can I create a composite beam with user defined material properties in robot structural analysis 2025?
Solved! Go to Solution.
yes . Just choose the base material(steel or concrete) and the section properties will be calculated based on this choice.
Just be aware that ,for composite sections , IX will be not calculated by RSA . You will have to insert it manually on "Ruser" section database.

Thank You rafacascudo! Do I have the option of changing the base material?
You can choose any material as base material of any available database in RSA ,including custom materials created by you.
Also , check this thread to related problems about composite sections which I do not know if they have been corrected

Thank you Rafacascudo the reason why Ix is not calculated is probably because it is defined as the axis into the paper/screen. Perhaps the solution would be in changing the section axes to x and y in the section definition instead of the y and z which are automatically prescribed by the system in Robot 2025 (as shown in the screen shot below).
Not possible. Bending inertia axes will always be Y and Z in RSA .
