A key strength of Robot is the possibility to define a wide range of analysis types (linear static, non-linear geometry and material, buckling, modal analysis, harmonic analysis, seismic analysis, time history analysis etc.) If the user wishes to see these possibilities, he/she may look in the Analys�s > Analys�s types > change analys�s type pull down menu.

A useful feature is that only “selected” structure data in Revit® Structure is transferred to Robot – this allows only part of the model to be transferred to Robot (it could be useful if the user wants to select only part of a structure to analyze).

However, in this example, we want Robot to analyze all of the Revit® Structure data so it is important to ensure that either no data is selected or alternatively all of the structure is selected.

There are 2 ways to send data to Robot:

dynamic – send model to Autodesk Robot structural Analys�s –this is a dymanic trans-fer of data between programsby file – use Autodesk Robot structural Analys�s Rtd file – useful if, for example, Revit® Structure and Robot are on different computers

13�EXPORT REVIT MODEL TO ROBOT | Sending data to Robot


integrat�on w�th Robot structural Analys�s – send opt�ons dialog box allows you to configure export parameters

bas�c op�tons tab:

scope and correct�on group – enables the user to:Send entire Revit project (ignore current selection) - sends whole model (this option is selected by default – it prevents exporting of an accidentally selected element or elements.Send current selection only - sends only selected elementsExecute model correction in Robot - decides whether to run “draw-ing model correction” in Robot automatically, which will serve to join nodes to gether that fall within a certain tolerance

spec�fy the case that conta�ns self-we�ght - option allows for defining which load case will be considered in RSA as a self-weight case

If the first option is chosen, then User is able to specify Revit load case, which will be used in RSA for definition of self-weight. All loads defined in this case remain unchanged – self-weight will be added. It is possible to ignore definition of self-weight with using Revit load cases – by choosing second option.

bar end releases group - allows the user to select the way of handling end releases:

Do not use Revit settings (assign end releases in Robot) – end releas-es are manually defined in Robot.Use Revit settings – recognizes and assigns bar end releases defined in Revit® StructureChange Pinned-Pinned to Fixed-Fixed – all Pinned-Pinned end re-leases defined in Revit® Structure are changed to Fixed-Fixed. This is often set to avoid mechanisms in the structural model

INFO



integrat�on w�th Robot structural Analys�s – send opt�ons dialog box allows you to configure export parameters

Add�t�onal op�tons tab:

mater�als group - allows you to select the way of handling materials:Use Robot default materials – for each element’s material type (steel, concrete, timber) Robot will assign material from Robot database with standard properties Define new materials in Robot – creates new materials in Robot with such physical properties as defined in Revit® StructureSelect material of the best matching parameters - assigns material properties from Robot data base with the nearest values to those defined in Revit® Structure

curta�n walls - option allows for setting sending parameters for Curtain walls. Panels created in RSA have a property (triangular method of load distribution in panel calculation model is set), which allows load distribu-tion to other elements.

Analytical model only (no system panels, no mullions) – creates one panel in RSA without interior elements (system panels and mullions) – differences in singular panels are neglectedAnalytical model and mullions (no system panels) – creates one panel in RSA (no division to system panels) but also mullions are transferred – differences in singular panels are neglectedSystem panels and mullions (detailed model) – sends all interior ele-ments – system panels and mullions are created in RSA – differences in singular panels are considered

transfer (opt�onally) – set of additional options of sendingUse drawing model offsets as analytical – an offset parameter is defined for bar elements in RSA according to Revit’s definition Reinforcement projects (beams, columns, spread footings) – defined reinforcement in listed elements is transferred to concrete design modules in RSASteel connections – option not available in current version

A key strength of Robot is the possibility to define a wide range of analysis types (linear static, non-linear geometry and material, buckling, modal analysis, harmonic analysis, seismic analysis, time history analysis etc.) If the user wishes to see these possibilities, he/she may look in the Analy-s�s > Analys�s types > change analys�s type pull down menu.

However, for this simple example, we will just assume the default linear static type of analysis.
