• EXPERIMENTAL STUDY ON FLEXURAL BEHAVIOR AND STRENGTH UNDER SAGGING AND HOGGING BENDING NOMENT OF A COMPOSITE GIRDER WITH HYBRID SLAB

抄録

 This paper describes experimental results on cracking behavior under hogging bending moment and flexure strength under sagging bending moment of a composite girder with the newly developed hybrid slab. The slab has a bottom plate, longitudinal ribs welded to the bottom plate, laying bar studs inserted into the ribs and reinforcing bars longitudinally and transversely installed on the top of the ribs. Under hogging bending moment, it was shown that produced crack width was considerable small compared to that reported in other type of hybrid slabs. Under sagging bending moment, the obtained ultimate flexure strength was a little bit smaller than plastic moment. However, taking into account of ductility condition (concrete crushing before reaching plastic moment), the obtained strength can be predicted with good accuracy.
