[Seismic] discussion steel ball bearing hinge deformation limit lateral force resisting steel structures can be, can also be a reinforced concrete structure. When a lateral force resisting steel truss structure composed of pure steel, specification: Under the action of the wind, the interlayer displacement 1/400, 1/500 vertex displacement; in the earthquake, the interlayer displacement 1/250, vertex displacement 1/300. Therefore, the use of steel truss structure as anti-lateral force may cause the steel index has improved greatly, thereby increasing the cost. If you press the steel structure of the overall stiffness of the control limits 1/300 fixed hinge support, to be to work in the earthquake steel, reinforced concrete shear walls have had structural damage, such consideration is not safe enough. If by reinforced concrete shear wall 1/800 control structure limits the overall stiffness, steel beams, steel columns section due to seismic forces increase and a significant increase. When installed on the bridge of the parallel if the same skew angle of the bevel quadrilateral [seismic] ball bearing hinge, then mount along the short side of the bridge should be parallel to the long side should be parallel to the pier centerline. Skew angle along the centerline of the bridge to the pier should be consistent with an acute bearing damping hinge bearing fixed, but isolated fixed hinge bearing Under normal circumstances, this seat is not recommended, because the seat hinges The unfavorable force should be used to deform the equalization of each of [the earthquake] ball bearing hinge is appropriate. For skew bridge and curved bridge using [seismic] elastic ball bearing hinge hinge bearing fixed, should be pier, Taiwan set up on both sides of the lateral stops, or on the set between the steel plate under the anti-holder in the beam bottom plate and shift bezel and other measures. Laminated rubber bearing [earthquake] ball bearing hinge generally has a fixed end and the movable end when used on the bridge; the use of seat height, etc., the horizontal displacement of the upper structure of the two ends of the beam with a common bearing shear deformation completion of each pay half, can also be a smaller thickness of the rubber bearing as a fixed bearing. [Seismic steel ball bearing hinge] development and installation of steel as a modern "green building", because of its light weight, short construction period, fast return on investment, easy to install, good seismic performance, less environmental pollution, and other characteristics is widely used in homes, factories office, commercial, sports and exhibition buildings, and developed rapidly. And how will the steel structure to ensure the quality standards, to meet the performance situation of green construction, to achieve environmental protection, it is the construction industry each person must have a profound thought. [Seismic] ball bearing hinge Installation Notes: 1. [earthquake] is generally used ball bearing hinge bearing activities, should be used as a fixed bearing supporting the use of ordinary laminated rubber bearing. 2. [seismic] ball bearing hinge design support center by accurately place the installation must be carefully detailed. Beam bottom plate and support cushion stone (or lower plate) parallel to the top surface and smooth as possible, to ensure that the seat is fully dense paste the following; each seat with a beam should be on the same plane; avoid bearing appear eccentric pressure, uneven support and void phenomenon. Specific construction methods with the same ordinary rubber plate. 3. [seismic] ball bearing hinge after installation if a problem needs to be adjusted, the general practice is from the top end of the beam, and the bottom surface of the seat cushion support stone (lower plate) between, you can shop coat Epoxy mortar adjusted. 4. For sloping bridge, that is, when there are longitudinal beam, the specification requirements should take measures to seismic ball bearing hinge with stainless steel contact surface remains level. Such as the use made of the beam at the end embedded board corresponding to the slope of the wedge plate during longitudinal adjustment.
