Discussion on the Influencing Factors of Deflection-Span Ratio at Failure in Prestressed Concrete Hollow Slab

Abstract:

The numerical analysis method is applied to simulate the whole process of bending. Keeping the section dimensions and the types of loads constant in prestressed concrete hollow slab with mid-strength spiral-rib steel wire, span-depth ratio, reinforcement ratio, strength of concrete, strength of steel bar and stretching control stress are analyzed and compared. The influence of span-depth ratio, reinforcement ratio, strength of concrete, strength of steel bar, and stretching control stress on deflection-span ratio at failure of prestressed concrete hollow slab is discussed by numerical simulation.
