Vibration Analysis of Closed Thin-Walled Box Beams Using High-Order Beam Elements
초록
This paper proposes a new 'finite element for the vibration analysis of thin-walled beams of rectangular closed sections. To predict the dynamic behavior of the thin-walled beam accurately, warping and distortion deformations should be considered for the analysis. The motivation of the present development is that conventional beam elements cannot describe correctly deformations such as warping and lozenging which are not negligible in some situations. Several numerical examples are studied to confirm the validity of the present element.
