SIMPLIFIED APPROACH TO ASSESS  LEVEE SEISMIC VULNERABILITY  Presentation for SAME Conference October 2009, Sacramento, California Scott Shewbridge, Jerry Wu [1] , Sujan Punyamurthula, Juan Vargas [2] , Steve Mahnke, and Mike Inamine [3] [1]   URS Corporation, 1333 Broadway, Suite 800, Oakland, CA 94612,  [email_address]  and Jerry_Wu@urscorp.com [2]   URS Corporation, 2870 Gateway Oaks Drive, Suite 150, Sacramento, CA,  [email_address]  and  [email_address]   [3]   Department of Water Resources, Division of Flood Management, 2825 Watt Avenue #100, Sacramento, CA 95821  [email_address]   and    [email_address]
Assessment of Seismic Vulnerability  ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Newmark Approach Force = Mass * Acceleration Relative Acceleration – a = a y  - a f Integrate once – Relative Velocity = at  Integrate twice- Relative Displacement = ½ at 2 Relative  Displacement

Estimates of Peak Ground Acceleration (PGA)
Assessment of Seismic Vulnerability  ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Example Finite Element Model Inputs & Results Calculated Peak Horizontal Acceleration 1979 Imperial Valley Earthquake,  USGS 286 Station, 135-Degree Component Scaled to 0.5g Input Motion - - - 1100 125 Elastic Base Vucetic & Dobry, PI=30 0.45 - 900 125 Pleistocene (CL) Seed-Idriss Sand (mean) 0.35 50 - 125 Holocene (Medium Dense Sand) Seed-Idriss Sand (mean) 0.35 25 - 115 Levee Fill (Silt) G/Gmax and Damping Curves Poisson’s Ratio K 2 max Vs (ft/s) Unit Weight (pcf) Material
Estimate of Cyclic Stress Ratio (CSR)
Assessment of Seismic Vulnerability  ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
How do we evaluate K y ? Limit Equilibrium – Increase seismic coefficient until FS = 1 Infinite Slope Multi-block Wedge
Use Slope Stability Program UTEXAS4 is the only currently authorized computer program
Interpolate to Evaluate K y ,[object Object],[object Object],[object Object],K y
Evaluate Liquefaction Triggering Using  Seed et al (2004)*  Set Duration Weighting Factor = 1 All Events
Estimate Liquefied Soil Strengths using  Seed and Harder (1990)
Use Undrained Residual Strength to Assess Post-Liquefaction Triggering K y Su = 250psf

Estimate of Site Response and  2-Dimensional Effects (K max )
Asymmetry/Stiffness Asymmetry may be important and can be considered. “ Stiffer” Asymmetric “ Stockton” “ Medium” Less Symmetric “ Marysville” “ Softer” Symmetric “ Sacramento”
Choose Model Based on Stiffness
Assessment of Seismic Vulnerability  ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Example Newmark Calculation  Results
West Sacramento  Stockton  Marysville All scaled to be compared directly with Makdisi-Seed (1978) Interpretation of Results Displacement = f(K y /K max ? Block Type/Depth? Magnitude/Duration? Scaled PGA?) ,[object Object]
Displacement = (K y /K max )?  YES  K y /K max  has an impact on K y /K max  estimates of displacement
Displacement = f(Block Type / Depth)?  NO  Scaled PGA –  0.05  0.2  0.5 M6.5 M7.25 M8 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Magnitude Block Type and Depth have no apparent impact on K y /K max  estimates of displacement
Displacement = f(Magnitude/Duration)? Yes for K y /K max  < 0.4  Scaled PGA –  0.05  0.2  0.5 M6.5 M7.25 M8 Magnitude Magnitude / Duration has an apparent impact on K y /K max estimates of displacement
Displacement = f(Scaled Input PGA)? Yes, but…  Scaled PGA –  0.05  0.2  0.5 M6.5 M7.25 M8 Magnitude Concern that Scaled Input PGA apparent impact on K y /K max estimates of displacement is only a numerical result Possible resolution –  Spectral Matching and  Arias Intensity screening
Use Model for Scaled Input Motion = 0.2g for Vulnerability Assessment  Scaled PGA –  0.05  0.2  0.5 M6.5 M7.25 M8 Magnitude 0.2g scaled PGA model results are believed to provide a reasonable expected relationship for the study areas
Summary – Levee Deformation  Evaluation Charts PGA = f(Return Period) CSR = f(PGA) K max  = f(PGA, block depth, model stiffness) Displacement = f(K y /K max , Magnitude)
Freeboard Loss Assessment ,[object Object],[object Object]
Vulnerability Assessment Compromised None Yes Unlimited (flow slide condition) Likely Compromised None Likely if existing 3’ to 10’ Possibly Compromised >1’ Possibly 1’ to 3’ Probably Uncompromised >1’ No <1’ POST SEISMIC FLOOD PROTECTION ABILITY REMAINING FREEBOARD  FOR POST SEISMIC EVALUATION (2-YEAR FLOOD WATER SURFACE ELEVATION?) SIGNIFICANT DAMAGE TO INTERNAL STRUCTURES (E.G. CUTOFF WALLS AMOUNT OF DEFORMATION

