This paper presents an analysis of curved box beam element considering shear lag and warping torsion effects. In this study, the variation method is used to formulate the stiffness matrix and nodal loading vectors. In the application example, numerical results obtained by this proceeding are correlated with the predictions of finite shell element method, and can provide reference for the design of related engineering structures.
