Analysis According to LRFD

When performing analysis according to LRFD (Load Resistance Design Factor) we follow the theory of limit states.

The analysis according to LRFD introduces two types of design coefficients:

  • coefficients modifying the load magnitude (Load factors)
  • coefficients reducing the soil resistance (Resistance factors)

The program allows verification according to two methods of the analysis, LRFD 2003 or LRFD 2012.

LRFD 2003 is implemented in the program to perform:

  • Analysis of retaining walls (support structures)
  • Analysis of spread foundations

LRFD 2012 is implemented in the program to perform:

  • Analysis of retaining walls (support structures)
  • Analysis of spread foundations
  • Slope stability analysis

LRFD 2012 introduces new types of design situations (Strength I, Service I, Extreme I).
