| Abstract: | This article considers the pretensioned prestressed concrete voided slab as compression member with eccentricity,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. |

| Keywords: | pre-tensioning technique prestressed concrete compression member with eccentricity inverted camber |
