Abstract
A connector for connecting a wood substrate to a concrete layer. The connector comprising a shank adapted to engagement with a bore in the wood substrate with a length of the shank aligned with a central axis of the bore, the shank having at least an external portion made of a cement-based composition. In the built-up system, the connectors can have transversal ductile collapse characteristics providing a structural ductility of at least 50% to the built-up system with the wood substrate and concrete layer maintaining an elastic behavior upon the transversal ductile collapse of the plurality of connectors.
Claims24
A connector for connecting a concrete layer to a wood substrate;
- the connector comprising an elongated shank adapted atoll for engagement with a bore in the wood substrate with a length of the shank aligned with a central axis of the bore, the shank having an external portion made of a fiber-reinforced cement-based composition, and a core surrounded by the external portion and forming an internal portion relative to the external portion, the core being made of a material having at least 100% more ductility than a ductility of the cement-based composition forming the external portion.
A built-up system comprising:
- a wood substrate;
- a concrete layer juxtaposed with the wood substrate;
- and
- a plurality of connectors interspaced from one another and each being made integral to the concrete layer, protruding out from the concrete layer into the wood substrate, and having an outer layer of concrete composition;
- the connectors having transversal ductile collapse characteristics providing a structural ductility of at least 50% to an overlay system;
- wherein the wood substrate and concrete layer maintain an elastic behaviour upon the transversal ductile collapse of the plurality of connectors.
