Bending properties of deconstructable cross-laminated timber-concrete composite floor elements

Design for disassembly using deconstructable connections facilitates recycling and reusing of building materials and, therefore, reduces waste management problems at the end service life. In this regard, a timber-concrete composite connector self-tapping screws has been developed Aalto University. presented research, an experimental investigation was performed to further evaluate effectiveness in fabricating cross-laminated timber (CLT)-concrete floors. For purpose, several CLT-concrete beams were fabricated 5-layer CLT low-shrinkage concrete. Each beam contained one row connectors represent strip full-scale floor. The vibration performance, bending properties, interface slip, failure modes, ease investigated. results compared with ones from reference group regular screws. Overall, exceptionally well by attaining 98.5% average stiffness beams. load-carrying capacity also similar but governed plate. characteristics comparable both groups. After test, disassembled. Although had exposed unproportionally large deformations under load, process successfully.
