Soil Curves

In the Visual-Q4M it is possible to perform two types of dynamic analysis:

  • Elastic linear analysis: the properties Shear Modulus and Damping do not change during the calculation and you can make only a single run. For perform this type on analysis do not select none curve for the lithologies.
  • Equivalent linear analysis: the properties of Shear Modulus and Damping change during the calculation and you can make more run. For perform this type on analysis you can select a variation curve for each lithology

The internal database can be updated automatically with a series of standard curves:

  • EPRI (1993) PI = 10
  • EPRI (1993) PI = 30
  • EPRI (1993) PI = 50
  • EPRI (1993) PI = 70
  • SEED et al. (1986) Gravel
  • SEED et al. (1986) Sand - Lower Bound
  • SEED et al. (1986) Sand - Average
  • SEED et al. (1986) Sand - Upper Bound
  • IDRISS et al. (1990) Clay
  • IDRISS et al. (1990) Sand
  • IDRISS et al. (1990) Sand Mean
  • VUCETIC & DOBRI, IP = 0
  • VUCETIC & DOBRI, IP = 15
  • VUCETIC & DOBRI, IP = 30
  • VUCETIC & DOBRI, IP = 50
  • VUCETIC & DOBRI, IP = 100
  • VUCETIC & DOBRI, IP = 200
  • ROLLINS et al. (1998)
  • DARENDELI & STOKOE (2001)

It's can enter any stress functions for Shear Modulus and Damping Ratio.
