全玻幕墙中玻璃肋稳定性的理论分析及设计方法研究

在玻璃肋稳定性试验研究的基础上，文章建立了有限元模型，对玻璃肋的稳定承载力进行数值模拟，基于弹性稳定理论，利用能量法对全玻幕墙中通过结构胶和玻璃面板连接的竖向单片玻璃肋稳定承载力进行理论推导，提出对应的屈曲临界荷载计算公式。经验证，计算公式与试验研究、有限元分析结果吻合良好，这将为建立全玻幕墙玻璃肋的设计方法奠定理论基础。

Theoretical analysis and design method for stability of glass ribs in full glass curtain wall

On the basis of the experiment research on stability of glass ribs, the finite element model is established to simulate the stability of glass rib. Based on the elastic stability theory, the stability bearing capacity of single-piece glass ribs connected with glass panels and silicone structural adhesive is studied and a design formula for the buckling critical load is put forward by the energy method. The calculation results by the proposed formula coincides well with the experimental results and the finite element analysis results, which will lay a theoretical foundation for the stability design of glass rib in the full glass curtain wall.
