Predefined functions and constants
|
Basic mathematical functions such as "sin", "cos", "tan" and "exp" as well as the constant PI are available.
Functions of station:
The use of these 3 functions makes sense only for the input in the variable list at segment points.
Functions of station of the father segment (for piers, cross members):
sgf, slf, and spf – These 3 functions correspond to the ones above, but the results of them are the station of the father segment, i.e. sgf used at a pier point returns the station of the connected main girder at the connection position.
Functions for evaluating the angle of a percentage value:

Formulas
|
Formulas consists of a name to be identified, a mathematical expression, its current value, its type and an additional description.
The type of a formula is related to the types of variables in the cross section "Length", "Angle", "without dimension").
The formulas are limited by 31 characters.
The description is a optional property and is used as a help for the user.

Tables or diagrams
|
Tables consists of a set of expressions for abscissa and ordinate. These expressions are arithmetical terms of constants and defined formulas.
The Interpolation between two points of the table can be entered:
|
Input
|
The window for formulas, tables, and shapes consists of two lists. The upper list contains the names of the formulas and tables as well as their parameters. The lower list is valid for tables and shapes only and shows the items of the active entry in the list above.
Note: Formula and table names must not consist of mathematical symbols like '-', '+', '.', etc. . Names start with any letter ('A'-'Z', 'a'-'z') and may have the character '_'. German letters and other non-regular characters are to be avoid.
|
Insert a formula / table
|
If the list of formulas is active, the Insert before or Insert after tools in the left vertical symbol column can be used to insert a new formula or table. Formulas and tables are sorted by name. Hence, both symbols have the same meaning.
|
Modify a formula / table
|
A selected formula or table can be modified using the Modify tool in the left vertical symbol column.
|
Delete a formula / table
|
A selected formula or table can be deleted using the Delete tool in the left vertical symbol column.
|
Graphic display of a table
|
Each table can be interpreted as a diagram. The diagram of the selected table will be shown in a separate window if the Info tool is pressed.
|
Work on a tables
|
The edit symbols in the left vertical symbol column are reserved for the upper table. That's why, analogue symbols in the current window are offered and have these ones have to use.
|
Insert a table entry
|
Using the Insert before or Insert after tools, a new entry can be inserted before or after the chosen table position, respectively.
|
Modify a table entry
|
A selected table entry can be changed using the Modify tool.
|
Copy table items
|
To input periodic tables easier, it is possible to copy a sequence of table items. First, the sequence to be copied has to be marked ( first and last row ). Then select the desired insert position. Now, copying has to be executed by pressing the Copy button in the bottom of the current window.
|
Delete a table entry
|
A selected table entry can be deleted using the Delete tool.
