 degrees earthquake intensity, and it is especially suitable for high-intensity earthquake zone fortified bridge. When [slide] ball bearing hinge structure calculation diagram needs and practical calculation method is based on the schematic design is consistent when single or multi-frame structure steel hinge support national standard factory building, usually do stability analysis framework only do stability calculation frame column. This approach is used when computing framework COLUMN column length factor, through the framework of the overall stability of the analysis should be drawn so that the column stability calculation is equivalent to the framework of stability calculation. "Steel Design Code" (GB50017-2003) for single or multi-column frame given length factor using five basic assumptions, including the following: "All the pillars of the framework is stable while the loss that each column while achieving its critical load, "according to this assumption, stable framework for each column parameters, commonly used methods rod stability calculation is based on certain simplifying assumptions or typical-case scenario, designers need to confirm the structure designed to meet these It is assumed that in order to correctly apply. [Slide] [slide ball bearing hinge hinge ball bearing] KQGZ earthquake than laminated rubber bearing spherical bearings and pot bearings stiffness, deformation hinge bearing small, to ensure that large automobile and smooth high-speed train shape. KQGZ seismic bearings and spherical roller bearings and the rocking shaft bearings and other bearings compared to steel hinge pin hinge Guangrun election can not go wrong, greatly reducing the volume and height, light weight, easy installation, the cost is relatively low .
