I have a Validation > Model > General > “Raised support provides lateral restraint” warning. Why do I get this and how do I resolve it?

Question I have a Validation > Model > General > “Raised support provides lateral restraint” warning. Why do I get this and how do I resolve it? Note. This is a new validation warning introduced in Tekla Structrual Designer 2018. Prior versions did not flag this issue to your attention. Answer A raised support is a support that occurs on a higher (raised) level than the lowest support in the model. A couple of situations where this warning can arise are listed below: Where we have multiple foundation levels in the model. Where we are trying to model support from an adjacent

Question I have a Validation > Model > Supports > “Support clashing with member length” warning. Why do I get this and how do I resolve it? Answer If we hover over one of the problem supports a tooltip is displayed “A support has been defined at a position other than the base of a column/wall - review model” We can double click the “Support clashing with member length” warning or an individual support listed under the branch to highlight the supports or support in the model. Alternatively, you can right click the item and choose Highlight Items from the context menu. The supports

I have a Validation > Model > General > “Invalid effective width” error. Why do I get this and how do I resolve it?

Question I have a Validation > Model > General > “Invalid effective width” error. Why do I get this and how do I resolve it? Answer In the screenshot below two beams have been identified as having an invalid effective width issue. Beam 1 is defined as a beam of Construction "Composite beam", however, the slab that is placed on the beam is not a slab of Type "Composite slab" and hence the error. The slab above the composite beam needs to be a composite slab so that the data of the two objects can interact together. Alternatively, the beam needs to be Construction "Non-composite

Question I have a Validation > Model > General > “Grid is not quite aligned with building directions” warning. Why do I get this and how do I resolve it?   Answer You specify the Building Directions for the model. These by default follow the global X and Y directions, but can be set via the Project Workspace > Structure window by selecting the Structure branch. See the linked article in the right pane for further information on Building directions.   The warning will result if a gridline is placed into the model which is less than 0.01 degrees out of alignment with the Building

I have a Validation > Analysis > General > “Material Poisson’s ratio is invalid for 2D elements (0 < v < 0.5)” error. Why do I get this and how do I resolve it?

Question I have a Validation > Analysis > General > “Material Poisson’s ratio is invalid for 2D elements (0 < v < 0.5)” error. Why do I get this and how do I resolve it? Answer 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 ratio of lateral strain to longitudinal strain in a material subjected to loading. The Poisson's ratio for a wide range of materials fall within a lower limit of -1.0 and an upper limit of +0.5. Since most common

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

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.

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?   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

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.

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
