End Moments for Joist Girder Moment Frames

We are designing a large warehouse type building with joist girder moment frames in both directions (however no columns are acting biaxially in frames). 

This is a large footprint building and thus lots of frames. 

We need to extract end moments (dead, live, snow, and controlling wind) for the virtual joist girders to put in our drawings. 

What are my options to do this? I really don't want to use a graphical method. I would prefer to have a report that I can export and then manipulate to identify where we can group virtual joist girders with similar end moments. 

Member forces report gives me all the forces along the length of the beam. If there was a way i could limit this to i and j ends?

Member force envelope only gives me the envelope obviously, so I can't get moments for each individual load case.

Thanks! 

  • Hello Ethan,

    I think the best way to extract the end moments is to use beam end forces option available under report setup.

    You can also use load cases of your choice under loading tab and generate the report. Refer help file to know more option related to this.

    You can then export it in Ms word file and from there you can copy the data to excel and work further.

  • For RAM Structural System, the Data Extractor feature in RAM Manager (Post-Processing - Extract Data) can extract the end forces to Excel similar to what Abhisek describes for STAAD. 

    To use this feature, make sure the box marked in the image below is checked before analyzing the load cases in RAM Frame.

    The data checked in the image below represent the member end forces/moments. 



  • wow - this is really exciting. i'm still exploring, but noticing that the member forces table still gives me forces at all nodes along the member. is there a way to report only end forces? or is this just something i'd have to do in excel?

    also can you explain the difference between V_maj1 and V_maj2?

  • If there are internal nodes along the beam, for example those generated from a meshed diaphragm or two-way deck or intersecting vertical brace, then those nodes will be included in the table. I do not see a way to generate the report with only the end forces, unfortunately.

    V = shear, maj = major axis, 1 = end 1 of beam segment, 2 = end 2 of beam segment
