    • An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce 

      O'Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (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 ...
    • Influence of connection systems on serviceability response of CLT timber flooring 

      Uí Chúláin, Caitríona; Sikora, Karol; Harte, Annette M. (TU Verlag Wien, 2016-08-22)
      In this paper finite element analysis of a five layer cross-laminated timber (CLT) rectangular floor is presented. The model was developed using 3D shell elements with linear elastic orthotropic material properties. Support ...
    • The influence of panel lay-up on the characteristic bending and rolling shear strength of CLT 

      O'Ceallaigh, Conan; Sikora, Karol; Harte, Annette M. (MDPI, 2018-08-21)
      The objective of this study was to characterise the behaviour of cross laminated timber (CLT) panels and the influence of the panel lay-up on the failure strength. Three different panel configurations of thickness, 60 ...
    • An investigation of the viscoelastic creep behaviour of basalt fibre reinforced timber elements 

      Conan O'Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (Elsevier, 2018-08-01)
      An investigation was carried out to examine the effect of flexural reinforcement on the long-term behaviour of timber beams. Creep tests, utilising statistically matched groups, were performed under Service Class 1 conditions ...
    • The mechano-sorptive creep behaviour of basalt FRP reinforced timber elements in a variable climate 

      O'Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (Elsevier, 2019-09-25)
      The use of Fibre Reinforced Polymer (FRP) reinforcement has been shown to improve the short-term flexural behaviour of timber elements. This is particularly important when reinforced elements are subjected to a variable ...
    • Viscoelastic creep in reinforced glulam 

      O'Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (TU Verlag Wien, 2016-08-22)
      The mechanical and physical properties of softwood timber can vary considerably as a result of the age and rate of growth of the tree and other environmental factors which affect the wood cell density and strength [1]. ...
    • Viscoelastic creep of FRP reinforced glulam 

      O’Ceallaigh, Conan; Sikora, Karol; McPolin, Daniel; Harte, Annette M. (NUI Galway, 2016-08-29)
      The reinforcement of timber using fibre reinforced polymer (FRP) rods or plates is widely accepted as an effective method of increasing the strength and stiffness of members, while at the same time reducing the variability ...
