I have a Validation > Analysis > First-order linear > “Non-linear elements changed to linear”” warning. Why do I get this and how do I resolve it?

Question I have a Validation > Analysis > First-order linear > “Non-linear elements changed to linear” warning. Why do I get this and how do I resolve it? Answer “Non-linear elements changed to linear”, indicates that elements have been defined in the model as non-linear i.e. able to withstand either tension or compression only, (which requires non-linear analysis) but a linear analysis has been undertaken. Linear analysis cannot cater for non-linear behaviour, and so non-linear elements are converted to linear elements to allow a solution. It is likely the analysis results would

When I include a saved view in the report it is too small. Can I make the image bigger?

Question When I include a saved view in the report it is too small. Can I make the image bigger?      Answer There a few things that can be done to improve the size of the image (saved view) included within the report. We will run through a number of options, however, some will have a more profound effect than others. By default the image is set to be 90% of the page width. You could increase this percentage to widen the picture. This can be achieved via the Report ribbon tab > Appearance group > Settings > Document Options page.        You could change the orientation of the

I have a Solver > Model > Analysis Properties > “Invalid Material Properties - Poisson’s ratio is X.XXX” error. Why do I get this and how do I resolve it?

Question I have a Solver > Model > Analysis Properties > “Invalid Material Properties - Poisson’s ratio is X.XXX” error. Why do I get this and how do I resolve it?   Answer Background The Material database contains the concrete grade properties when the chosen material is used in the model. In the screenshot below, the Modulus of elasticity, E is specified as 34000 N/mm2 for C32/40 concrete.    Tekla Structural Designer uses the theory of isotropic linear elasticity so the modulus of elasticity, E is related to the shear modulus, G by way of Poisson's ratio, v. Poisson’s ratio is the

I have a Validation > Analysis > General > Supports > "No supports defined in model" validation error. Why do I get this and how do I resolve it?

Question I have a Validation > Analysis > General > Supports  > "No supports defined in model" validation error. Why do I get this and how do I resolve it?   Answer This message is self explanatory. No supports exist in the model (i.e. under columns), and hence the structure is unsupported. Applied loads cannot go to ground and hence the structure is not in equilibrium. We have seen this appear after a mat foundation has been modelled. In this scenario, the supports that are automatically placed under columns are manually deleted to ensure the columns are supported on the mat

When I review the Project Workspace > Status window I can see a validation warning "Validation is outdated". Why do I get this and how can I resolve it?

When I review the Project Workspace > Status window I can see a validation warning "Validation is outdated". Why do I get this and how can I resolve it?   This validation warning can appear under the Validation, Model, Analysis and Design sub-branches. Typically you will see this message if you make edits to the model file or invalidate an analysis or design in some way. There is a dependency that before any analysis and/or design can be performed Model validation must be completed. Before an Analysis, both Model and Analysis validation must be completed and finally before a Design -

Is it possible to reverse the direction of a concrete beam detail drawing?

Question I am trying to generate a concrete beam detail drawing but would like the generated drawing to detail the beam in the opposite direction. Is it possible to reverse the direction the beam is detailed in? Answer Entities in Tekla Structural Designer have a span direction. You can see this by turning on the Scene Content > Members > Direction option. An arrow is drawn on top of the entity to denote the direction of the member. In the screenshot below the entity arrow goes from gridline 1-2-3.   When you generate a detailed drawing it is always laid out on the DXF from left to

I have a Validation > Model > Load > "Area load not defined within a panel area" warning. Why do I get this and how do I resolve it?

This validation warning can appear when a command from the Load ribbon tab > Panel loads group is applied to the model but the load is not wholly contained within the slab boundary.   It is most common when applying Point load, Line load, Patch load, Polygon load or Variable patch loads.   You can locate the problem load by double clicking on the reference in the Model > Validation > Loads > Area load not defined within a panel area branch of the Status window. This will display the load in the active view - if it exists, or switch to the 3D Structural view and highlight the

I have a Validation > Model > General > "Member intersection" error. How do I resolve it?

