Starting from virtual work principle, with the combination of fem, the author led into elastic stiffness practical formulation of bi - direction cellular slab. after comparing the bi - direction elastic stiffness formulation with the approximately stiffness formulation, the author drew such a conclusion that if the hole - rib is comparatively big, the elastic stiffness of bi - direction cellular slab calculated by approximately formulation would be comparatively small, and therefore the elastic stiffness could calculated by the formulation illustrated in this paper
本文從虛功原理出發,結合有限元方法,給出了雙向空腹板的彈性剛度實用計算公式,並與近似剛度公式進行對比分析,並得出結論:在雙向空腹板孔間肋較大情況下,利用近似公式計算雙向空腹板的彈性剛度偏小,可按本文提出的彈性剛度公式進行計算。
