LRFD - Analysis of Retaining Walls (Support Structures)
Analysis according to LRFD introduces two types of design coefficients - coefficients modifying the load magnitude (Load factors) and coefficients reducing the soil resistance (Resistance factors).
These coefficients enter the analysis according to the selected design situation.
When evaluating individual cases of a failure, the program determines, whether the force or pressure acts favorably or unfavorably. It is then multiplied by the corresponding partial factor.
When performing the final verification, the overall resistance of the structure against failure is multiplied by the corresponding resistance factor.
Analysis based on LRFD - input of partial factors for wall analysis
For support structures (walls), the information about the applied design factors is provided in the analysis protocol.
