A 24-dofisoparametric finite element has been presented for the analysis of generally laminated curved beams. The effects of shear deformation and rotary inertia have been accounted for using the shear deformation theory which employs nonlinear shear strain variation across the section. Thus it is not necessary to specify the shear correction factors in the present element. The torsional response has been incorporated according to the elementary theory of torsion. It is shown that for certain unsymmetrically laminated curved beams the in-plane and out-of-plane motions are coupled. The numerical results presented illustrate the performance of the element and the effect of coupling.