A Member intersection is a model validation error that can occur if two members have crossing centrelines. A member could be a beam, column or brace. In the example below we are looking at a beam, however, the resolution is the same regardless of the member type. In the screenshot below, the Status window is reporting two members with an intersection issue. SB 1/~15-1/1/'29 : SB 1/A/2-1/B/2 Double clicking this branch highlights both members in the active Scene view.   Double clicking the individual members listed under this branch highlights each in turn.

I have a Validation > Model > General > "Member collision" error. How do I resolve it?

A Member collision is a model validation error that can occur if two members have a common length in which their centerlines clash. In the screenshot below, the Status window is reporting two members colliding. SB 1/A/1-1/B/1 : SB 1/A/1-1/1/'29 Double clicking this branch highlights both members in the active Scene view.   Double clicking the individual members listed under this branch highlights each in turn. This perhaps provides a little more detail on the issue. One member extends between the columns while the other member only extends for part of the length. Both, however, have a common

Validation

What is Validation? Validation is an integral part of Tekla Structural Designer as it ensures a valid model is presented for the analysis and design routines. In Tekla Structural Designer validation is broken into three separate validation categories: Model Analysis Design Model validation includes any model integrity checks, that entities are connected and supported correctly, and that loads are applied correctly. Analysis validation ensures the analysis model (known as the solver model) is valid to run through the solver. Design validation ensures that a valid design can be

I have a Validation Warning > Model > General - "Member may not be supported as intended". How do I resolve it?

Issue Tekla Structural Designer will flag elements that may not be supported as you intend. Whilst this is a Warning rather than an error it can have design implications and could also cause problems with analysis. We recommend that this error is never ignored and that the engineer review their model to ensure that both the connectively and design model are as they intend. All members with the issue will be flagged with a warning message in the Validation Status Tree as shown below.   Resolution and Examples In all cases, double click the warning and the problem members will be highlighted

Building Directions

Question When applying Equivalent horizontal forces (EHF’s) or reviewing Analysis or Tabular results such as Deflections, Storey Shear or EHF’s there are references to Dir 1 and Dir 2. What are these?         Answer In Tekla Structural Designer buildings are set out in the Global X, Y and Z co-ordinates. For the majority of models you would probably model the building such that the “principal axis” of the building aligns with the global X and Y directions as the screenshot below.   A building may however, have its "principal axes" oriented at any angle to the global axes (in plan).   There

Tekla Structural Designer product bulletin Mar 2018 (PBTSD-1803-2)

Résumé of Issue This issue relates to the properties of plated sections created using US Customary units, hence only the US Head code is likely to be affected.  For US Customary units, some plate dimensions were stored with insufficient precision resulting in a loss of accuracy for plated section properties.  We would note that  in general the issue affected principally analysis, as design for plated sections was not carried out in previous releases for the US Head code.  Additionally, since plated sections and their plates are more commonly large (in which case the lower precision would have

Tekla Structural Designer product bulletin March 2018 (PBTSD-1803-1)

Résumé of Issue This issue relates to the design of steel braces for the BS Headcode (All Countries).  For braces subject to tension using double-angle sections, the tension capacity check used the gross area Ag of the brace, rather than the net area Ae, potentially producing an unconservative design result. Occurrence This issue relates to  Tekla Structural Designer 2017i (version 17.1.0.64 released in Sept 2017) and subsequent releases.* *The previous Product Bulletin on this topic PBTSD-1801-3 was incorrect in this regard.

Is it possible to save a customised Scene View?

Question If I close an open scene view and re-open it, I find that I lose any scene content settings that I have defined and need to set them again each time. Is it possible for the scene view to remember the settings? Answer Yes, you can use Save View Configuration…. You can open scene views to display the model as either a 3D Structure, a specific level, frame, inclined plane, sub model, sub structures or individual member view. You can also use the Cutting Planes command to reduce a 3D Structure view by cutting planes from any face of a cube. How to create these views is not the topic of
