curved beams 2

[Ahmadshag]

Hello gentlemen
i have a question
i have faced a problem with this curved beam in my graduation project
the shear+torsion forces exceed limits" that's what etabs keep saying
any one have an idea to solve this problem ?

Check by hand. Probably the shear and torsion do exceed limits.

i did check by hand and it's exceeding limits
but i don't what to do ! should i change the section from concrete to composed or is there any other solution ?

You need to provide more information about the structure, the spans and loads.

maybe you can assign a 0.001 torsional modifier to the frame element.
