Okay, thank you very much. I will look at all of these things. Sometimes I feel like the Abaqus user guide could be better at explaining such things, especially for someone doing explicit dynamic analysis for the first time. Can I ask you how you would go about modelling the dynamics of...

Just in case it is helpful here are some numbers: Calculated moment capacity: 373 kNm Moment at middle(L/2) from dead load: 59,4 kNm Moment from full load over 10 sec: 140kN -->(PL/4) 350 kNm Total = 409,4 at 10 sec

Hi FEA Way I didn't know contact could have a big impact, I removed it entirely in my static model and just used displacement BC since I couldn't get contact to work like in my dynamic analysis. Anyway here is my CAE file. You can probably use a coarser mesh than me, I just hoped my results...

Hi I'm trying to model progressive collapse of a reinforced concrete building and to be sure my materials behave as I expect I have created a simply supported beam where I load it until failure. I hoped that I would see the moment capacity of the beam at least be the same as my analytical...

Hi FEA way Thank you very much for your help. Your solution worked for me. It is a bit unfortunate that I have to make multiple sets since this limits scaling the solution to a large 3D model. It would be too tedious to create all those constraints for a model with many nodes. Maybe I could...

Thank you FEA way I will try to get your suggestion to work.

Hi Mustaine This is just a school problem, so it doesn't exist in real life. I'm trying to model a 2D frame with some live load and perform a frequency analysis to obtain the modes. Problem is that it would be wrong to just increase the density of the beam itself because the center of mass for...

Yes I know how to add mass to the points, sorry I should have been more clear. I want a distributed mass on the beam but with a distance, so essentially I want to know how I can make connectors between every mesh-node on my beam to the nodes on my 'mass beam'. Well unless there is a smarter way...

Hi I'm trying to model some additional mass at some distance from a cantilever beam. But I can't figure out how I would do that so some advice would be very nice. I have tried drawing my problem, please see the attached image. What I've tried: I have tried creating an extra beam with...
