Cross sections

Cross section data  



  • Relative Distance: Length per segment to which the entered data applies. In the above dialogue, as an example, a strip has been used that has different cross-sectional properties from 0 to 2 mtr, from 2 to 5 mtr and from 5 to L (7 mtr).
  • Absolute distance: derived value, depending on the relative distance entered.
  • Cross-section: definition of the cross-section. By pressing the ... button, a new dialog appears in which the cross-section can be defined. Cross-sections can be parameterized or selected from a library.


  • This dialog appears when using the ... button in the table.
  • By checking the Bi-material checkbox, an input field appears for:
  • hT: height of the top layer [m]
  • hB: height of the formslab [m]
  • bB: width start [m]
  • bE: width end [m] (only applicable for tapered cross-sections)
  • MaterialT: concrete quality of the top layer
  • MaterialB: concrete quality of the formslab
  • R1000x(200+50): syntax name derived from this input example:



  • If the properties are the same over the entire strip, it is sufficient to enter L at relative distance.
  • The syntax name from the input dialog is shown in the table.
  • This syntax name can also be entered directly into the table, without using the input dialog: 



  • Reinforcement: Default is None. Then MatrixFloor designs proposals for reinforcement.
  • Standard reinforcement configurations can be used. These can be predefined in a library. If a library is available, these options appear in the Reinforcement drop-down list.
  • Alignment: If there are profile cross-sections with different heights, it is possible to set via Alignment how the relevant cross-section should be aligned with respect to the previous one: top equal, bottom equal or in the neutral line.
  • Environmental class and coverage: For the Top, Bottom and for the Side, the environmental class and coverage can be set individually. 




  • Quality: selection list for the concrete quality of the formslab.
  • Cement: selection list for the cement class of the formslab.
  • Surface: roughness of the bonding surface: Very smooth, smooth, rough or serrated.
  • Stirrups in prefab: stirrup reinforcement does/does not contribute to the shear capacity between the formslab plate and the top layer.



  • Quality: selection list for the concrete quality of the top layer.
  • Cement: selection list for the cement class of the top layer.
    f;ck;t0: concrete compression stress at time t0.
