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

Abstract:

Article Preview

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.
