Complex Parial Box Girder
Overview
⦁ The complex partial box girder (CPB) method is a composite
girder method in which I-type girder with excellent bending
rigidity is applied to the center and concrete is placed on the
top of the lower flange of the BOX-type girder with excellent
twisting rigidity at the pier point to increase structural
rigidity and reduce the amount of steel.
Characteristics of Complex Partial Box
Girder
⦁ The complex partial box girder (CPB) method compensates for the
shortcomings of steel that is vulnerable to compression by
forming a plate girder-shaped cross-section in the center of the
span and applying a double composite cross-section with concrete,
a material that is highly resistant to compression.
⦁ In the center of the span, an I-shaped cross-section with
excellent resistance to bending was added to the cross-section to
compensate for the shortcomings of the tendency to be
over-designed when designing with a steel box girder to enable
efficient design. Accordingly, it is a new type of method that
can reduce the weight by reducing the amount of steel in the
center of the span when applying the curved bridge..
