Longitudinal reinforcement

This part is dedicated for the input of longitudinal reinforcement. The individual bars can be inserted with the help of the table in the bottom part of the screen. The reinforcement properties are organized in the window "Edit bar", that appears after clicking on the button "Add" (or "Edit" for existing bar) in the toolbar on the left side of the table. This window contains complete properties of the bar (beginning, end, shape, diameter, cover etc.).

Detailed results of the analysis may be displayed in a new window after using the button "In detail". The workspace is able to show diagrams of bending moments, Cross sectional area of reinforcement and utilization. Displayed quantities can be switched on/off in the window "Drawing settings", that can be launched using the button "Diagrams". The results for envelope of all relevant load combinations are displayed as a default. Results for certain load combination can be displayed with the help of drop-down menu in the heading of input frame.

The longitudinal reinforcement in compression may be also included in the analysis. The consideration of this reinforcement in the analysis depends on the setting "Include reinforcement in compression".

The reduction of bending moments at the supports can be switched on with the help of drop-down menu "Moment reduction". These options are available:

Do not reduce

  • Bending moments over the supports aren't reduced. Longitudinal reinforcement is verified using internal forces, that were calculated in part "Internal forces".

Reduce to face

  • The values of bending moments at the edges of supports are used also for the verification along the whole support length. Higher values of bending moments in these positions are ignored.

Reduce as continuous beam

  • Bending moment and shear force are reduced at the support using assumption, that the stress in the support is constant along the whole support length. This procedure is based on chapter 3.3.3. of CSN 73 1201. This theory is valid for continuous beams with simple supports (e.g. slab supported by masonry walls).
