Improvements in components

Improvements in components

There are several improvements in concrete components and steel components in Tekla Structures 2019.

Concrete components

Embedded anchors (8)

On the Placement tab, it is now possible to move anchors to the closest braced girder. You can select the 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.

and name of the top braced girder bar, and also the maximum displacement of anchors.

Automated reinforcement layout - double tee beam (51)

On the Strand pattern tab, you can now use an external .CSV file to define an infinite amount of individual strands.

Automated reinforcement layout - ledge spandrel (55), Automated reinforcement layout - rectangular spandrel (56)

  • Stem stirrup and ledge rebar creation has been changed so that the user input spacing value is not exceeded when using Both in the Spandrel End option. In most cases, this means that in the middle there are two smaller spacings than the input value.
  • You can now define advanced hook properties for rebar groups on the Stem stirrups (for 55) and Ledge rebar tabs. The components are not fully backward compatible with older versions due to these improvements.

Ledge spandrel - automated reinforcement layout (55)

  • You can now control the secondary rebar set on the End rebar tab.

Beam reinforcement (63)

You can now select to create additional links on the Parameters tab.

Stirrup reinforcement (67)

You can now rotate the rebar polygon clockwise at each even or odd positions. Entering a value, for example 1,2,3 or 4, in the First stirrup box rotates the rebar polygon at odd positions and entering a value in the Second stirrup box at even positions.

Strip footing reinforcement (75)

You can now create double stirrup bars as a new bend type on the Stirrups tab. Transverse settings are now on the Stirrups tab and the bending direction is shown as images.

Seating with dowel (75), Two sided seating with dowel (76) , Seating with dowel to flange (77), Two sided seating with dowel to flange (78)

You can now create a bearing plate(1) part that represents a flat structure

(1) In some contexts, for example in analysis, the term plate object may be used to refer to plates.

(2) plate that represents a steel structure

(2) Plate is mainly used as a connection piece or as a floor plate.

relative to the column. Two sided seating with dowel to flange (78) is not fully backward compatible with older Tekla Structures versions due to the improvements.

Round column reinforcement (82)

You can now select on the Advanced (main bars) tab whether to cut the created rebars by the cut in the father part or not.

Rectangular column reinforcement (83)

  • You can now select whether all the stirrups are created as a single group on the Intermediate links tab.
  • You can now define gaps between the stirrup groups on the Stirrups tab.

Hole reinforcement for slabs and walls (84)

  • You can now reinforce an already existing holesmall hollow open throughout a part or assembly that is usually used for fastening parts with bolts or other such objects

    Hole is created in the same way as bolts and hole properties are defined in the bolt properties.

    and apply position offset for a hole that you are creating.

Started bars for footing (87)

With the new Bottom cover tab, you can now set a separate unique bottom cover thickness for each bar group. The other option is to set a common bottom cover thickess for all corner bars and side bars.

Reinforced concrete stair (95)

  • You can now select whether to create finished floor level on the Parts tab. The finished floor level is defined by a polygon created from an offset stairs polygon and it is used for drawings. Define the profile, properties and offset of the dummy part that is created at each polygon vertex.
  • You can now create reinforcement in stringers on the new Stringer bars tab.
  • On the Bar C tab, there is an option for a new rebar landing shape and a setting for adapting the nose shape.
  • On the Bar E tab, you can now select to create stirrups and pins parallel with the sloped edge of the step.
  • On the Bar K tab, there is an option for a new rebar shape and its appropriate I bars.
  • On the Bar L tab, you can now define whether reinforcing bars are created between the top and bottom step.

  • On the Parameters tab, there is a new shape for the bottom landing.

  • You can now define the name, prefix and start numberfirst number of a numbering series

    for each type of rebar and 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.

    on the Mesh bars , Bottom anchor bars , Top anchor bars , and Z anchor bars tabs.

Concrete console (110)

  • You can now define the offsets for the tube profiles in both the X and Y directions on the Anchor rods tab.

  • You can now use the Legs symmetrically setting on the Socket tab to select whether custom partcomponent for creating a part that cannot be created by using any existing part command or part profile

    Typically, custom parts are used to create parts that have a complex composition. For example, castellated beams and sandwich panels are often created as custom parts.

    sockets are created symmetrically.
  • On Parameters tab, you can now find and cut extra secondary parts using classes or name search. You can also define the maximum width of the secondary part(1) part that exists in a building object and that is connected to the main part

    (1) Secondary part can be an assembly secondary part or a cast unit secondary part.

