摘要：
Chinese 701 aluminum alloy is a new type of building material with excellent performance. Compared with the traditional 6061-T6 aluminum alloy, 701 aluminum alloy has higher strength, better ductility and has a broad application prospect in towers. Firstly, the test of 24 Chinese 701 aluminum alloy L-section axial compression members was finished, and the ultimate bearing capacity and failure mode of the component were obtained; then a numerical analysis model was established and verified by the experimental results. Then, a large number of numerical analyses have been completed considering the influence factors such as slenderness ratio, section size, and initial bending. Finally, the experimentally measured stability coefficients were compared with the stability coefficients calculated by the Chinese code. The comparison results show that the overall stability bearing capacity of the 701 aluminum alloy L-shaped axial compression member can be calculated using the formula in Chinese "Aluminum Structure Design Code".
