Basics of Dynamic Analysis in RISA-3D

Modeling and analyzing structures for dynamic conditions is essential to understanding how a structure will react to loading such as wind and seismic. These analysis types can include simple free vibration analysis as well as more advanced response spectra and time history analysis. RISA-3D is adept at handling a variety of dynamic analysis situations while ensuring that the required code parameters are followed.

Is there a way we can get a copy of this model you are using?

[@hazimalwaali9507]

For many reasons and for Risa 3D limitation I prefer Staad Pro and RAM products ( Bentley).

You are not telling the truth about our market. People in our part of the world use the software you mentioned and others because they get cracked versions free, whereas RISA has not been cracked. 99% of people in our part of the world are like that!

@@mohammedalshankyty3241 No Mohammed I live ib the USA and I have full version of SaadPro and all RAM product with paid subscription, thank you.

@@hazimalwaali9507 As an Arabic language speaker, one important advantage the programs you mentioned have for you is that there are plenty of TH-cam videos in the Arabic language for the programs you mentioned. Again, this is the result of the widespread illegal software use in our part of the world which opened a window of opportunity for providing tutorials in Arabic. The availability of crack for the mentioned software made them very widespread. RISA is difficult to crack. I remember that one Syrian guy managed to crack RISA 3D version 4 a long time ago and non since then.
Of course, being in the USA, you would have licenses where punishment for illegal software is very tough. I doubt that you would if you were living in your original homeland.
Having said that, I must point out that the reason which made me reply to you is that I found it very rude of you to come to a RISA website and submit the comment you made.
