摘要：
Structures adopting laminated glass (LG) as load carrying members are increasingly used in aesthetic demanding buildings nowadays. LG columns are vulnerable to out-of-plane flexural buckling under axial compression. However, a complete design method applicable to the flexural buckling behavior of LG columns composed of three or more glass panes is still unavailable. Based on the model of composite beams that takes into account the sliding effect between glass panes, a calculation method that gives the critical buckling load and the strength check criteria for the multi-layer LG columns under axial load were deduced in this paper, and the simplified formulae and the stability factor-slenderness ratio (φ-λ) buckling curve suitable for engineering design practice were proposed. The proposed formulae and the φ-λ buckling curve were verified by correlated data collected from published literatures. The results of verification show that the proposed analytical formulae for the critical buckling load and the ultimate strength of multi-layer LG columns are of high accuracy, and the proposed design φ-λ curve can ensure the safety of the components. © 2021, Editorial Office of Journal of Building Structures.
