The connection creates fastening plates on the beam(s), neoprene pads glued to the ribs of double tee beam, and the steel 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.
that is welded to fastening plates during erection of the building. The connection also creates round holes through the double tee beam ribs.
There is only one sided connection available. When two double tee beams are on the same concrete beam, the one sided connection shall be applied to both of them.
The connection is designed to work with standard double tee beam (parametric TT profile), precast element manufacturer Parma parametric TEKSLAB profile and precast element manufacturer Luja parametric SUPERTT profile.
The connection can be created from Component catalogcatalog that contains all system components and custom components, and the macros and applications
The term component catalog is used in Tekla Structures until version 21.1.
. The connection name is “Double tee beam connection”.
After starting the connection:
Select the beam part under the rib.
Select the double tee beam.
If the other rib is on top of different beam, you can select that as third input partpart that exists in a model and that the user selects when creating a component
Beam End Fitting
Normally the double tee beams end has a straight angle compared to the beam axis and there is no need to create the fitting.
Commonly the neoprene pad between the concrete beam and double tee beam rib is made of constant thickness plate.
Note: The vertical location of the bolt 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.
is depending on the manufacturer and also affected how the strands are located on the bottom of the rib. Contact the double tee beam manufacturer to decide the exact location of the bolt hole!
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.
attribute of the neoprene pad and erection plate are used only if the Class on the General tab is set into -1.
The bolt size is given by the double tee beam manufacturer. Also confirm the slotted hole dimensions and the bolt objects hole tolerance the manufacturer.
Before using this connection, make sure that you have imported the necessary fastening plate custom components in your model.
Usually the rib bottom is straight even when the double tee beams are sloped. If the building is under significant dynamic vibrating load due to machinery inside, the neoprene pads should have constant thickness and be horizontally positioned. For that you need to do the cuts in the bottom of the double tee beam yourself. However, the connection recognizes the cuts and positions the neoprene pads correctly also in this case.
