This paper presents a numerical solution to the differential equations resulting from Vlasov Theory of nonsymmetric curved beams with thin walled open cross section. A linear elastic structural behavior is admitted and the static analysis is performed by using the Method of Central Finite Difference to solve the referred differential equations. Due to the beam curvature, the analysis envolves the coupling between bending and torsion, and both Saint-Venant and warping torsions are taken into account. Beams with any combination of the boundary conditions and intermediary supports are considered, including pinned or fixed ends in torsion and bending. Numerical results obtained through a computer program implemented in a PC - compatible microcomputer system are compared to other technical references, presenting Showed a good correlation.
