Unitechnik export: Reinforcement tab

Unitechnik export: Reinforcement tab

Use the Reinforcement tab to control the Unitechnik export properties.

You can export single reinforcing bars, groups of straight and bent reinforcing bars, and rectangular or polygonal or bent meshes. The reinforcing bar groupgroup of reinforcing bars that are side by side and have identical properties, except the possible variation in bar lengths

, or rectangular or polygonal 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.

is divided into several single reinforcing bars. All reinforcing bars are exported in the RODSTOCK block.

Option

Description

Rebars export

When set to Yes , straight reinforcing bars are exported. Hooks are supported. You can define the setting separately for straight or bent rebars.

Meshes export

When set to Yes , polygonal or rectangular meshes are exported. Hooks are supported. You can define the setting separately for straight or bent meshes.

You can also select whether to unfold along longest line or parallely to pallet.

Bent reinf. as unfolded

When set to Yes , bent reinforcement is exported as unfolded. Hooks are also supported for unfolded reinforcement, and you can select Yes, with end hooks. Hooks form 0, 2 and 5 are detected.

You can select between two reinforcement starting points: Origin in unfolded rebar or Origin in start rebar point. The option also affects the z level of the reinforcement in the resulting Unitechnik file.

Export meshes as

Set the rotation of the mesh plane in the export file. The options are:

Standard

Embeds : Exported as mountparts.

Turned to pallet : All meshes will be individually rotated in line with the pallet axes.

Braced girder classes

Enter the class of reinforcing bars, steel rods or profiles representing braced girders. For example, 15 17 5 means that parts with class 15, 17, or 5 are considered braced girders. If the Braced girder export and Braced girder classes boxes are not used, the braced girders will be exported incorrectly as reinforcement or embeds.

Reinforcement export type

Define the structure of the exported file for reinforcement.

Plant with lying robot only

All embeds without modifications are exported.

Fabrication of welded rebars

If Export type is set to Fabrication of welded rebars , a single reinforcing bar is exported in one STEELMAT block, all reinforcing bars of one group are exported together in one STEELMAT block, and all reinforcing bars of one mesh are also exported together in one STEELMAT block.

The structure of the output file (one SLABDATE is shown only):

 

Collect reinforcement

The structure of the output file is the same as for Fabrication of welded rebars. This option allows you to collect mesh, single reinforcing bars and reinforcing bar groups into groups exported in one STEELMAT block. The groups are collected based on the Collect based on field. You can also collect meshes which belong to different cast units.

1 (orange color): The mesh belongs to the bottom panel of the cast unit, mesh name is MESH1.

2 (blue color): Two single bars, the name is MESH1.

3 (green color): One reinforcing bar group belongs to the top panel, the name is MESH1.

If Reinforcement export type is set to Collect reinforcement and Collect based on is set to Name , all three different reinforcement types are collected into one mesh, which is exported in one STEELMAT block.

Meshes as MOUNPART

Meshes are exported in the MOUNPART block.

Collect based on

Select how meshes are collected. Meshes with one bar are exported as a single reinforcing bar.

  • Name

    Meshes, single reinforcing bars and reinforcing bar groups with the same name are collected into meshes. Meshes, single reinforcing bars and reinforcing bar groups with the same name equals one mesh in the exported file.

  • Class

    Meshes, single reinforcing bars and reinforcing bar groups with the same class number are collected into meshes. Meshes, single reinforcing bars and reinforcing bar groups with one class number equal one mesh in the exported file.

  • Grade

    Meshes, single reinforcing bars and reinforcing bar groups with the same grade are collected into meshes.

  • UDA

    Meshes, single reinforcing bars and reinforcing bar groups with the same user-defined attribute are collected into meshes.

    The value you enter in the box next to this option is the UDA value.

Collect if distance is lower then

Define the maximum distance between the meshes to be collected.

Reinforcing bars length

Select how the reinforcing bar length is calculated.

  • Lines in the middle

 
  • Lines at the edge

 
  • GetValue(Length)

Reinforcing bars diameter

Select how the reinforcing bar diameter is exported.

This selection affects the results of the Rebar length option.

Rebar direction angle limit

Select whether the reinforcing bars are sorted according to their angle direction.

  • No

    The reinforcing bars are not sorted.

  • From 0 to 180

    The reinforcing bars are exported as they are read from Tekla Structures and sorted according to their x and y position.

  • From 0 to 180 ordered

    The reinforcing bars are sorted according to the direction angle of the reinforcing bar: the reinforcing bars with lower angles are first.

  • From 180 to 0 ordered

    The reinforcing bars are sorted according to the direction angle of the reinforcing bar: the reinforcing bars with higher angles are first.

Reinforcement types

Select the reinforcing bar type in a mesh to be exported.

1 and 2 are for the rods in the bottom layer.

5 and 6 are for the rods in the top layer.

4 is for other or inclined rods.

8 is for loose bars.

Classes for loose rebars type 8

Enter the classes of loose reinforcing bars to be collected. The bars are a part of a mesh and are exported as reinforcing bar type 8.

Classes for non-automated rebars

Enter the classes of non-automatic reinforcing bars to be collected.

Spacer type

You can add spacer type information to the first layer of the reinforcement (Unitechnik reinforcement type 1). The spacer type is added to the respective spacer type block in the rodstock within the Unitechnik file. The options are:

Automatic : Calculates the spacer type automatically according to the cover thickness. The cover thickness is divided by 5 and rounded up to the nearest integer. For example, if the cover thickness is 21 - 25 mm, the spacer type is 5, and if it is 26 - 30 mm, the spacer type is 6.

User defined spacer type : Enter the spacer type to be input in all first layer rebars.

No : Leaves 0 as spacer type.

Add mesh stabilizing wires

Select whether to add wires to the reinforcement mesh to stabilize the mesh. Use for meshes with large openings.

Stabilization wire max spacing

Enter a value to define the maximum spacing of the wires that stabilize the reinforcement mesh.

Meshes sort

Select whether meshes are sorted.

Meshes offset

Select whether the mesh has an offset defined in the STEELMAT block. If the option is set to Yes , the value for X and Y direction is set to zero. If the option is set to No , the X and Y values are exported according to modeled situation.
