摘要：基于平截面假定和混凝土应力与应变关系，根据平衡条件推导出了混合配筋预应力环形截面构件正截面受弯承载力理论计算方法，结合混合配筋预应力混凝土管桩（PRC桩）算例，将理论计算方法与GB 50010—2010《混凝土结构设计规范（2015年版）》中的计算方法进行了比较，两者吻合程度较好，表明将GB 50010—2010中分列的两个公式叠加后得到的配筋公式适用于PRC桩的受弯承载力计算。 Abstract: Based on the plane section assumption and the relationship between concrete stress and strain, the theoretical formula method of flexural capacity of normal section of prestressed and reinforced circular section component is deduced according to the equilibrium conditions. Combined with the calculation example of prestressed and reinforced concrete piles(PRC pile) and prestressed high-stressed concrete pile(PHC pile), the calculation results of the theoretical formula meothod are compared with the GB 50010—2010 Code for Design of Concrete Structure, the coincidence degree of the two is good, which shows that the formula obtained by superposition of the two formulas listed in GB 50010—2010 is suitable for the calculation of flexural capacity of PRC piles.

Abstract: Based on the plane section assumption and the relationship between concrete stress and strain, the theoretical formula method of flexural capacity of normal section of prestressed and reinforced circular section component is deduced according to the equilibrium conditions. Combined with the calculation example of prestressed and reinforced concrete piles(PRC pile) and prestressed high-stressed concrete pile(PHC pile), the calculation results of the theoretical formula meothod are compared with the GB 50010—2010 Code for Design of Concrete Structure, the coincidence degree of the two is good, which shows that the formula obtained by superposition of the two formulas listed in GB 50010—2010 is suitable for the calculation of flexural capacity of PRC piles.
