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

Is it possible to add or amend the ratio divisions used when viewing a Ratio command on the Review ribbon?

Question When viewing one of the Ratio commands on the Review ribbon, we would like to add our own divisions or adjust the existing ones to better interogate the model. Is this possible?   Answer Tekla Structural Designer 2018 has added the ability to add up to a maximum of 10 user defined divisions along with a user defined colour for each. These can be specified via the Home ribbon > Settings > Scene > Utilization Ratios page. The default values are shown below.   In the screenshot below we have input the maximum 10 divisions by clicking Add, setting the Minimum value required,

Insufficient stress block

When designing a base plates subject to moment, in order to develop the rotation and potential resistance in the tension bolt group, we need to provide a reasonable compression zone between the extreme edge of the stiff baseplate cantilever length ‘c’ and the concrete grouting compound.  The design model always assumes there is a (compression) stress block and cannot consider moment without one. The minimum length of compression stress block has been set as 10 mm.  Small design forces For the situation of relatively small loads (relative to size of connection) and axial + small moment the

How the shear P_{ss} is calculated for adjustable bolts in a column base connection

To calculate the shear force applied on the bolts the average shear stress is multiplied by the area in shear. Please see the diagram below which represents the area in shear. If the bolt is set as being non-adjustable, Column Base will use 6d2fcu (See Green Book Page 97) to calculate the bolt bearing on concrete. If you have set your bolt in grout which is a strong as the concrete the same formula can be used. When applying this to an adjustable bolt, the factors set in Column Base will use the factors which the user applies, the Column Base defaults for both factor are set to 1, therefore

Wind Loads beyond scope for multi-span frame with roof slope less than 5 degrees

According to BS6399-2, rafters slopes less than 5 degrees should be treated a flat. For a single standard span Tekla Portal Frame Designer will apply the adjacent, intermediate and remote coefficients assuming a single flat roof. For multiple spans it will not. You need to calculate the coefficients & their lengths and apply them manually. As the scaling length is likely to be based on the eaves height, you could create a single span frame (does not need to be the full width of the building) and generate the wind loads cases to obtain this information. In the main model, the first frame

What is the difference between ULS Wind and SLS Wind?

ULS Wind uses coefficients from BS6399:2 Table 5 and should be used for all strength checks.SLS Wind uses coefficients from BS6399:2 Table 5A and can be used for serviceability checks. If you wish to use SLS wind (Table 5A) you should create a combination with ULS wind and select to perform just ULS checks, then create a matching combination with SLS wind and select to perform just SLS checks. Below is a suggested order of the steps to take to resolve problems with deflection under wind - note at any point you may decide to change you section sizes etc: ULS WindULS Wind + SLS Base FixityULS

Why do SCI P292 and Amplified Moments Method Frame Stability Checks fail?

For certain frame configurations these checks can be shown as Fail on the Design Summary because the elastic critical load factor is shown as 0.000. This will occur when there is the unusual situation where a member is changing from being in tension to compression along its length. The program traps this situation out because the calculation would otherwise have to assume the member in one state or the other along its entire length, which would mean the answer could be either too conservative or too unconservative. To check if this is the problem simply examine the axial force diagram for the

How do I model a nominally rigid base in Tekla Portal Frame Designer?

Nominally rigid bases should be modelled in accordance with clause 5.1.3.2 of BS5950-1:2000 which states"If a column is rigidly connected to a suitable foundation, the following recommendations should be adopted:a) In elastic global analysis the stiffness of the base should be taken as equal to the stiffness of the column for all ultimate limit state calculations. However in determining deflections under serviceability loads, a base may be treated as rigid.b) In plastic global analysis any base moment capacity between zero and the plastic moment capacity of the column may be assumed, provided
