DEVELOPMENT OF STEEL-PLATE BEARING FOR THE ERECTION OF PRECAST PC SLABS

Abstract

An experimental study for the development of steel-plate bearing applied to the erection of precast PC slabs has been made. A total of 6 PC beam specimens having different embedding length of anchor bolts and the spacing between stirrups have been used, and a simple-beam type loading test was carried out. It was found that the strength and deformation properties of the bearing increases as either the embedding length increases or the spacing between stirrups decreases. A mixing of failure modes was also observed ; the bond splitting failure of anchor bolts (the major failure mode for all specimens) was accompanied by the bending failure at a beam section.
