Lead Rubber Bearing for Building Shock Absorption Seismic Isolator Bridge Elastomeric Rubber Isolation

Product Description Lead rubber bearings are constructed by vertically inserting a lead core in the center of the rubber bearing.Lead exhibits a notably low yield stress, approximately 7MPa, and favourable fatigue properties when subjected to plastic deformations. This unique combination allows lead rubber bearings to effectively dissipate the seismic energy, with the potential to achieve the damping ratio up to 25%.This product is in compliance with the following standards:"Rubber bearings - Part 2: Elastomeric seismic-protection isolators for bridges" GB/T 20688.2-2006 "Rubber bearings - Part 3: Elastomeric seismic-protection isolators for buildings" GB/T 20688.3-2006"Rubber isolation bearings for buildings" JG/T118-2018 Detailed Photos  Product Parameters List of mechanical properties and specifications of type I lead-core building isolation rubber bearingsModelDesign bearingcapacity kNEffective diametermmSupport body height mmTotal rubber thickness mmFirst shape coefficientS1Second shape coefficient S2Horizontal performance value at 100% shear strainShear strain 250% horizontal equivalent degree kN/mmVertical stiffnesskN/mmYield force kNHorizontal equivalent stiffness kN/mmEquivalent damping ratio (Heq)%Stiffness before yield kN/mmStiffness after yield kN/mmLRB400188440015673≥15≥51.04238.840.680.79145027LRB500294450018392≥15≥51.272310.920.840.97185040LRB6004239600201110≥15≥51.582313.131.011.20220063LRB7005770700241129≥15≥51.812315.211.171.38270083LRB8007536800270148≥15≥52.052317.291.331.563100106LRB9009538900291165≥15≥52.372319.631.511.803800141LRB1000117751000334184≥15≥52.602321.711.671.984500171LRB1100142481100362202≥15≥52.972424.051.852.265000227LRB1200169561200380220≥15≥53.222426.262.022.455500264LRB1300199001300414239≥15≥53.452428.342.182.626600304LRB1400230791400461257≥15≥53.762430.552.352.867500362LRB1500264941500486276≥15≥54.052432.632.513.088400425RemarkThe design bearing capacity of the seismic isolation bearings listed in the table is calculated based on the base surface pressure of 15MPa (Category C).
