Anchor properties from file

You can define lifting anchor properties by entering values in the dialog box

(see

Lifting anchor properties (page 593) ), or you can create a file containing

the anchor properties you want to use. Use any standard text editor to create the file and save it as LiftingAnchors.dat in the model folder.

To use the anchor properties you define in a file:

1. In the Lifting anchor (80) dialog box, select Select from file from the

Anchor dimensions list box.

2. Click the ... button to browse for the file.

Example

Create a row in the file for each lifting anchor. Enter the following properties, separated by spaces:

• Anchor capacity [kN], including safety and material factors

Reinforcement 596 Lifting

• Type [A, B, C, or D], see the Use for table in Lifting anchor (80) (page 591)

• Grade [characters]

• Size [characters]

• Anchoring length 1 [mm]

• Anchoring length 2 [mm]

• Protruding dimension of the anchor outside the part [mm]

• Penetrating dimension of the anchor inside the part [mm]

• Bending radius [mm]

• Hook length [mm] (0 = no hook)

• Angle of leg 1 [degrees]

• Angle of leg 2 [degrees]

Here is an example of a lifting anchor file (Tekla Structures ignores the comments enclosed in /* */):

Tekla Structures will use the first anchor in the file that:

1. Has the shape and type you define using the graphic list boxes in the

Lifting anchor (80) dialog box.

2. Can carry the part’s weight with other identical anchors. The total number of anchors is two times the number you specify in the Number of bars field.
