Finite element analysis on mechanical properties of new section of aluminium alloy members under bending moment

摘要

Aluminium alloy structures are widely used in civil engineering. In this paper, nonlinear analyses were carried out on the aluminium alloy members under bending moments by finite element analysis. The parametric study shows that the ductility of the new section is better than that of the I-section. The stable performances of the aluminium alloy members of the new section are better than that of the I-section. The failure modes of the aluminium alloy members under bending moment are strength failure. With the type of the new section taken in this paper, the inelastic amplification factor of the members of 6061-T6 is 1.6 and that of 6061-T4 is 2.0.
