Improvements in components

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

Concrete components


Rectangular area reinforcement (94)

You can use the new Rectangular area reinforcement (94) component to reinforced rectangular areas. You can create column and beam section reinforcement to the inside of a wall or a slab.

Select the part where the reinforcement is placed and pick two points to create the reinforcement. The part defines the thickness of the reinforced area, and the two points define the geometry and the location of the reinforced area.

Automated reinforcement layout - Double tee beam (51)

On the Strand profile tab, a new option has been added to depress the strand in 3 positions instead of 2 positions.

Pad footing reinforcement (77)

You can now define custom hooks for the primary and secondary rebars.

Round column reinforcement (82)

  • On the Main bars tab, you can now define the horizontal dimensions of the top and bottom cranked bars as a distance between the center of bars or as the outer distance of bars.

  • On the Advanced (main bars) tab, you can now select whether the main bars are created as a rebar group or as single rebars.

Braced girder (88) , Braced girder (89)

There are now two new girder shapes available.

Rebar in beam (90)

On the Stirrups , Stirrups 2 and Stirrups 3 tabs, you can now select in Create stirrups whether stirrups are created As separate groups or As one group. Define the stirrup group spacings for the separate groups on the stirrup spacing tabs.

Reinforced concrete stair (95)

  • The stairs part now has a new STAIR_WIDTH_TOTAL UDA that counts the total stair width including the stringers.

  • For bar type H, you can now set the name, class, prefix and start number separately for the top and bottom rebar.

  • You can now enter a comment in the Comment box for all types of rebars that the component creates.

  • On the Stairs and landings tab, you can now create openings or recesses (screed tray) in the bottom or the top landing.

    The rebars defined on the following tabs automatically avoid the openings created by these new opening/recess options: Bottom anchor bars , Top anchor bars , Z anchor bars , Mesh bars (top/bottom), Bar A , Bar B , Bar C , Bar E , Bar G , Bar K , and Landing end bars (bottom/top).

Concrete console (110) , Concrete console (111)

On the Connection tab ( Concrete console (110) ) and Anchor tab ( Concrete console (111) ), you can now enter 79 characters in the Tube bottom Comment box. Previously, you could only enter 19 characters.

Note that due to this change, the components and property files created with older Tekla Structures versions may have incorrect content in the Comment s of Tube bottom and Washers. We recommend that you check and update your property files.

Floor layout

  • On the Advanced tab, you can now use the Create cut-outs option to control whether the cut-outs (notches or openings) are created for the slabs. If you set the option to No , the slab is created without any cuts. Slabs at break lines or openings which are cut at the whole width are still split and created as two or more slabs.

    Note that the other options on the Advanced tab related to the minimum slab width/neck width still control whether the slab is created/split or not.

    You can create automatic cut-outs for parts penetrating the floor layout areas by entering up to three lists of part classes or names.

  • On the General tab, you can now select to create slabs and parts by default part width or maximum part width, or the number of parts.

  • You can now enter a negative value for the break line offset on the Default offset tab.

Wall layout

You can now use the Copy special > Mirror and Move special > Mirror commands to mirror wall layouts.

Wall panel reinforcement

  • On Picture tab, there is now a minimum bar length option that you can use for filtering rebars smaller than the defined length.

  • On the Picture tab, you can now define the top and bottom extra offset.

Double wall edge and opening reinforcement , Wall panel reinforcement

You can now define the type of door and notch reinforcement on the new Door and Notch tabs.

Sandwich and double wall

  • On the Parts tab, there is now a new material definition option for insulation, Edge strips in split case , which can be used to define a different material for the insulation parts that are on the edge of the wall.

  • On the Parts tab, you can now set the cast unit type of the inside shell, insulation, and outside shell. Set the Cast unit type to Enabled to do this.

  • On the Vertical section tab, there is a new option for creating concrete all over the top surface.

    In the list of thicken innershell options, select

    to cover the insulation and the outer shell.

Sandwich wall horizontal seam

On the Rabbets tab, you can now select a tongue or groove joint connection for both sides of the sandwich wall. If you create one tongue and one groove connection, it is possible to have the parts overlap.

Mesh bars/Mesh bars by area

  • When detailing without grid on the Detailing tab, you can now select whether the distances are the same or different for the top and bottom bars. Using different distances helps in placing top and bottom hooks so that they do not collide, for example.

  • When defining the Spacing type on the Picture tab, you can now select to set the spacing by exact spacings. List the distances between the bars in the Spacing box.

Steel components


Base plate (1004) , Stiffened base plate (1014) , U.S. Base plate (1047) , Joining plates (14) , Stiffened end plate (27) , Partial stiff end plate (65) , Two sided end plate (142) , End plate (144)

It is now possible to create two new types of shim plates where the shim plate is created as two separate plates divided horizontally or vertically with the corresponding slots.

Tube crossing (22)

On the Brace conn tab, you can now define a gap between the gusset and the connection plates.

Tube gusset (20) , Tube crossing (22)

On the Brace conn tab, you can now to set the position of the middle end plate.

Shear Pl to tube column (47)

  • You can now define the bolt properties separately for the primary and secondary bolts.

  • You can now define the radius of the top and bottom beam cut on the Primary and Secondary tabs.

Purlin 1 (61)

On the Bolts tab, you can now select from the Slots in list the parts in which slotted holes are created.

Partial stiff end plate (65)

You can now define the distance between an L profile end and the top of the main part.

Railings (S77)

You can now define separate position and rotation settings for the top and bottom rails on the Rails tab and for the middle rails on the Middle Rails tab.

Bridging (80)

There are now 4 new bridging types available on the Parameters tab: Stratco , Safebridge , Metroll , and Steel and Tube.

End plate (101)

You can now align the end plate with the secondary part slope using the Adapt to secondary part slope option on the End plate tab.

Stub connection (119)

You can now set the thickness, material and name separately for the top, back and middle stiffeners on the Parts tab.

Full depth (184) , Column with stiffeners (186) , Column with stiffeners (188)

On the Plates tab, you can now select whether the shear tab is cut parallel to the main part web.

JP Full depth special (185)

You can now define the inner shear tab chamfers and the chamfer dimensions on the Plates tab.

Stiffeners (1003)

  • You can now rotate the stiffener polygons on the Parameters tab. You can set the rotation for both the right and the left stiffener.

  • You can now define the stiffener plate distance from the beam flange on the Picture tab.

Stiffened base plate (1014)

You can now select to create two grout holes on the Parameters tab.

Doubler plate (1022)

You can now use separate settings for horizontal and vertical welds.

Stiffeners (1034)

It is now possible to create a weld between the bottom flange of the main part and the stiffener plate using weld 2, and a weld between the top flange of the main part and the stiffener plate using weld 3.
