内衬波纹钢的钢筋混凝土壳体计算方法

Research on the Calculation Method of Reinforced Concrete Shell with Ripple Steel Plate Lining

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载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。

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.
