Tutorial Etabs

[Kanisha Marchant]

Forthis section of the tutorial, we shall use the default Revit Structural Model File that we all know and love. We shall expose the Analytical Model Framing by opening up the viewer and toggling the analytical elements to be shown.

Now, go to the PlugIn tab, and press the ETABS connector plugin. If the plugin is not loaded properly; add the plugin at the current file location for ETABS18 or 19 respectively: "%LocalAppData%\Computers and Structures\ETABS 18\Speckle2ETABS" The Speckle Desktop UI2 should appear.

Currently there's some problem with importing section profiles due to unit conversions and limitations with the RevitAPI. However the name is passed so you can change the section profiles as needed in ETABS.

Let's create a new ETABS project using the default steel deck template that is offered in ETABS. You can use your preferred units, and code section. A project will be created with x default levels. The ETABS model labeled" " file in the drive has some default properties and imported sections as well as braced frames.

This concludes our setup. We'll now switch to Revit to receive it and use it to generate new ETABS elements. Check out the elements in the following embedded viewer. The stream is linked here. Note that I'm using Canadian Steel sections in this example.

Now let's open up an empty Revit project with our sections loaded in and the respective families needed. If there is a match that can be found, then it will map the properties to the family. If not it will go with the first default. Click the recieve button for the stream to recieve our newly generated data from ETABS.

Since Revit generates and need assignments to floor, a known issue is that if you do not have the corresponding loaded floors, Speckle will attempt to generate a floor for that element which may or may not result in unwanted modelling differences.

This document provides a tutorial for modeling and analyzing a G+10 reinforced concrete building using the structural analysis software ETABS. It outlines the step-by-step process for creating an ETABS model, including defining materials, sections, geometry, loads, supports, and running the analysis. It also describes how to display and interpret the results tabularly and graphically. The tutorial uses the architectural plans and specifications of the example G+10 building to demonstrate modeling the building, assigning properties, meshing, applying loads, and checking the model before running the analysis in ETABS.Read less

ETABS is the abbreviation of " Extended3D Analysis of building System". ETABSis a product of Computers and Structures, Inc. which is recognized globally as the pioneering leader in structural engineering analysis and design software for structural and earthquake engineering. They have introduced ETABS whith the following paragraph.

To use this powerful analysis and design package properly, one must learn it properly and practice a lot. Here we have gathered some tutorials available in the web. If you want to learn ETABS you can watch and learn from the following tutorials.

Computers and Structures, Inc. is the owner of ETABS software. To make the software fimilar with the structural engineers they have provided 27 tutorial videos. We suggest to start learning ETABS with these tutorials first.

Check out our dedicated tutorial on how to get started with CSI Products (opens new window)! The following shows examples of ETABS and the relationship between ETABS and Speckle but can be extrapolated to relationships with the other CSI connectors.

If the plugin is not installed properly, you can find the path to the PlugIn in the relative path here : This is the example for SAP2000, but you will see similar install folders to other paths in here.

To help you select which elements will be to sent to Speckle, we've built various filters into our CSI Connector. Once a filter is set, just click Send and all objects passing the filter will be sent to your Project. Section properties and materials defined within the model will always be sent.

The category filter lets you select one or more of the currently-supported CSI categories, this is the most granular filter that will also enable you to send results. Note : Other filters will not enable you to send results or non-geometrical elements and properties.

You can send analysis results from ETABS, and the connector offers a set of filters that allow you to share either all or only a portion of the results. All filters are multiple choice for flexible and granular control:

AnalyticalResults object is attached to an element and contains a list of resultsByLoadCombination which are representations of the analytical results that correspond to the different load cases / combinations that a user wants to send.

The connector does not take care of updating existing elements within the Project. However the CSI products does recognize if coincident elements are generated and will not generate new elements that coincide on top of each other.

When sending from elements from Revit, Speckle takes care of converting the data to a Speckle friendly format. If you're curious about how this data is being structured, please have a look at our Objects kit class definitions (opens new window).

To send elements from Revit specificially into a structural model, use the analytical models generated within a revit model. Currently there is no conversion from the BuiltElement object kits and the Structural object kits, which means that only the analytical models in Revit are supported to be converted into CSI. Give us feedback on this workflow.

The schema for the structural objects is based around our structural pyramid of objects. Refer to the discourse post (opens new window) here if you haven't for all the information about this kit. There are CSI application specific grasshopper components. Check them out and use them to build specific properties like deck sections. If there is no specific CSI component, use the general structural schema to define them.

Building models parametrically in grasshopper with the structural object schema is supported with CSI. To build section profiles from catalogue and have material definitions imported into the CSI from scratch, you will have to match the spelling of the catalogue directly as if you were importing it. Look below for an example of the spelling used.

To easily explore on object's data and parameters, our Speckle Web App interface can be of great help, as well as any other applications that lets you explore the object metadata (eg Grasshopper, Dynamo, Unity, etc).
