Abutment - Bridge abutments and wing walls analysis

The program serves to verify abutment design. It allows for checking the abutment for overturning, translation, bearing capacity of foundation soil and for dimensioning of decisive concrete or reinforced concrete sections (including wings), respectively.

Main Features

  • Verification analysis can be performed employing EN 1997-1, LRFD or classical approach (limit states, factor of safety)
  • EN 1997 – option to choose partial factors based on National Annexes
  • EN 1997 – option to choose all design approaches, consider design situations
  • Large number of possible wall shapes
  • Earthquake effects (Mononobe-Okabe, Arrango)
  • Check of concrete cross-sections according to various standards (EC2, BS 8110, IS456, CSN, PN)
  • Verification of wing walls
  • Analysis according to the theory of limit states or safety factor
  • Generally layered soil environment
  • Built-in database of soil parameters
  • Arbitrary number of surcharges applied to structures (strip, trapezoidal, concentrated load)
  • Arbitrary number of inserted forces (anchors, safety fences, etc.)
  • Modelling of water in front of and behind structures, modelling of artesian water
  • Analysis of internal stability (overturning, translation, load-bearing capacity of foundation soil)
  • Verification of construction joints and wall keys
  • General shape of terrain behind the structure
  • Berms in front of the structure
  • Various types of pressures in front of the structure (at rest, passive, reduced passive)
  • Calculation of earth pressures in effective and total parameters
  • Earthquake effects (Mononobe-Okabe, Arrango)
  • Multiple construction stages
  • Verification of external stability of a wall using program Slope Stability
  • Analysis of bearing capacity of foundation soil in program Spread Footing
