Abstract
Multi-cell thin-walled beams showed excellent energy absorption efficiency under various load conditions. However, the theoretical prediction of their bending resistance is quite a challenging task. In this work, the three-point bending collapse of thin-walled rectangular beams with single-, double-, and triple-cell sections is investigated experimentally and numerically. Two finite element schemes: the shell element scheme and the solid element scheme, are employed to simulate the experimental tests, and the features of the two schemes are compared. The influence of friction coefficients on the force response and deformation mode of the beams is analyzed. Finally, a constituent element method is proposed to predict the bending responses of multi-cell beams, and the feasibility of the method is demonstrated.
