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 ...
Reinforcement of timber elements in compression perpendicular to the grain using compressed wood dowels
(National University of Ireland Galway, 2020-08-27)
ABSTRACT: In the past decade, there has been an increased focus on the environmental impacts of construction and a movement
towards more sustainable construction products. Timber is one such sustainable product that can ...
Recovered wood as raw material for structural timber products. Characteristics, situation and study cases: Ireland and Spain
(International Society of Wood Science and Technology (SWST), 2020-07-12)
The circular economy is an efficient system to reuse materials reducing the amount of waste generated. In order to implement it in the timber sector, the InFutUReWood (Innovative Design for the Future Use and Reuse of ...
Use of nondestructive techniques for determination of tension parallel-to-grain properties of spruce
(USDA Forest Service Forest Products Laboratory (FPL), 2019-09-25)
The paper presents a study of the tension properties of Irish-grown Sitka spruce. Fifty timber pieces were destructively tested having resonant frequency and knots measured. The aim was to improve knowledge of the performance ...
Numerical study of FRP reinforced timber members subjected to variable climates
(SHATiS International Conference on Structural Health Assessment of Timber Structures, 2019-09-25)
The use of FRP reinforcement, even in small percentages, has been shown to improve the short-term flexural behaviour of timber members. This technology has been successfully used in new construction and in the repair and ...
Flexural reinforcement of glue-laminated timber beams using prestressed FRP plates.
(NetComposites Limited, 2009-09-01)
Fibre-reinforced polymer (FRP) plates have been used successfully to enhance the structural performance of glue-laminated (glulam) timber beams. Unreinforced glulams usually fail in tension in a brittle fashion. The addition ...
Test machine effect in the determination of modulus of elasticity for strength graded timber
(World Conference on Timber Engineering (WCTE2021), 2021-08-09)
This paper investigates if the relationship between the global and local moduli of elasticity (MoE), measured in bending tests, is affected by the test machines employed, and how that may influence strength grading. The ...
Characterisation of Irish-grown Scots pine timber for structural applications
(Civil Engineering Research in Ireland, 2020)
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 ...
