Verification according to EN 1997

Analysis according to EN 1997 is verified according to the limit state theory.

When performing the verification analysis according to EN 1997 in combination with design approach 2 the program reduces the resisting moment (by reciprocal value of γRs). The value of capacity utilization Vu is calculated and then it is compared to 100%. The value of capacity utilization is given by:

where: Movr - overturning moment
γRs - resistance on slip surface reduction factor
Mres - resisting moment

In the case of design approaches 1 and 3 the program reduces the strength parameters of soil (angle of internal friction and cohesion). The value of capacity utilization is then given by:

where: Movr - overturning moment
Mres - resisting moment
