The new load combinations are defined in the Load Combinations Editor by entering a load factor to the different loads acting on the dam (Figure 164). The nomenclature used (N1, I1, I2, E1, etc.) corresponds to:

  • N :        normal conditions (normal operating conditions)
  • I :        unusual conditions (unusual ice, blocked drains, post-seismic)
  • E :        extreme conditions (safety floods, maximum earthquakes )
