Viscoelastic creep in reinforced glulam
(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]. ...
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 ...
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 ...
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 ...
