Influence of Span-depth Ratio to the Ductile Property in Prestressed Concrete Hollow Slab

摘要

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, strength of concrete, strength of steel bar, reinforcement ratio, span-depth ratio and stretching control stress are analyzed and compared. The influence of span-depth ratio to the ductile property in prestressed concrete hollow slab is discussed by numerical simulation.
