Scage is a software package dedicated to the structural analysis of geotechnical structures. In particular, it allows the internal balance of piles and diaphragms wall to be determined in accordance with Eurocode 2 (French and Belgian national annexes) and the French national application standards of Eurocode 7 (NF P 94-262 and NF P 94-282).

Structural analysis of piles

Scage offers two types of analysis for performing structural analysis of piles:

  • Detailed verification module: it allows the verification of a reinforcement cage for a set of internal force diagrams resulting from a soil-structure interaction calculation (import of internal efforts from Foxta, K-Réa or Excel). The calculation is performed phase by phase (ULS and SLS) in simple, compound or deviated bending.
  • Simplified predesign module (available soon): it allows to decide on the diameter and the reinforcement ratio of the piles required to support one or several load cases, for an infinite number of piles. It also allows to estimate the maximum forces at depth according to the forces applied at the head for each combination/situation considered.

Structural analysis of diaphragm walls

Scage offers two types of analysis for the structural analysis of diaphragm walls:

  • Predesign analysis: this allows the necessary longitudinal steel sections to be obtained at the ULS and SLS, as well as the necessary transverse steel sections at the ULS. The internal stresses of the diaphragm wall are considered as input data from a soil-structure interaction calculation (ISS calculation performed for example with K-Réa) taking into account the construction phase of the structure. The calculation is performed for each phase in simple or compound bending.
  • Design or verification of a reinforcement cage: this is the verification of the suitability of an actual reinforcement cage defined by each longitudinal steel bar and each overlapping hoop. The center of gravity of the longitudinal steels is rigorously evaluated according to the bars present at each level. The calculation of the crack opening is performed at any level by the exact method.
