Property modifier properties
Use the property pane or the contextual toolbar to view and modify the properties of the rebar set property modifiers. The file name extension of the property file is .rst_pm.
User-definable name of the bars.
Tekla Structures uses bar names in reports and drawing lists, and to identify bars of the same type.
Steel grade of the bars.
Grade-size-radius combinations are predefined in the rebar catalog. Click the ... button in the property pane to open the Select rebar dialog box. The dialog box shows the available bar sizes for the chosen grade. You can also select whether the bars are main bars, or stirrups or ties.
Diameter of the bars.
Depending on the environment, the nominal diameter of the bars, or a mark that defines the diameter.
Internal radius of the bends in the bars.
Bending radius complies with the design code you are using. Main bars, stirrups, ties, and hooks usually have their own minimum internal bending radii, which are proportional to the diameter of the reinforcing bar. The actual bending radius is normally chosen to suit the size of the mandrels on the bar-bending machine.
Automatic values are shown in square brackets, for example [120.00].
Used to group reinforcement.
For example, you can display bars of different classes in different colors.
|Numbering||Numbering series of the bars.|
Select whether the property modifier attempts to follow the leg face edges that are located between the modifier end points.
Select whether the property modifier affects the bar spacings.
If you select Yes, the Distribution properties become available, and Bars affected and First affected bar are unavailable.
Select how many bars can be modified in the same location:
|First affected bar||
Define which is the first bar to be modified, starting from the first end of the modifier.
Enter a positive number, or use the arrow buttons to change the number.
|Affect whole bar plane||
Select whether the property modifier affects all bars of a rebar set that are in the same plane even though some of the bars are not touched by the property modifier (or its projection).
For example, to modify bars on opposite sides of an opening using the same modifier, select Yes.
Select whether and how the bars that are affected by the property modifier are grouped. The options are:
These properties are available when Modify distribution is set to Yes.
The offsets at the start and end of the modifier.
Automatic values are shown in square brackets, for example [32.00].
Note that the automatic offset values may change if the outermost rebar set bars are split by splitters and the split bars would end up in the concrete cover area.
How the bars are spaced. For more information, see Spacing options.
|Number of reinforcing bars|
|Target spacing value|
|Exact spacing value|
|Exact spacing values|
Which bars are omitted from the rebar set.
See also Examples.
Define whether the lengths of straight bars, first and last legs, and intermediate legs are rounded, and whether the bar lengths are rounded up, down, or to the nearest suitable number according to the rounding accuracy.
|First and last legs|
|Rounding up at splitters||
At splitter locations, define how much the bar lengths can be rounded up.
Advanced: Step tapering
Define whether the bars are step tapered, and how the tapering steps are created.
The options are None, Distance, and Number of bars.
If you select the Number of bars option, enter the number of bars in one tapering step.
If you select the Distance option, enter the tapering step values for straight bars, first and last legs, and intermediate legs.
|First and last legs|
Advanced: Minimum lengths to be created
|Minimum bar length||
Use to prevent Tekla Structures from creating reinforcing bars that are too short. This setting is primarily for straight bars. Enter the minimum bar length as Distance or as Coefficient of bar diameter.
|Minimum straight start/end leg length||
Use for bent reinforcing bars. Enter the minimum leg length as Distance or as Coefficient of bar diameter.
Click the User-defined attributes button to open the user-defined attributes of the rebar set property modifiers. The file name extension of the user-defined attribute file is .rst_pm.more.
You can use user-defined attributes to define or override settings, such as bar layer prefix and number, or grouping settings.
