Footing Verify

 

Launch the Verify command to perform a verification considering the real reinforcement in place. Useful to be used after the Constructive Dispositions command is applied, when reinforcement cage is customized after calculation or when the reinforcement cage is manually defined from scratch.

 

Errors and Warnings

When applying the Calculate, Footing Presizing or Verify commands, the Errors and warnings tab in the console displays warning and error messages regarding the design of the footing.

• Numerical inconsistencies found (equation F.1 from EN 1998-5/NA)

• The soil settlement is exceeded (SLS)

• Seismic bearing capacity cannot be calculated. Condition on N normalized, F.5 from EN1998-5, is not satisfied

• Seismic bearing capacity cannot be calculated. Condition on N normalized, F.8 from EN1998-5, is not satisfied.

• The supported element does not respect the pedestal condition, so it will be calculated as a column

• The spacing of the bottom reinforcement on X does not meet the minimum conditions

• The spacing of the bottom reinforcement on Y does not meet the minimum conditions

• The spacing of the top reinforcement on X does not meet the minimum conditions

• The spacing of the top reinforcement on Y does not meet the minimum conditions

• A convergence problem was encountered. The pressures distribution can't be calculated with precision for this foundation because in horizontal plane, it results as a pentagon having one of the edges too small.

• Invalid reinforcement generated. (Review the geometry of the element)

• Seismic bearing capacity (Nmax) is exceeded. The condition on V normalized (eq. F.5 (§F.2) from EN1998-5) is not satisfied.

• Theoretical reinforcement area is greater than maximum reinforcement area, reinforcement cage for supported element was not generated

• Seismic cases are defined but seimsic bearing capacity verification is not activated (in Design Assumptions - Seismic Design)

• The chosen distribution type could not be generated because the required anchorage length could not be provided. Standard distribution has been generated instead.

• The footing height is not enough to consider this footing as pure concrete. Either increase footing height or change calculation type to reinforced footing

• The reinforcement calculation could not be performed for at least one combination because the load eccentricity exceeds the scope of the calculation method (ex > 0.5 * A or ey > 0.5 * B).
