simple beam with torsion

Hello,

In modelling a simple beam.

What's' the support condition when modelling a simple beam with torsion?

Hi @saclovitzky . Not sure of what you meant ,but if it is a simple beam on a 3d model , then you have to block the moment/rotation in the bar axial direction at least on one of the bar end nodes.

@Rafacascudo ,pls. see attached file. Can you update the support.And also, in running the design, does it recognize(included) the torsional mo9ment in the reinforcement design?

thanks for the help.

As I said in my 1st post , it needs at least a Rx restraint on one of the supports or structure will be considered unstable by RSA.

For the RC design , I cannot help you as I don´t use the RC design module as RSA does not have the brazilian codes implemented.

But most probably , torsion is taken in account.
