(Departamento de Ingeniería en Maderas de la Universidad del Bio-Bio en Concepción, Chile, 2019)The use of fast-grown timber in the manufacture of engineered wood products is increasing; however, the fast growth rate results in a low-density timber that is susceptible to significant swelling and shrinkage deformations ... -
Experimental characterisation of the moment-rotation behaviour of beam-beam connections using compressed wood fasteners
Mehra, Sameer; O'Ceallaigh, Conan; Sotayo, Adeayo; Guan, Zhongwei; Harte, Annette M. (Elsevier, 2021-09-16)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -

Mehra, Sameer; O'Ceallaigh, Conan; Sotayo, Adeayo; Guan, Zhongwei; Harte, Annette M. (Elsevier, 2022-04-04)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
The influence of age on the timber properties and grading of Scots pine and larch in Ireland
Gil-Moreno, David; Manso, Rubén; O’Ceallaigh, Conan; Harte, Annette M. (Oxford University Press, 2023-06-13)Scots pine (Pinus sylvestris L.) and larch (Larix spp.) are two species that could contribute to diversifying Ireland’s timber supply. However, there is little knowledge about their properties as well as their variation ... -
The influence of crown and stem characteristics on timber quality in softwoods
