根据经典壳体理论的柱壳微分平衡方程组,假设肋条、钢筋、波纹钢板的抗拉、抗弯作用均匀分布在肋条支持的范围内,忽略它们的抗扭作用,推导出了内衬三维波纹钢板的钢筋混凝土壳体的基本微分平衡方程组。采用三角级数法求解了均布荷栽作用下的壳体的中面位移,并与未衬三维波纹钢板的壳体进行了比较。通过比较可以看出,三维波纹钢板对于限制结构的变形有着十分明显的效果。
根據經典殼體理論的柱殼微分平衡方程組,假設肋條、鋼觔、波紋鋼闆的抗拉、抗彎作用均勻分佈在肋條支持的範圍內,忽略它們的抗扭作用,推導齣瞭內襯三維波紋鋼闆的鋼觔混凝土殼體的基本微分平衡方程組。採用三角級數法求解瞭均佈荷栽作用下的殼體的中麵位移,併與未襯三維波紋鋼闆的殼體進行瞭比較。通過比較可以看齣,三維波紋鋼闆對于限製結構的變形有著十分明顯的效果。

Based on the classical differential equilibrium equation of shell, assuming that the abilities resisting tension and bending of the reinforcement bars, the three-dimension ripple steel plates and the ribs are equably distributed in the range that the ribs act on and ignoring their contributions to torsion, the basic differential equilibrium equations of it is derived in the 1st part of this paper. The displacement of the structure under the case of distributed loads can be solved by the trigonometric series method. Comparing the results with those of the ordinary shell, it can be concluded that the contributions of the three-dimension ripple steel plate arenotable.
