We present an asymptotic analysis of the three-dimensional problem for a thinwalled beam with rectangular cross section of side $\varepsilon$ and $\varepsilon^2$ for an anisotropic, inhomogeneous along the longitudinal axis, material with residual stress. We show that in the limit model bending, twisting and extensional problems are coupled. We also obtain the equations of equilibrium under the least symmetry group which uncouple them.
Keywords: $\Gamma$-convergence, dimension reduction, thin walled beams, residual stress
