Development of a New Composite Connector for Timber–Concrete Composite Connections.

This study presents a new design of a wood–concrete connector that meets ductility and stiffness requirements in accordance with Eurocode 4. An analytical approach and a numerical model developed on Abaqus are proposed. The study is completed by experimental push-out tests and a specially made composite beam. Two types of timber concrete composite (TCC) are considered in this study. The first connector (stud connector), was applied in construction and its performance compared to that of a recently developed connector. The analytical calculation of stiffness was performed using the relevant standard. In addition, different connector configurations and spacing were tested in push-out and beam tests. The results showed that this new connector has interesting characteristics such as stiffness (4,068.12 kNm2) and maximum strength (24,70 kN) compared to existing connectors. [ABSTRACT FROM AUTHOR]
