本文在F.K.孔研究的基础上,考虑预应力混凝土海上采油平台罐体结构特点,推导了计算罐体最小截面厚度的方法及计算截面内、外缘预应力钢筋面积的简明公式,建立这些公式的主导思想是合理的预应力设计。文中给出实用计算步骤并附有计算实例,按本文方法计算可以避免多次修改截面厚度和调整内、外缘预应力钢筋面积,从而为选择最佳设计方案提供了捷径。
Based on the research of FK hole, considering the structural characteristics of tank of prestressed concrete offshore oil platform, the method of calculating the minimum cross-section thickness of tank and the concise formula of calculating the prestressed rebar area inside and outside the cross-section are derived. Based on these formulas The dominant idea is reasonable prestress design. In this paper, practical calculation steps are given and examples are given. Calculations based on this method can avoid changing the thickness of the section several times and adjusting the area of the prestressed steel bars on the inner and outer edges, thus providing a shortcut for choosing the best design scheme.
