Tekla Structural Designer product bulletin August 2018 (PBTSD-1808-2)

Résumé of issue This issue relates to the design of steel beams and columns forming part of a seismic force resisting system (SFRS).  In the following specific circumstances, the required strength value used in the Seismic Strength checks is incorrect producing a potentially unconservative result: Head Code set to United States. Models for which non-linear analysis is required (typically, but not exclusively, those with tension only bracing). Beams and columns in all kinds of SFRS in which they are subject to seismic strength checks. Seismic Wizard Analysis Procedure set to ELF. The Design

Tekla Structural Designer product bulletin August 2018 (PBTSD-1808-1)

Résumé of Issue This applies to all Head Codes and relates to the checking of parts of a model following an analysis using the Structure Tree context menu check commands, such as ‘Check Plane’ and ‘Check sub structure’ etc.  For these commands no check was performed for steel members in the selected part and their design status was not updated.  It is possible the engineer could miss this and think a design had been performed.  Note that the context menu design options such as ‘Design Plane’ did function correctly. Occurrence This issue relates only to Tekla Structural Designer 2018 Service

I have a Validation > Model > General > "Member intersection" warning. What does this mean and how do I resolve it?

Question: I have a Validation > Model > General > Member intersection warning. What does this mean and how do I resolve it? Answer: The intersection warning means that the beam is not a two (or more) span continuous beam but rather a beam that will interact with the column (i.e. a column force may prop it up or drag it down depending on its behaviour). This can be appreciated through the load analysis view. This warning can be addressed or ignored depending on the desired behaviour; this is ultimately your decision. The warning can be addressed in three ways: The following

Is there a way to silently install Tekla Products?

What information do I need to be able to deploy silently? The Distribution Deployment document shipped with the installation details which components need to be installed and the order to install them, see How can I centrally deploy Tekla software? The only caveat is that the document is specifically written from an MSI Admin install perspective meaning that an Admin install is generated with the customers setup preferences defined and then this is is deployed. If you want to skip the Admin install and install the MSI Components using the command line then replace the documented switch /a,

When I attempt to play a video in Tekla Structural Designer Help, it states that Adobe Flash is required. I've installed Adobe Flash and the same message keeps appearing. How do I resolve it?

Question We are trying to run some of the video tutorials from within Tekla Structural Designer Help, but the content fails to display and there is the familiar "Get Adobe Flash player" message on-screen as below. We believe Adobe Flash is installed, as the videos all run perfectly from within the chosen browser, normally Internet Explorer via Tekla User Assistance > Videos. Is there a way to get the Tekla Structural Designer Help system to see that Flash is actually installed? Answer Tekla Structural Designer Help uses Adobe Air. This requires the Opera/Chromium version of the Flash

Control and manipulate Design Groups

Question: How do I control and manipulate design groups? Answer: To allow for a quick and efficient design process, all concrete beams and columns (not walls) are automatically placed into Design Groups. The following example will take a look at how Design Groups are formed, the design procedure for a Design Group and how to design individual groups. How are design groups formed? Design Groups have no specific engineering data associated with them and are simply a unique name for a collection of similar frame elements. Various criteria are used to determine which group a particular element

What properties should I use for analysis elements?

Answer The answer depends on why you are using them and what you are trying to achieve.  Two common scenarios are discussed; For Wind Wall spanning. For ‘rigid’ elements for structural offsets/ connectors/ ‘battened’ members General Recommendations Whatever the reason for using analysis elements, some general principles to follow can be stated : Do not just accept the default property values as these are very small and entirely arbitrary.  We advise that engineers always make a rational choice of suitable values and enter these. Avoid using infinitesimally small or astronomically large

Shear wall analysis - New modelling, same answers

Engineers now routinely have access to highly capable 3D analysis packages often including the ability to use finite elements (FE shell elements). More and more structures are being analysed in 3D, and as suppliers of such software we are certainly being faced with increasingly frequently asked questions relating to the modelling of shear and core wall systems using shell elements within the context of a 3D model. Please note this is an historical article that has been uploaded without modifications from the old CSC Knowledge base.

Geometrical limits for Web openings in Non-composite beams (Eurocode)

Introduction This article will look at the geometrical requirements when specifying web openings in non-composite beams to the Eurocode. Web openings can only be defined within a beam once a section size has been specified. This is achieved by either specifying the section size to check, or by running an initial Automatic design and then adding the web openings to the proposed section via the Web openings page of the Edit member dialog (right click beam and Edit…) once the Automatic design option is unchecked. It is worth noting that if you use the Quick layout option and Add openings then

Can we check an allowable bearing pressure against serviceability loads in Tekla Structural Designer?

Question We often receive Soil Investigation Reports with allowable bearing pressures for use with pad / strip footing design which can be used in accordance with BS EN 1997 CL 2.5 "Design by prescriptive measures". This capability is available in Tekla Tedds, where the allowable bearing pressure is checked against the SLS Loads applied. Is a similar option available within Tekla Structural Designer as it would appear it will only check bearing capacity based upon the ULS design bearing pressure against the net ultimate bearing capacity?

Question I have a Validation > Model > Slab/Mats > “Foundation mat with ground bearing springs not meshed” warning. Why do I get this and how do I resolve it? . Answer When you define a mat foundation using the Foundations ribbon tab > Mats group you can define the Soil Parameters including the Use ground bearing springs option within the Properties window. With this option checked the mat is supported on ground bearing springs located at the analysis mesh nodes to model the soil interaction under the foundation. This is achieved in the underlying solver model by including the

I have a Validation > Analysis > General > “Settlement loads applied in unfixed direction” error. Why do I get this and how do I resolve it?

Question I have a Validation > Analysis > General > “Settlement loads applied in unfixed direction” error. Why do I get this and how do I resolve it? Answer Before we look at the Settlement loads validation error let us consider a support in more detail. A support can have 6 degrees of freedom, Translational Fx, Fy, Fz and Rotational Mx, My, Mz. Each degree of freedom (DOF) can be either Fixed or Free. When a degree of freedom is set as Free, it can either be Released or act as a Linear or Non-linear spring. If you set the support as a spring then you define the Stiffness to be

How do I apply rotational base fixity to a column?

Rotational base fixity can be assigned to the support under a column via the Properties window. For the selected support the translational and rotational degrees of freedom can be assigned. These can be Fixed or Free. If Free then a stiffness can be assigned as either Release, Spring Linear, Spring Non-linear, Nominally Pinned or Nominally Fixed. Before we assign a stiffness, however, it is crucial that we understand the local coordinate system for the column and support. The Help system provides an explanation for the special case for 1D members and a general case for 1D members. We will
