本文首先讨论双向加肋壳, 线性理论应用的可能性。计算结果说明, 当肋比重较大时, 线性理论与实验结果估计可以相当一致。其次, 在线性理论的基础上,讨论了Теребущко所没有讨论过的,矩形格框和薄壁断面肋加强的情形。最后, 实例计算表明矩形格框比方形格框, 对减轻结构重量来说更为有利。 This article first discusses the possibility of applying a two-way ribbed shell to linear theory. The calculation results show that when the rib weight is larger, the linear theory and experimental results can be estimated fairly. Secondly, based on the linear theory, we discuss the cases of rectangular grids and thin-walled section ribs not discussed in Теребущко. Finally, the case calculation shows that the rectangular box is more advantageous than the square box to reduce the weight of the structure.
