摘要

为了分析无预应力索或细长支撑加筋的格构壳体的屈曲行为，有必要考虑支撑的无压缩特性。本文提出了一种考虑支撑无压缩特性的线性屈曲分析方法。此外，为了检验该方法的有效性，将其结果与具有几何非线性和材料非线性的非线性屈曲分析结果进行了比较，以表达支架的无压缩特性。结果表明，该方法能够很好地预测拉筋加筋格构壳体的屈曲行为。

Linear Buckling Analysis Considering No-compression Property of Metal Grid Shells Stiffened by Tension Braces

In order to analyze the buckling behavior of lattice shells stiffened by cables or slender braces without pre-tension, it is necessary to consider the no-compression property of braces. This paper proposes an innovative method of linear buckling analysis that considers the no-compression property of braces. Moreover, in order to examine the proposed method's validity, its results are compared with the results from a nonlinear buckling analysis with geometrical nonlinearity and material nonlinearity to express the no-compression property of braces. The results show that the proposed method can well-predict the buckling behaviors of lattice shells stiffened by tension braces.
