Experimental characterisation of the moment-rotation behaviour of beam-beam connections using compressed wood connectors

Proposing New Adhesive-Free Timber Edge Connections for Cross-Laminated Timber Panels: A Step Toward Sustainable Construction

“…The first and second verification models were simulated based on a four-point bending experimental study of GLT beams done by Mehra et al [33]. The employed GLT test involves an adhesive-free timber edge connection, and there is no related test regarding CLT.…”

“…The third verification is related to the CLT lamella without an edge connection. The study from Mehra et al [33] is on the feasibility of using CW connectors in heavy timber connections and compares the performance of this approach with commonly used steel-timber connections. The study used GLT beams, CW plates, and CW dowels to produce all-wood beam-beam connections.…”

“…1 and No. 2), the standard wood was made of Douglas fir, according to Mehra et al [33], and its density was 570 kg/m 3 . The applied CW in this model used Scots pine (Pinus sylvestris) as the original material.…”

“…However, this joint highly relies on the metallic screw for fixing the timber connector, which is an unpreferable factor based on the environmental point of view. On the topic of adhesive-free timber edge connections in timber structures, Mehra et al [23] concluded that compressed wood connectors have the potential to be an alternative to high embodied energy steel connectors and synthetic adhesives in glued-laminated timber (GLT) construction. The study showed the feasibility of replacing steel connections with adhesive-free timber connections through experimental tests.…”

“…Furthermore, such an approach poses the potential to enhance material performance and contribute positively to its end of life [1]. Nevertheless, existing research identifies a critical gap within the wood-to-wood timber connections to tackle better design, manufacture, assembly, and deconstruction (DfMA + D) [20]. Consequently, this study endeavours to explore the application of Computer Numerical Control (CNC) technologies in conjunction with the material's response to changes in relative humidity.…”
