[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 fixed hinge bearing finished the latest prices, with steel truss structure for lateral force resisting steel index may cause a greater increase, thereby increasing the cost. If you press the steel structure of the overall stiffness of the control limits 1/300, when the earthquake to be participating in the work of damping steel ball bearing hinge fixed finished, reinforced concrete shear walls have had structural damage, this 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. Along the bridge should be consistent with the bearing of an acute angle to the oblique angle between the centerline of the pier, but under normal circumstances, such a stand is not recommended because of adverse bearing hinge force and 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] ball bearing hinges, should be pier, Taiwan set up on both sides of the lateral stops, or under steel and bearing steel set between anti shift bezel measures on the beam at the end. 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] ball bearing hinge mounting height Typically, the deck has a longitudinal and cross slope, even on the same mounting height of the lower bearing structure is different for each finished fixed bearing elastic hinge bearing sales calls should design elevation prevail to determine the top surface of the lower structure design height, saddle pad and saddle pad thickness stone mortar stone height. Seismic ball bearing hinge 30mm mortar thickness generally used as a benchmark. Even when the top surface of the lower structure design height cross slope, the largest earthquake trench mortar ditch ball bearing hinge hmzx, also want a small dog height H underside than bearing set as well, when the earthquake ball hinged cushion stone mortar large thickness, must be considered to set the stone cushion and support structure in the lower section of the top surface plus height and so on. [Seismic] reserved ball bearing hinge holes in the design should be drawn aside hole pattern, holes are generally reserved for standard shapes as shown. At the same time should be mainly the following questions: 1. [seismic] ball bearing hinge mounting location may lifting. 2. [seismic] ball bearing hinge completely poured into non-shrink mortar, easy operation finished perfusion fixed hinge support, and because of the size of the economy. 3. [seismic] ball bearing hinge mounting height is appropriate. Green Green Construction steel building construction, the design should be based on full consideration of green construction requirements, combined with the construction environment and conditions were optimized. Green Construction includes the following aspects: construction planning, material procurement, site construction, engineering and inspection, etc., at all stages should strengthen management and supervision to ensure the smooth progress of construction activities.