    (2) input part that the user selects after selecting the component main part when creating a component

    (2) A component can have none, one or more component secondary parts.

    and cut it to this width.

Concrete beam-beam (112)

  • When defining the neoprene, you can now select on the Parts tab whether the neoprene is fitted to fill the cut space between the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

    (1) Main part can be an assembly main part or a cast unit main part.

    (2) input part that the user selects first when creating a component

    (2) Connections and details always have a component main part.

    and the secondary part, or whether it is created in a rectangular shape.

  • You can now select on the Anchors tab whether the tubes are aligned with the main part, or with the top or bottom of the secondary part.

Double wall edge and opening reinforcement

There is a new cover thickness offset C3 on the Picture tab. New options have been added for edge and opening reinforcement (not reinforcement and create just stirrups) on the Reinforcement and Opening tabs.

Mesh bars

You can now control the minimum length of primary and secondary bars separately.

Rebar coupler, Rebar end anchor

  • Rebar coupler and Rebar end anchor components have been changed so that when used with rebar sets, the end-specific 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.

    values are set with end modifiers. For rebar sets, the end modifierline or polyline that can be used to locally modify reinforcing bars in a rebar set

    Rebar set modifiers can be rebar set property modifiers, end detail modifiers, or splitters. Also rebar set secondary guidelines behave like rebar set modifiers.

    Polyline modifier may have corner chamfers. Each rebar set modifier only affects those rebar set reinforcing bars that its projection touches.

    properties thread length, extra fabrication length, and threading type values of the end modifier are set (instead of custom UDA values).

    Note that to get the threading type controlled by coupler / end anchor components, this value must be added to the RebarCoupler.Udas.dat file.

  • Rebar coupler has been changed so that the free space between two rebars can be controlled with a new dimension attribute on Attributes tab. You can set this value manually or with the auto attribute file.

    Rebar end anchor has been changed so that when it is used with rebar sets, the rebar is shortened with the given offset so that the anchor will have the same cover distance as the original bar end. The concrete cover can be automatic or overridden with the (input) end detail modifierrebar set modifier that can be used to create hooks or threading for certain reinforcing bars in a rebar set

    The rebar set end detail modifier affects the nearest end of the reinforcing bar.

    .

Wall layout

  • When customizing the content of the UDA tab, you can now define in the WallLayout.Udas.dat file that layer UDA values are not swapped when the Wall layout layer swapper tool is used. You can do this by adding NoSwap at the end of the line (fourth field): string comment j_comment NoSwap.
  • Wall layout has been modified so that the Geometry detailing strip at the top/bottom is extended by default by the extreme of the part edges.

Wall layout T connector

The Add seam setting now has a new option First layer only. With this option, only the first layer is split into two parts. Previously, the No option has this functionality. The No option now does not split the first layer part, instead a cut that breaks the part into two solid objects is created.

Wall groove seam

You can now use the new Create fitting option on the Edge shape tab to control whether the part end fittingadjustment of a part end

is created.

Wall groove seam, Wall to wall connection

  • You can now control the location of the last rebar/embedbuilding object that represents an object that is to be cast into a concrete structure and that is used to connect structures or as an aid when constructing a structure

    For example, a cast-in socket is an embed that is placed in concrete structures to allow parts to be bolted together on site. In Tekla Structures, embeds are modeled as steel sub-assemblies that are inside a concrete nested assembly.

    in the 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.

    top edge on the Connectors tab.
  • There is a new edge shape option on the Edge shape tab. With this option you can create a groove where one of the noses can be shortened by a given distance.
  • You can now control the offset of the loose bars at the bottom of the connection/start of the seam on the Connectors tab.
  • There is a new Thickening tab where you can create extra thickening to walls.
  • You can now select to create part cuts or only extra part cuts, and define the name of the cut. In Wall to wall connection , you can set this separately for both walls. For part properties of extra part cuts, select a saved settingsmaster drawing where the drawing settings are saved in a drawing property file and used when creating a new drawing of a specific drawing type

    file.
