After reading your post yesterday firstly I opened Concept and looked in the slab properties how I can release the torsion ,couldn't find It the first time then after posting u back I found it,anyway,a curved beam is a beam that has torsion applied on it from the eccentricity Of the applied load on it to the shear center of the beam,in symmetric shapes the shear center is in the middle of the section(the Center) as load at any point is eccentric from the center in any point besides the point the load affects it plus every perimeter beam Bears torsion because the weight of the slab is just from one side and have no load from the other side to neutralize it and not Released at it's ends so it won't resist torsional moments.
