Calculation settings

Analysis

You can choose between two sorts of analysis: Geometric non-linear (GNL) or Geometric linear (GL). When you have chosen for a check according to the Eurocode (timber and steel), the analysis is always Geometric non-linear (GNL).

Dead weight

You can choose if you want the dead weight to be automatically generated or not.

Gravity acceleration g

Gravity acceleration in m/s2.

Code check Design working life

The design working life of the construction in years

Consequence class

The consequence class of the construction. This determines among other things, the load factors that need to be used.

National Annex

The national annex can be chosen by land.

Steel code

The steel code you want to use

Imperfections

It can be set whether you want to take imperfections into account or not. For the time being, in Xframe2d global tilt is only possible in two directions. The beam imperfections (beam deformations) are not taken into account. However, the check according to Eurocode does take this into account, by assuming the buckling length equal to the beam length.

m

Relevant for steel structures only: Is the number of columns in a row including only those columns which carry a vertical load NEd not less than 50% of the average value of the column in the vertical plane considered
