How do I assign a wall as a Shear wall and not a bearing wall, when importing from Revit into Tekla Structural Designer?

When generating a Revit model the Structural Usage property defines the type of wall. The default is Bearing which when exported to Tekla Structural Designer exports the wall as a bearing wall. If you wish to export the wall as a Shear wall then change the Structural Usage property to Shear within Autodesk Revit prior to exporting.

Where do the default values for cracked and uncracked properties of concrete come from?

Question Where do the default values for cracked and uncracked properties of concrete come from? Answer 1. Modification Factors Analyse ribbon > Options > Modification Factors > Concrete allows you to define the factors for use in the different analysis types performed.   These factors are applied to the various element types, based on whether the section is specified as cracked or not in their member properties. The factors reduce the full short term stiffnesses of the members to their long term values, which allows for long term effects, such as creep, cracking and shrinkage, and

I have a model that has both column and matt foundation support reactions. How do I turn off the Matt foundation reactions to declutter the Results view?

Question Currently, the Results View > Support Reactions group controls the display for all support types (Column, Walls, Matt foundations etc.), so everything is either On or Off in the scene view being displayed. There are currently no Scene Content controls to further refine the display.   So, how do we turn off the Matt foundation reactions to declutter the Results view? Answer Sub Structures The solution is to create a scene view that only has the items you wish to view results for. You can achieve this by using the Sub Structure command within Tekla Structural Designer. Use the

When should I use the "Mesh 2-way Slabs in 3D analysis" option?

Introduction In Tekla Structural Designer you have the option to mesh 2-way slabs in the 3D analysis.  As a default this option is not selected and typically we do not encourage it. So the discussion here is about: When should slabs be meshed in 3D? Since it is possible why would you not just do it all the time? Traditional Structural Idealisation Structural engineers have not traditionally created large FE models of entire buildings, the ability to do this is a relatively recent phenomenon. Traditionally engineers analysed one floor at a time, or even one continuous beam at a time.  This

I have validated the model but it is showing "?", saying validation has not yet been performed. Why?

This is to be expected. You will need to click on the + symbol to the left of the ? mark in order to expand the validation branch of the tree. (Clicking the - symbol contracts the branch). You will see that there are three types of validation Model, (which is undertaken when you press the validation button) and then Analysis, and Design   2 and 3 are only undertaken when you perform an analysis and design process.   If we perform a design, (which performs both an analysis and design), then you will see that you will obtain ticks or crosses against the analysis and design that have been

Is there a way to stop the Solver/Design running while it’s solving?

Question Is there a way to stop the solver running while it’s going? I’ve noticed that if I try to run a model which, whilst valid according to Tekla Structural Designer, has some “overly-pinned” members that the solver takes hours to run through, as it calculates parts of the structure deflecting off to infinity. Answer During an Analysis/Design process a Cancel button will appear in the bottom left of the taskbar next to Show Process. Press this button to stop the analysis/design.   We recommend that you run the analysis method of choice via the Analyse ribbon for just the self weight and

Where can I find the Autosave file in Tekla Structural Designer?

Autosave is only used whilst you are in the software to protect against unforeseen issues whilst using the program. The Autosave feature is controlled via the Home ribbon >Settings group > Settings command   In the unlikely event that the software crashes whilst in use, upon re-starting the program it will identify if an Autosave exists and offer to recover it. This Autosave file/location can be determined via the registry (Start > Type "Regedit". Note you may require administration rights) and will relate to the version of the software you have installed. You can determine the

How do I define an element in the model with zero density?

When using wall panels that span vertically, an element is required at the base of the structure to pick up the load decomposition. You may wish to place elements in the model that do not add weight to the overall structure. Create a General Material Property with zero density Click Home > Material. Open the Material page Set the Material type to General Click Add Define an appropriate property but with zero density.   Place an analysis element at the base of the wall ensuring you assign the material grade defined above Ensure Characteristic is Analysis element Ensure Material type is

Why will the analysis not complete when my model only has tension only bracing?

Problem In some rare problematic models/ loading situations, where most or all braces may experience compression and become inactive, can cause instability. This can prevent an analysis solution from being found. Resolution Tekla Structural Designer 2017 has introduced Relaxation factors, as a means of resolving this issue. Relaxation factors control an amount of nominal compression, that tension-only braces can undergo while remaining active during analysis iteration. When converged, these tension-only braces will still have only either zero or tension force. The process is entirely

Why am I unable to change the Overall depth property of a Precast slab?

Problem The overall depth is greyed out. How do I amend it to specify the thickness of the precast deck I want to use? The program will not allow you to set the depth of the precast deck using the overall depth property, you will see that this is greyed out for precast planks.   Resolution You will need to define the Decking properties > Manufacturer and Reference. You will then be able to set the Gauge. If required, you can also define a Topping. The Overall depth is then automatically calculated as the gauge depth and topping depth.     Note: There are only a few default Precast

Why does the effective width of composite beams not calculate automatically when the decking is parallel?

Example Issue Take the example below, where the beams are parallel to each other but have different beam lengths. What effective width should be taken in the area where the width of the slab tapers?   Tekla Structural Designer is able to calculate the effective width, provided the beams are parallel, or thereabouts, and of similar lengths. You can control this tolerance on rectilinearity via the Design ribbon tab > Options > Composite Beams. The default value is 15 degrees (90-67.34 in the example above) and if this is exceeded, the program will not calculate the effective width

How can I determine the maximum overall displacement in my model?

Introduction Tekla Structural Designer 2016 and above will provide details of the maximum positive and negative nodal displacements in the model. The Project Workspace > Status pane, Design > Overall Displacement branch, reports the displacement values for the node and load case/combination reported in the description. i.e. Service factors, Positive direction - X direction, Load combination 11, Node 93   These are solver nodes so will also include nodes at the midpoint of elements (known as "pdelta" nodes). You will not see these pdelta nodes in the deflection diagram, since the

How do I check for Wind Drift?

Introduction Tekla Structural Designer 2016i has added a wind drift feature to the software. Wind drift checks are performed on both steel and concrete column stacks. A stack is defined as the length between floors. They are only performed on wind load cases as well as to service combinations that contain wind. In any other load combination this check is not performed.   How do I turn Wind Drift checks On/Off? The Wind Drift check is a property of the individual column. This provides the ability to turn the check for specific columns On/Off, if required for the whole column or individual

Why are wall wind zones reported as Zero when I review the Zone Loads for wind load cases?

Issue Why are my wall wind zones reported as Zero?   Resolution In the screenshot below, the Load ribbon > Wind Load group > Wind Wizard... command has defined the Ground level as  -0.5m. Wind is ignored below this value.   If we review the Model ribbon > Levels group > Construction Levels command, the levels in the screenshot below are between -6m and 0m.   The wind load is only applied beginning at the height of -0.5m as defined in the Wind Wizard. Hence, the Zero locations are where the model falls below the Ground level of -0.5m where wind is ignored.

How do I delete a grid or construction line?

In this article you will learn how to delete a gridline in Tekla Structural Designer Problem When you select the grid or construction line and press the Delete command on the quick access toolbar the "Entities to be deleted" dialog box is empty. Why?   Resolution You can only delete a grid or construction line if it is not being referenced by any other element, load, dimension etc. , or a Frame does not exist that utilises the gridline. Architectural grids are shared and therefore exist on all the levels specified for the grid system. As an example, a beam exists on an upper level that
