Tekla Structural Designer product bulletin January 2020 (PBTSD-2001-2)

Résumé of issue This issue relates to the analysis results for some steel members using Angle sections for all Head Codes.  Analysis results could be incorrect for steel members only in the following very specific circumstances: The member section was a single angle. The member characteristic was one of the following; Column, Gable Post or Parapet Post. When the member was not set to be "continuously restrained" We expect that these conditions existed in very few models and, even in the unusual case where it did apply the overall effect was likely to be negligible.

What is the "Prevent out of plane instability" factor for and when would I use it?

Answer Briefly, the setting is for use when buckling is causing solution problems in 2nd Order Analysis.  For more about 2nd Order Analysis see the related article What are the "2nd Order" Analysis options on the Analyze Ribbon in TSD? An example of when such buckling problems might occur is in members subject to axial loads which are relatively slender about the minor axis - such as sloping rafters - where secondary members (such as purlins or rails) which would reduce the buckling length are not included in a model.  For the full context of when you would usually use this setting, see the

What is 2nd Order Buckling Analysis? How and when would I use it?

Background For the full context of when you would usually use 2nd Order Buckling Analysis, see the Related Article I have analysis Warnings and/ or Errors about buckling. Why is this happening and what do I do about it? Buckling is a regular, everyday phenomenon with which everyone - including non-engineers - will be familiar, as illustrated in the picture below of a buckled plastic ruler.  Depending on the analysis type being used, buckling can also occur in computer analysis, just as in reality, if members are insufficiently stiff to resist the compressive forces applied to them. In TSD,

What are the "2nd Order" Analysis options listed on the Analyze Ribbon in TSD? Are they the same as "P-Delta" analysis?

Answer For an explanation of 2nd Order analysis and effects in general, please see the attached article A brief overview of 2nd Order (or P-Delta) Analysis. (A version of this article was published in the Jan 2003 edition of the New Steel Construction magazine). TSD has both Linear and Non-linear 2nd Order analysis options.  Both types will give both P-"BIG" delta (P-Δ) and P-"little" delta (P-δ) effects (for both 1D and 2D elements), as described in the attached article and illustrated in the diagrams below.  As such they may also be termed "P-Delta" analysis.  However, as the attached

Using Revit with Tekla Structural Designer - Guidance Notes

Overview Attached is the document Tekla Structural Designer Integrator - Revit Guidance.pdf These guidance notes have been developed to give practical advice to users of Autodesk Revit wishing to integrate models between Autodesk Revit and our own Tekla Structural Designer software. This document largely deals with the subjects of model connectivity and object mapping as these are the most important considerations when building models within Autodesk Revit. Several sections relating to important information and advanced subjects are also contained.

Tekla Structural Designer product bulletin November 2019 (PBTSD-1911-1), Tekla Portal Frame Designer product bulletin November 2019 (PBTPFD-1911-1)

Résumé of Issue This issue relates to integration of Tekla Structural Designer (TSD) & Tekla Portal Frame Designer (TPFD) for the BS and Eurocode Head Code.  In some circumstances loads on a Portal Frame in Structural Designer were not correctly exported to Portal Frame Designer.  Loads could be duplicated and/ or act in the opposite direction, which could result in design forces being either increased or reduced depending on a number of factors.  Where the issue occurred it would usually be apparent from markedly different forces and deflections in Portal Frame Designer compared to those

I have a Validation > Model > General > “Panel is not surrounded by load carrying members” error. Why do I get this and how do I resolve it?

Question I have a Validation > Analysis > Model > “Panel is not surrounded by load carrying members” error. Why do I get this and how do I resolve it?   Answer The issue here is that the two types of panels are not correctly spanning onto the supporting members. As a result, load distribution cannot be carried out for the one way spanning panels. This issue can affect wind walls, roof panels and one way spanning slabs of all types. The issues usually stems from 3 problems which are as follows: Panel is not correctly spanning onto/does not meet the supporting members Supporting

Tekla Structural Designer product bulletin October 2019 (PBTSD-1910-1)

Résumé of issue This issue relates to the design of Pile Caps to the Eurocode (All Country NA’s).  For the shear check and the reduced design shear load near to supports per EN 1992-1-1 Cl. 6.2.2(6), the lower limit of  av = 0.5d for checks undertaken at av ≤ 0.5d was not applied which could result in an unconservative design result. Occurrence This issue relates to Tekla Structural Designer 2016i (version 16.1.0.78 released in Sept 2016) and subsequent releases.

Why are my columns bigger than they are supposed to be on plan?

Question: I have exported my GA to a DXF file, when I import that DXF file into another project to the same scale, my columns appear bigger than the imported drawings, why are my columns bigger? Answer: By default in Tekla Structural Designer, there is a setting found in Home > Settings > Scene which doubles the size of the columns. This is a tick box which can be unticked if you wish to have the columns drawn to scale. The setting is found in the Settings window under Scene > View Settings as shown below.   Note: You may need to redraw the view for the settings to take effect

How can I connect to a license server?

Assigning a server during installation: A license server is intended to be assigned during the installation of a product. The user is asked to select a license method during the installation process (server in this case), then asked to type either the name (hostname) of the server or the IP address of the server. When the installation is complete and the product is launched, the product will use the server method and server name assigned during the installation to claim a license.   Assigning a server after installation: This is one of the most frequently submitted queries to Tekla Support

I have a Validation > Model > Concrete Cores > “Rigid section behaviour is not guaranteed due to uncoupled members” warning. Why do I get this and how do I resolve it?

Question I have a Validation > Model > Concrete Cores > “Rigid section behaviour is not guaranteed due to uncoupled members” warning. Why do I get this and how do I resolve it? Background Cores in Tekla Structural Designer can create single entities out of mixed groups of Concrete Walls (designated as Meshed and Mid-pier), Concrete Columns and Concrete Beams, which for the main purpose of this feature are expected to act monolithically. This monolithic behaviour however,  is not enforced by the creation of a Core, and validation has been put in place to assist in highlighting cases
