板锥网壳结构的连续化分析

A Continuum Analogy Method For Plate-Cone Reticulated Shell

板锥网壳结构是一种受力性能合理 ,技术经济效益良好的新型空间结构形式。本文将板锥网壳结构连续化为能共同作用的特殊形式的三层薄壳 ,按薄壳理论建立其位移法和混合法的基本微分方程。通过对微分方程的求解 ,计算其整体位移及结构内力。该法具有一定的精度 ,可宏观地了解结构的力学性能 ,并可用于板锥网壳结构的初步设计。

Plate cone reticulated shell is a new type of space structures with good mechanical behavior and technical economy. In this dissertation, plate cone reticulated shell is equated to three layer interactive thin shell. Derived on the basis of the theory of thin shells, the governing differential equations are established from the displacement method and the mixed method of derivation. The solution of this system of differential equations gives the displacements and internal forces.
