A hybrid stress finite element for linear static analysis of thin-walled beams is presented. The element is based on Vlasov theory. The hybrid stress formulation is particularly suitable in this case where displacement assumption is not necessary and a simple polynomial assumption for independent stress resultants is sufficient to form the element stiffness matrix. The result is a simple and elegant element, which is accurate and cost effective. The formulation is assessed by analyzing a structure having open and closed sections. The results are in perfect agreement with previous solutions.
