Spread Footing

This program is used for the design of spread footings (spread or strip footing) subject to general load. It computes vertical and horizontal bearing capacity, settlement and rotation of a footing, and determines required longitudinal and shear reinforcement (punching).

Description

  • Analyses are based on a large number of theories (EC 7, PN, IS, Brinch-Hansen, Meyerhof, Vesic, DIN 4017, CTE-DB SE-C)
  • Various theories of settlement analysis (Janbu, NEN-Buismann, Soft soil, using index and coefficient
  • of compression, secondary settlement according to Ladd)
  • EN 1997 – option to choose partial factors based on National Annexes
  • Verification analysis can be performed employing EN 1997-1, LRFD or classical approach (limit states, factor of safety)
  • EN 1997 – option to choose all design approaches, consider design situations
  • Design of reinforced concrete according to EN 1992 (EC 2), BS, PN, IS, ACI, GP, SNiP, CSN
  • Shapes of foundation – centric, eccentric, strip footing, circular, stepped centric, stepped eccentric, stepped circular, spread footing with haunch
  • Automatic design of dimensions of spread footing foundation
  • Generally layered soil environment
  • Built-in database of soil parameters
  • Arbitrary number of load cases
  • Modelling of water
  • Modelling of sand-gravel cushion (SG bed)
  • Modelling of parameters between soil and footing bottom (friction coefficient, friction base-soil)
  • Analysis of foundations on drained, undrained or rock subsoil
  • Inclined shape of grouted slope
  • Inclined footing bottom
  • Verification of load eccentricity for bearing capacity and settlement
  • General shape of stress diagram under the footing due to combined bending and tension/compression
  • Verification of spread footing in tension (standard, cone method, DL/T 5219-2005, BS EN 50341)
  • Settlement analysis exploiting the oedometric modulus specified by the oedometric loading curve
