摘要
本文基于能量法推导出了船舶板架结构在两侧边受到弹性转动约束时,计算临界压缩强度的分离梁解和正交异性板解。通过计算比较可知,推导出的解能够简单、可靠且灵活地计算船舶板架的稳定性问题。
This paper derives both the discrete beam solution and the orthotropic plate solution for calculating the critical compressing strength when the ship grillage structure is constrained by elastic rotation at the two sides. The solutions derived can be used to calculate the stability of the grillage easily, reliably and flexibly.
