| Outline of Final Research Achievements |
For beams with thin-walled wide cross-sections or complex composite cross-sections, deformation of the cross sections deteriorates accuracy of the conventional beam theory. In this study, a mathematical homogenization method is applied to beams to obtain the deformation of the cross section via finite element models with higher accuracy, and a new beam theory that can incorporate this result as a cross-sectional parameter is developed. The developed beam theory realizes accurate analysis of structures which the conventional beam theory has difficulty to treat.
