Abstract

The provisions in the ACI Code for shear i.s prestressed concrete were developed from tests on prestressed girder sections. Their applicability to prestressed hollow-core slabs has been inferred. This  paper reports the observations from a study of shear in dry cast, extruded hollow-core slabs. The basic conclusion was that these slabs do indeed  meet the criteria of the ACI Code.Additionally, in the study of  web shear, the bond length of prestressing strands was severely tested with the conclusion that the present ACI Code (318-83) development length provisions are conservative.
