How does seismic isolation work? 2Structural Bearing Assemblies Isolation Bearing Systems Seismic Isolation reduces substructure demand whereas traditional design tries to resist it. Increasing Period of Vibration Acceleration High Demand Low Demand 30. Seismic isolation = Safer bridges 2Structural Bearing Assemblies Isolation Bearing Systems Use of R-Factors > 1.0 inherently accept that damage will occur under the design level event This leaves little to resist subsequent earthquakes or larger earthquakes than assumed during design The efficiency of seismic isolation improves as the earthquake acceleration level increases 31. Seismic isolation = Safer bridges 2Structural Bearing Assemblies Isolation Bearing Systems Since substructures remain elastic in isolated structures, significant capacity remains beyond the design-level event 0.000 0.100 0.200 0.300 0.400 0.500 0.600 0.700 0.800 0.0 0.5 1.0 1.5 2.0 2.5 3.0 Acceleration(g) Effective Period (sec) 0.1g Soil Type II 0.2g Soil Type II 0.3g Soil Type II Demand is less than 0.2g greater at long periods Demand is 0.5g greater at short periods 32. Load Redistribution 2Structural Bearing Assemblies Isolation Bearing Systems In addition to reducing seismic forces by shifting the period of vibration and adding damping Seismic Isolation bearings permit redistribution of service and seismic lateral loads to substructures best able to resist them away from vulnerable substructures away from hard-to retrofit locations to maintain historic appearance 33. 2Structural Bearing Assemblies Versiflex HLMR Spherical Bearing Assemblies AASHTO maximum pressure of 5500psi (37.9MPa) on PTFE High rotation capabilities: >0.03 radians Project specific design Concave Plate with Woven PTFE Stainless Steel Convex Plate 34.
