Both the exact d osed —form solution and a numerical solution by the differential quadrature method (D. Q. M.) are obtained to predict the ou t-of-p lan e behavior of a curved beam subjected to torque, based on the curved-beam version of the shear deformable (Bresse-Tim oshenko) beam theory. Deflections, twist angles, angles of rotation, bending moments and twisting moments are calculated for the case of a circular arc of circular cross section with clamped and simply supported boundary conditions, and results obtained by both methods are compared. The D. Q. M. gives good accuracy for only a limited number of grid points.
