Abstract:

The purpose of the study was to search external features of timber useful for predicting modulus of rupture (MOR) and modulus of elasticity (MOE), both in axial direction bending, valid for a wide range of beam qualities. For the study, 23 European oaks (Quercus robur L.) were felled in northwestern Spain, where most of the oak stands in the country are located. The trees were sawn and a sample of quarter-sawn planks was selected. Planed and edged specimens (5×10×200 cm) were tested to obtain MOR, MOE, apparent density, wood moisture content, percentage of sapwood, ring width, slope of grain a

Abstract:

On the basis of research of quality indicators features of formation of surface of band saws are considered, prepared under various schemes of teeth set. In a study of process of sawing of timber on bandsaw equipment factors are defined which have the greatest impact on the quality of sawn timber, depending on the wood: hardwood (oak) and softwood (pine). According to the research regression models are obtained allowing calculating the optimal modes of band equipment to ensure the required quality of sawn obtained timber.

Round timber is often used for hydraulic engineering works, but the strength grading of round logs is not as well developed as that of sawn timber. The advantages of using defined strength classes, as well as the proper selection of the raw material, could be applicable to hydraulic works as well. In this study, the methods and rules developed for sawn timber were applied to the mechanical selection of oak round logs, paying particular attention to the issue of the simplicity of grading operations and the moisture content of the timber.

Engineered wood products, such as glulam beams, attract much attention from the building industry in recent years. Therefore, there is a constant necessity to seek new models of structural beams, which assume the use of outsized sawn wood pieces as an alternative for the standard construction timber. Three variants of glulam beams, composed of the main yield and side boards arranged in various structures, were proposed. Moreover, the usefulness of wedge-jointed, small-sized timber pieces was also investigated. The manufactured beams were tested, in terms of their mechanical properties, such as

Abstract Logging residues were inventoried in a 14-county region of southern West Virginia during the summer of 2002. A total of 70 sites that were harvested in 2000–2001 were sampled. The average overall weight of wood residue left after harvest in the region was 10.4 tons per acre (T/ac). Oak (Quercus spp.) was the most prevalent species group by weight, averaging 5.0 T/ac over the study area. Miscellaneous hardwoods, yellow-poplar, and maple species (Acer spp.) followed the oaks with 2.7, 1.2, and 1.2 T/ac, respectively. The average large-end and small-end diameter of the pieces measured on

This article presents the operation of an automatic pine sawn timber inspection system, which was developed at the Woodinspector company and is offered commercially. The vision inspection system is used to detect various wood defects, including knots, blue stain, and mechanical damage caused by worms. A blue stain is a defect that is difficult to detect based on the color of the wood, because it can be easily confused with wood defects or dirt that do not impair its strength properties. In particular, the issues of detecting blue stain in wood, the use of artificial neural networks, and improv

Abstract:

While it has been established previously that the strengths of commercial timber products containing knots and other natural growth characteristics are greatly influenced by the physical dimensions of the pieces, it has not been established whether the same is the case for defect-free wood. The structural engineer has a choice of many grades of timber available for his designs and it may be argued that these grades form a stepwise progression from the rather weak No. 3 grade through select structural grade and into clear defect-free sawn wood. For efficient design, it is important to have the

This article deals with the testing of a methodology for creating log cutting patterns. Under this methodology, programs were developed to optimize the log yield. Testing was conducted by comparing the values of the proportions of the individual products resulting from an implementation of the proposed cutting pattern of a specific log with the calculated values of these proportions of products using the tested methodology. For this test, nine pieces of logs (three pieces of oak, three pieces of beech and three pieces of spruce) were chosen, and then the proposed cutting pattern was applied on

The values of both the static and dynamic friction coefficients were determined, as this knowledge is of interest for the numerical simulation of the stress transmission in joints of timber structures. Therefore, two sets of tests were carried out combining different orthotropic orientations. Firstly, timber-to-timber tests were assessed to obtain the coefficients applicable to carpentry joints; secondly, timber-to-steel friction was also evaluated to determine the coeffic

Ring width variability affects the elasticity and strength of wood members. This study was conducted to determine which dispersion statistics of annual ring width distributions measured in cross section in European oak (Quercus robur L.) wood beams are useful as covariates in models for predicting modulus of elasticity (MOE) and modulus of rupture (MOR). For this purpose, 21 European oak trees growing in north-western Spain were felled, logged and sawn. The planks obtained were air-dried and surfaced into beams (50×100×2,000 mm), which were visually graded according to the UNE 56544:2022 stand

TCC is a structural system where timber beams and concrete slabs are combined to form a composite material, resisting tensile stress and compressive stress, respectively. The addition of concrete slabs protects timber beams from direct contact with water, which is crucial to ensure the durability of timber beams. Different types of connectors can be used to provide force exchange between concrete slabs and timber beams. This research wa

Abstract In order to obtain high production rates of sawn timber, the sawmilling industry can use laser scanning, allowing knot detection and machine strength grading. In particular, laser scanners measure grain angle using the so-called tracheid effect on wood surface where an elliptic scattering of the laser light can be observed. This paper aims to describe the light scattering obtained by a laser beam projection on wood surface and to assess the accuracy of such fiber orientation measurement on five European species.

However, as our everyday lives, identities, relationships, and embodiments become digitised and datafied, ‘wellbeing’ has taken on new practices and meanings. The use of digital technologies such as mobile and wearable devices, social media platforms, and networks of information mediate our interactions with others, as well as the ways we conceptualise what it means to be
