Characterisation of Irish-grown Scots pine timber for structural applications
(National University of Ireland Galway, 2020-08-27)
There is very little knowledge on the timber quality of the native Scots pine grown in Ireland, and its potential to produce timber for structural applications. This paper studied the mechanical performance in tension and ...
Mechanical characterisation of green Sitka spruce logs
(NUI Galway, 2016-08-29)
ABSTRACT: Timber is by its nature a very heterogeneous material. Many different factors impact its mechanical properties,
from tree species to environment (climate, competition, soil…). While a number of studies in the ...
Review of state of the art dowel laminated timber members and densified wood materials as sustainable engineered wood products for construction and building applications
(Elsevier, 2019-12-10)
Engineered Wood Products (EWPs) are increasingly being used as construction and building materials. However, the predominant use of petroleum-based adhesives in EWPs contributes to the release of toxic gases (e.g. Volatile ...
Experimental investigation of the serviceability behaviour of a cross laminated timber floor
(NUI Galway, 2018-08-29)
European timber design standards set out basic serviceability limit design criteria for single span, simply supported floors, but the rotational stiffness of the fixing system and two-way support possible with modern solid ...
Evaluation of the mechanical behaviour of novel latticed LVL-webbed joists
(Bentham Open, 2019-01-23)
The mechanical behaviour of a novel I-joist having a latticed Laminated Veneer Lumber (LVL) web is investigated. A total of 30 joists with C24 Grade flanges and latticed LVL webs were manufactured and tested to failure. ...
The elastic and ductile behaviour of CLT wall-floor connections and the influence of fastener length
(Elsevier, 2019-03-30)
An investigation was carried out to examine the influence of the fastener length on the elastic and ductile failure behaviour of typical steel-to-timber bracket connections in Cross Laminated Timber (CLT) manufactured from ...
Mechano-sorptive creep in reinforced glulam
(National University of Ireland Galway, 2018-08-20)
An investigation was carried out to examine the effect of reinforcement on the creep behaviour of FRP
reinforced timber elements in a controlled variable climate. Creep is accelerated by moisture variations due to a ...
Mechanical properties estimation by non-destructive testing of Irish hardwood round timber from thinnings for construction purposes
(Department of Forestry Policy and Economics, University of Sopron, Hungary, 2018-10-25)
Thinning involves the removal of competitors of high quality trees, and trees for extraction racks, all to favour the growth of the selected trees. Many felled trees are small-diameter and in Ireland hardwood thinnings are ...
Irish timber - characterisation, potential and innovation
(Civil Engineering Research Association of Ireland (CERAI), 2014-09-28)
In order to increase the utilisation of Irish timber in construction and novel engineered wood products, the mechanical and physical properties of the material must be established. For timber products used for structural ...
Enhancing low grade sitka spruce glulam beams with bonded-in BFRP rods
(National University of Ireland Galway, 2014)
The reinforcement of timber elements using fibre reinforced polymer (FRP) rods or plates
is widely accepted as an effective method of increasing the stiffness of members, while at
the same time reducing the variability ...
