摘要
本文以新建武汉站幕墙方案设计为例,针对自平衡支撑体系在玻璃幕墙中的应用,对其整体进行了系统的分析。根据静力计算的结果确定杆件断面,运用有限元分析软件Midas,对结构整体进行了特征值屈曲分析,在考虑了初始缺陷和几何非线性的情况下,进行非线性稳定性分析。通过上述分析,对幕墙结构方案的最终确定提供了有效的方法,给完成一项较大的幕墙工程提供了一个可以借鉴的方法。
In this article,we take the project of the glass curtain wall for New Wuhan Railway Station as an example to present the overall analysis on self-balance supported system in the application of glass curtain walls. The member section is selected by the static calculation results of the structure. The upper limit of buckling load is estimated after eigenvalue buckling analysis by applying Finite-Element Analysis Program-Midas. In consideration of the effects of the initial defect and geometry nonlinearities,we analyze the stability of the structure. The work can be provided for reference in determining the plan of the curtain wall structure and accomplishing a large scale project.
