The effect of thinning on mechanical properties of Douglas fir, Norway spruce, and Sitka spruce
(Springer Verlag, 2019-01-07)
Context: The relationship between silvicultural management and the quality of timber produced is not entirely elucidated.
Aims: The effects of thinning on structural grade-determining properties of wood (elastic modulus, ...
An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce
(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 ...
Timber grading potential of Douglas fir in the Republic of Ireland and the UK
(Taylor & Francis, 2019-05-19)
Results of the recently approved machine control grading settings for Douglas fir in the Republic of Ireland and the UK have shown that the species can be graded to C18, and higher strength classes, and while there is a ...
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 ...
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 ...
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 ...
Relationships between wood properties of small clear specimens and structural-sized boards in three softwood species
(De Gruyter, 2019-06-12)
Research on the mechanical and physical properties of wood is commonly carried out on either small clear specimens or structural-sized boards. The first approach was more frequently utilised in the past, while the latter ...
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 ...
The mechano-sorptive creep behaviour of basalt FRP reinforced timber elements in a variable climate
(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 ...
