Numerical Analysis on the Bending Performance of Prestressed Superposing-Poured Composite Beams

Table 1

Description of the superposing-poured beam model.

Model no.	Prestressing schemes	Casting interval time
B1-1	Superposing-poured beams no prestress	45 minutes
B1-2		14 days
B2-1	Superposing-poured beams with straight linear prestressed bars	45 minutes
B2-2		14 days
B3-1	Superposing-poured beams with curved prestressed bars not across the casting interface	45 minutes
B3-2		14 days
B4-1	Superposing-poured beams with curved prestressed bars across the casting interface	45 minutes
B4-2		14 days
