I checked the forum and the manuals but there was no solution that actually worked to my specific problem. I changed maximum number of iterations in the "global iterative strategy" and "element iterative strategy", increased the number of steps of the loading phase, but still there's a big ...

Good morning,

I modelled a 4 floor 3D steel braced frame using infrmFB element to characterise the diagonals and elfrm elements for the horizontal and vertical elements. The beam-column joint are considered pinned and are realised with M2 releases. The diagonal-column joint is modelled with a ...

Dear Zoi Gronti,

sure, I will send you everything.

Thank you

Hello,

i was trying to reproduce by hand the calculation of the ultimate chord-rotation capacity of RC elements (beams and columns) by NTC2018, that is equation 8.7.2.1.

Following costant and timestep properties in the Detailed Calculations(Annex) tab of the Print‐out Options module of ...

Dear support Team,
Thank you for your answer.

What does cause these fictitiuos axial forces?

Thank you
Giovanni

Dear Support Team,
Thank you for the answers

I have two more questions:

1) Why is there a very high axial force on the horizontal elements modelled with InfrmFP and rigid diaphgram? For example, in my very simple frame (two RC frames, two storeys), at the peak of shear of the pushover analysis ...

Dear Support Team,

I'm trying to check the chord rotation capacity by Italian NTC2018 Code for a very simple 3D RC frame (two frames, two storeys) by using a Pushover analysis and checking the output values when the first chord rotation performace criteria is reached.

I've been having issues in ...
