Detailed check of allowable principal stresses

The user may select the section of the beam that should be calculated.

This group shows internal forces in the selected section, enables the user to change the settings and calculate the results.

The designed beam is shown. Mouse cursor may be used to select the required section for assessment.

Pop-up menu may be used to control the view adjustment.

The set of graphical windows presents all the important information related to the design.

Pop-up menu may be used to control the view adjustment.

Any comments accompanying the calculation are listed in this window.

Change of setup

This button opens a dialogue where you can specify what the content of the output document is to be.

Output

This button produces the output either to the Document or to the Preview window.

This value defines the step by which the section is moved if Move cursor left or Move cursor right is clicked.

This value specifies the x-coordinate of the section that is assessed.

Selects a section that is located one step from to the left from the current section.

Analogous to the previous item.

This button is meaningful only for "members" consisting of several parts, e.g. continuous beam where each span is modelled by a separate beam.

It moves the cursor to the previous segment (part).

Analogous to the previous one.

If ON, all the calculations and display regenerations are done automatically once the user changes any value in the dialogue.

If OFF, the use must invoke the calculation manually through button [Calculation].

Selected section

The assessment is carried out for the selected section of the beam.

Extreme section

The program automatically finds the extreme section for the selected quantity and performs the check of this critical section.

Filtered dialogue for adjustment of design parameters is opened on the screen.

Selects the quantity for which the check is performed.

Or if Extreme section is adjusted in the previous group, this selects the quantity for which the extreme is found.

Lists internal forces in the selected section.

Performs the calculation.
