Dlubal PLATE‑BUCKLING 8.29.01

Dlubal PLATE-BUCKLING 8 for Windows，它可以作为 RFEM/RSTAB 的附加模块使用，也可以作为单独的独立程序使用。它根据以下标准对矩形板进行板屈曲分析： EN 1993-1-5：2006 DIN 18800-3：1990-11。

Overview of Dlubal PLATE-BUCKLING 8 Benefits
Dlubal PLATE-BUCKLING 8 优点概述

Designs are performed in iterative steps by eigenvalue calculation of the ideal buckling values for the individual stress conditions as well as of the buckling value for the simultaneous effects of all stress components.
通过计算各个应力条件下的理想屈曲值以及所有应力分量同时作用的屈曲值的特征值，以迭代步骤进行设计。

The Dlubal PLATE-BUCKLING analysis is based on the method of reduced stresses, comparing the acting stresses with a limit stress condition reduced from the yield condition of von Mises for each buckling panel. The design is based on a single global slenderness ratio determined by the entire stress field. Therefore, the analysis of single loading and subsequent merging using interaction criterion is omitted.
Dlubal PLATE-BUCKLING 分析基于折减应力方法，将每个屈曲板的作用应力与从 von Mises 屈服条件折减的极限应力条件进行比较。该设计基于由整个应力场确定的单个全局长细比。因此，省略了使用交互准则对单个载荷和后续合并的分析。
