在单层索网点式玻璃幕墙中,由于柔性索网的影响,玻璃面板的支承点产生不均匀的强迫位移,相应规范的计算理论已不再适宜。通过对单层索网点式玻璃幕墙中玻璃面板的计算方法进行探讨,建立了考虑索网影响的有限元耦合模型。与现行计算理论的比较表明,支承索网对玻璃面板的影响不能忽略。
In the glass curtain wall supported by single-layer cable net, the supporting points of glass panels have unevenly displacement under the influence of the single-layer cable net, and the design method in corresponding codes are no more applicable. In this paper, the FEM coupling model is set up to analyse the glass panels. By comparing the results from coupling model and traditional model, we come to the conclusion that the influence of single-layer cable net on analysis of the glass panels cannot be neglected.
