【Abstract】 in this paper,the possible shear buckling of the web that may appear in the aluminum alloy beam is studied by the finite element method,and the stability of the shear plate of aluminum alloy is analyzed. The finite element model is verified by previous experimental conclusions. The factors affecting the shear buckling of aluminum alloy are analyzed,and the critical buckling strength and post buckling strength of aluminum plate are given. The results show that the results obtained by the formula are more accurate and suitable for the stability design of aluminum alloy beams.更多还原
