This project will optimize the strength, stiffness, vibration characteristics, acoustic qualities and fire resistance of cross-laminated floor systems utilizing a composite concrete and cross-laminated timber product. This project includes development, testing and optimization of an economical shear connector (to connect the CLT panel to the concrete slab) that will be compared with existing screw and steel plate solutions. The resulting prototype floor system will be tested at full scale.
Three timber-concrete composite floor assemblies were evaluated for fire performance to understand how shear connectors might impact heat transfer into the assemblies. The floor assemblies tested included a CLTconcrete floor with self-tapping screws, a screw-laminated 2x8-concrete using truss plates, and a LVL-concrete using...
