Deconstructable connector for TCC floors using self-tapping screws

Timber-concrete composite (TCC) systems are effective solutions for the construction of new structural floors and rehabilitation existing ones. Nevertheless, subject design disassembly TCC is still an area that requires further research development. In this paper, concept a deconstructable connector using self-tapping screws presented aimed to be used both prefabrication cast-in-situ floors. On total 61 T-section glulam-concrete specimens, shear properties were evaluated compared equivalent permanent connectors. The experimental investigation was performed single cross-paired screw arrangements with various insertion angles two different types screws. A comprehensive failure analysis differences between developed ones described. Overall, demonstrated similar behavior connectors only marginally smaller strength stiffness could therefore as environmentally friendly solution connections.
