Finite element beam analysis of tapered thin-walled box beams
Abstract This paper presents a one-dimensional finite element analysis of tapered thin-walled box beams under out-of-plane loads and twisting moments by developing new -continuous tapered higher-order beam elements. While higher-order sectional deformations such as distortion were considered earlier, there was no theoretical or finite element analysis on the tapering effect of variable cross-sectioned box beams. Case studies considering tapered box beams with various height-to-width ratios and a system of joint structure with a tapered box beam show that the results by the developed method are comparable with the shell finite element results unlike the stepped Timoshenko beam element results.
Highlights Tapered box beams under out-of-plane loads and twisting moments are analyzed. One-dimensional tapered higher-order finite beam elements are newly developed. The tapering effect is considered with sectional warping and distortion reflected. Beams with various height-to-width ratios and a problem having a joint were tested.