  • 1. SIMPLIFIED APPROACH TO ASSESS LEVEE SEISMIC VULNERABILITY Presentation for SAME Conference October 2009, Sacramento, California Scott Shewbridge, Jerry Wu [1] , Sujan Punyamurthula, Juan Vargas [2] , Steve Mahnke, and Mike Inamine [3] [1] URS Corporation, 1333 Broadway, Suite 800, Oakland, CA 94612, [email_address] and Jerry_Wu@urscorp.com [2] URS Corporation, 2870 Gateway Oaks Drive, Suite 150, Sacramento, CA, [email_address] and [email_address] [3] Department of Water Resources, Division of Flood Management, 2825 Watt Avenue #100, Sacramento, CA 95821 [email_address] and [email_address]
  • 2.
  • 3. Newmark Approach Force = Mass * Acceleration Relative Acceleration – a = a y - a f Integrate once – Relative Velocity = at Integrate twice- Relative Displacement = ½ at 2 Relative Displacement
  • 4.
  • 5. Estimates of Peak Ground Acceleration (PGA)
  • 6.
  • 7. Example Finite Element Model Inputs & Results Calculated Peak Horizontal Acceleration 1979 Imperial Valley Earthquake, USGS 286 Station, 135-Degree Component Scaled to 0.5g Input Motion - - - 1100 125 Elastic Base Vucetic & Dobry, PI=30 0.45 - 900 125 Pleistocene (CL) Seed-Idriss Sand (mean) 0.35 50 - 125 Holocene (Medium Dense Sand) Seed-Idriss Sand (mean) 0.35 25 - 115 Levee Fill (Silt) G/Gmax and Damping Curves Poisson’s Ratio K 2 max Vs (ft/s) Unit Weight (pcf) Material
  • 8. Estimate of Cyclic Stress Ratio (CSR)
  • 9.
  • 10. How do we evaluate K y ? Limit Equilibrium – Increase seismic coefficient until FS = 1 Infinite Slope Multi-block Wedge
  • 11. Use Slope Stability Program UTEXAS4 is the only currently authorized computer program
  • 12.
  • 13. Evaluate Liquefaction Triggering Using Seed et al (2004)* Set Duration Weighting Factor = 1 All Events
  • 14. Estimate Liquefied Soil Strengths using Seed and Harder (1990)
  • 15. Use Undrained Residual Strength to Assess Post-Liquefaction Triggering K y Su = 250psf
  • 16.
  • 17.
  • 18. Estimate of Site Response and 2-Dimensional Effects (K max )
  • 19. Asymmetry/Stiffness Asymmetry may be important and can be considered. “ Stiffer” Asymmetric “ Stockton” “ Medium” Less Symmetric “ Marysville” “ Softer” Symmetric “ Sacramento”
  • 20. Choose Model Based on Stiffness
  • 21.
  • 23.
  • 24. Displacement = (K y /K max )? YES K y /K max has an impact on K y /K max estimates of displacement
  • 25.
  • 26. Displacement = f(Magnitude/Duration)? Yes for K y /K max < 0.4 Scaled PGA – 0.05 0.2 0.5 M6.5 M7.25 M8 Magnitude Magnitude / Duration has an apparent impact on K y /K max estimates of displacement
  • 27. Displacement = f(Scaled Input PGA)? Yes, but… Scaled PGA – 0.05 0.2 0.5 M6.5 M7.25 M8 Magnitude Concern that Scaled Input PGA apparent impact on K y /K max estimates of displacement is only a numerical result Possible resolution – Spectral Matching and Arias Intensity screening
  • 28. Use Model for Scaled Input Motion = 0.2g for Vulnerability Assessment Scaled PGA – 0.05 0.2 0.5 M6.5 M7.25 M8 Magnitude 0.2g scaled PGA model results are believed to provide a reasonable expected relationship for the study areas
  • 29. Summary – Levee Deformation Evaluation Charts PGA = f(Return Period) CSR = f(PGA) K max = f(PGA, block depth, model stiffness) Displacement = f(K y /K max , Magnitude)
  • 30.
  • 31. Vulnerability Assessment Compromised None Yes Unlimited (flow slide condition) Likely Compromised None Likely if existing 3’ to 10’ Possibly Compromised >1’ Possibly 1’ to 3’ Probably Uncompromised >1’ No <1’ POST SEISMIC FLOOD PROTECTION ABILITY REMAINING FREEBOARD FOR POST SEISMIC EVALUATION (2-YEAR FLOOD WATER SURFACE ELEVATION?)
