Abstract
Experimental and analykal studies of composite wood-concrete floorldeck systems
have been ongoing at Colorado State University. A novel shear keylanchor detail of
overlaying solid wood floors in office buildings with a concrete layer, thus creating
a composite floor, was adapted for this study. The detail utilizes a notch to transfer
bearing stress and shear stress in the joined materials for interlayer force transfer,
rather than connector shear. Compared to ordinary mechanical connectors, the
connection detail develops a substantially higher degree of composite action.
Systems are being studied for residences, offices etc. and short span bridges.
Laboratory testing included pull-out tests on th
