摘要
将先张法预应力混凝土空心板看作为偏压构件,考虑预应力的轴向力引起的附加弯矩,采用微积分,推导了预应力混凝土空心板反拱度的精确计算理论公式。通过实例计算,将计算结果与一般计算方法的结果进行对比分析。
The pretensioned prestressed concrete voided slab as compression member with eccentricity is considered,The additional bending moment caused by axial pre-stresses is taken into account,and it deduces a theoretical formula to calculate the inverted camber of pretensioned prestressed concrete voided slab in calculus.Through a calculation example,it analyses the calculation results in the article in contrast with the results in general methods of calculation.
