Goal and description

This plugincomponent that is developed using Tekla Open API

Plugin is a .dll file and loaded inside Tekla Structures process.

Plugins can be started from the applications and components catalog.

allows the installation of complementary reinforcement in double walls.

Seven shapes are available for extra reinforcement:

1 - With frame (stirrup)
2 - With U
3 - Shape U with skin shift
4 - Shape U shift and angle
5 - Shape U exceeding
6 - With two frames
7 - With bottle frame

When reinforcements exceed the contours of the walls and require the use of a special formwork (polystyrene) in the workshop, the plugin creates special formwork surfaces with surface treatmentbuilding object that represents finishing of a part

The term surface treatment is used in concrete detailing. For concrete parts surface treatment includes surface mixes, tiles, and flat finishes, such as troweling and sandblasting.

The term surface finish is used in steel detailing. For steel parts surface finishes include fire-proofing and unpainted areas.

. Information regarding special formwork can be displayed on the drawings and used in Unitechnik export.

Possibility to create a formwork part to group all extra reinforcement. The TOTAL_REBAR_WEIGHT user attribute of the part corresponds to the total weight of the reinforcement.

A symbol is displayed in the model viewview that is represented in the modeling mode

Model view is available also in the drawing mode and it is represented in its own window.

to show extra reinforcement orientation.

 

Installation Extra reinforcement

To install the plugin:

If Tekla Structures is not started:
    Download the appropriate TSEP (Tekla Structures Extension Package) file from Tekla Warehouseservice for collaboration and for storing and sharing Tekla Structures content

In Tekla Warehouse the content items are stored in collections. Tekla Warehouse includes the Tekla Warehouse Service and the Tekla Warehouse web site.

Tekla Warehouse is one of the Tekla Online services.

.
    Double-click on the .tsep file.
    In Tekla Structures Extension Manager, select the versions of Tekla Structures for which you want to install the applicationpart of Tekla Structures functionality that is developed in order to extend the capability of Tekla Structures but that is not included in the Tekla Structures installation

.
    Click on "Import".
or
    Copy the .tsep file under .\TeklaStructures\[version]\Extensions\To be installed

    Start Tekla Structures.

If Tekla Structures is started:
    Download the appropriate TSEP (Tekla Structures Extension Package) file from Tekla Warehouse.
    Click on the button menu in the Application & Components side panel and select Extension Manager.
    Click on Import.
    Select the .tsep file and click Open.
    Restart Tekla Structures to complete the installation.

Two plugins will appear in PRECAST group > MCI in the Applications & Components side panelinstaller le plugin:

Using Extra reinforcement

Plugin CFA : select a top, bottom or side face of a wallplate that represents a structure such as a wall or roof panel

In Tekla Structures, a panel is created by picking two or more points.

In cast-in-place concrete the term wall refers to a concept similar to panel.

or opening. Extra reinforcement is automatically placed inside the double wall along the entire length of the selected face according to the parameters in the dialog box.

Plugin CFA 2 points : in addition to the face, select the start and end point of the extra reinforcement.

Tab Section:

1- Extra reinforcement shape (7 different shapes)
2- Parent shell for the extra reinforcement
3- Side cover thickness definition (manual value, automatic 1 meshreinforcement that represents a mesh of steel bars in two perpendicular directions

In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

layer, automatic 2 mesh layers)

4- Extra reinforcement height and ties location
5- Rebar number and properties
6- Extra reinforcement stirrups distribution. Two options: Equal distribution or exact spacing values

Tab Parameters:

7- Redefine position to choose again the face of the wall when the extra reinforcement is in a wrong position after double wall modification
8- Start and End offsetpart property that is used to move the ends of a part, relative to the part’s reference line


9- Vertical offset
10- Option for a skewed extra reinforcement

11- Classpart property that groups parts according to identifiers given by the user

The identifiers of classes are usually numbers. Classes can be used for defining the color of parts in the model, for example. Class does not influence the numbering of model objects.

for special formwork surfaces
12- Main bars, stirrups and ties properties
13- Formwork part creation and properties. The formwork part will group all the reinforcements. Three options: None, ‘Yes -  Link with extra reinforcement’(reinforcements are attached to the formwork part), ‘Yes – No link with extra reinforcement'

Tab Splicing:

14- Option for anchoring or splicing with splicing length parameter (auto=-1)

15- Option for bar end shape (none, 90° or 135° hook). Parameter for anchoring or splicing length (auto=-1)

16- Option for material (list of materials defined in CFA.inp file). Option for seismic.  Parameter for aggregate diameter (mm)

When the user ask for three main bars, the aggregate diameter is used for cover thickness calculation between the second and the third barl:

Value = max (20 mm, main bar diameter, aggregate diameter + 5 mm)

For anchoring and splicing length, the user can set a value or ask for an automatic calculation (-1).

Configuration

Automatic radius and length of the 90° and 135° hook are defined in the rebar configuration file (rebar_database.inp)

Automatic length of anchoring/splicing is defined in the configuration file Environments\common\extensions\CFA\CFA.inp (length = main bar diameter x factor according to material and seismic option)

General parameters are defined in the extension configuration file Environments\common\system\CFA.config.xml

codeRegle: line attribute for contour used for Unitechnik export. The value is added as UDAobject property created by the user in order to widen the range of predefined object properties

User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

to surface objects for special formworks.
colorST: color of surface treatment in the model view for special formworks. Seven colors available: White, Red, Green, Cyan, Blue, Yellow and Magenta.
