    Truss Roof – Joint Force Imbalance Due to TRP Plate Modeling

    Can you post some screen shots of what you are dealing with? Maybe some quick math for the unbalance that you are seeing as well? Does the unbalance "balance" out with section cuts through both the truss and the TRP sheet? In general, even though a "low" in plane stiffness modifier has been...

    ETABS API - Extract internal joint displacement

    This code did the trick for me: x = SapModel.Results.Setup.DeselectAllCasesAndCombosForOutput() loadName = "Dead" x = SapModel.Results.Setup.SetCaseSelectedForOutput(loadName) z = SapModel.Results.JointDisplAbs('~64', 1) print(z)

    ETABS (22) API Section Cut Forces

    Ah, helps if I could read. Definitely seems like a bug/feature missing from the ETABs API. Please reach out to them and let them know, this will be helpful for the section cutter tool I hope to be working on in the future.

    ETABS (22) API Section Cut Forces

    I just checked in ETABs, and I do not see a results.setup.sectioncutselectedforoutput in the api documentation. Title of the post makes me think of ETABs, but then you mention SAP200. Also in ETABs, I do not see an option to turn off results for any section cut, seems like you would always want...

    ETABs API- Sapmodel

    Is "myETABSObject" created? Have you tried this from the sample code provided with ETABS 22 documention? Visual Basic for Applications (VBA) via Excel 'create an instance of the ETABS object from the latest installed ETABS Set myETABSObject =...

    Read multiple points on a line element

    My bad, i thought that this was (3) individual line (frame) segments already broken up. It would be helpful to see the applied loading to the element and see what you are trying to retrieve. Can you post some more info? It looks like in your output, there is an applied load at 3.33 ft in...

    Read multiple points on a line element

    Did you see this post? https://www.eng-tips.com/threads/etabs-api-steel-beam-design-shear-reactions.477440/ You can access results for your beam with the code in the post. You can access along stations as well if you like. With this info you could recreate your applied forces. You could also...

    Interactive Data Base Tables in ETABS

    @ElyasCivil What version of ETABs are you running? I tried on v22..0.0 and was able to reproduce the error. Image of the functional load case. Before: After: Error: I would submit a ticket on this to CSI.

    Interactive Data Base Tables in ETABS

    Can you post some screen shots so we can help a bit more? What database table are you editing? How are you editing it? Version of ETABs??

    SEISMIC USER DEFINED LOAD

    Did you manually apply that load to the joint under seismic Y? The double arrow head in your image means that is a twisting moment (Mz), not a vertical load.

    "do you want to reiterate analysis and design" Option not available on ETABS 22

    Interesting, button is gone for me as well. Wonder what happened? S&T

    ETABS API Pier and Spandrel Forces ETABSv1.dll ETABS 21 & 22

    That function returns all of the spandrel forces in the whole project, you would have to do some post processing to edit down the spandrel data to a per level/per spandrel result. It is helpful to think of "ref" as what is returned from the function, anything with the "ref" keyword is output...

    ETABS API add new mass source

    Not many of the API functions have examples written with python as one of the examples, but it's generally not too hard to piece together what to throw in there given the VBA/C# example code. There is some boiler plate python code at the beginning of the API documentation now as well. S&T

    ETABS API add new mass source

    Have you tried through database table methods? Generally, if you can access a table through the GUI, you should be able to programmatically access it through database table methods. My github has a few examples of interacting with database tables...

    ETABS VBA Code

    Hi Raj, I have not coded in VBA before, but the code in C Sharp needs to look a bit different than what you have shown. int NumberItems = 0; int[] ObjectType = null; string[] ObjectName = null; _SapModel.SelectObj.GetSelected(ref NumberItems, ref ObjectType, ref ObjectName); S&T

    ETABS VBA Code

    Rajavardhan, I would think a combination of getting selected objects, filtering out frames and areas and then testing for material property types would do the trick. S&T

    Why moment frames is not seeing any lateral load?

    It is likely that your deck is not very stiff, therefore in your semi rigid diaphragm model, your model is probably very closely mimicking a "flexible diaphragm" where load is distributed based on tributary area. With a rigid diaphragm, your loads are distributed based on the stiffness of the...

    ETABS User Wind Loads on Semi-Rigid Diaphragms

    To be a contrarian, I have not had any trouble with applying user defined loads to semi-rigid diaphragms. Hopefully CSI expanded a bit more than the quote that you posted. If you have your semi rigid diaphragm modelled with enough sub-divisions, I feel like this is a non-issue. I typically...

    ETABS User Wind Loads on Semi-Rigid Diaphragms

    If you put in a single point load, yeah you will get some odd diaphragm results. If you make a rigid diaphragm, you get no results in your diaphragm. If you have wind tunnel loading, you can make your input in ETABs as detailed as you would like. If you want down and dirty, apply the load to...
