某单层球面网壳结构稳定分析

Stability Analysis on the Single-layer Spherical Latticed Shell Structure

以实际工程某单层球面网壳为分析对象,用3D3S软件分析了结构的稳定性能,研究中考虑了几何非线性、材料非线性、荷载的作用方式对单层球面网壳稳定性的影响。计算工程设计方案达到了极限承载力安全储备的要求。

With the single-layer spherical latticed shell structure of a project as an example and with the help of 3D3S soft ware, the paper analyzes the stability of the structure and studies the effects of geometric nonlinearity, material nonlinearity and load on the stability of the latticed shell structure. And the computed designing plan may meet the requirements of the safe storage of ultimate loading ca pacity.
