Hot-pressing stress graded aspen veneer for laminated veneer lumber (LVL)
Holzforschung, 2005Abstract Aspen (Populus tremuloides) is emerging as an important species for laminated veneer lumber (LVL) products in North America. During LVL manufacturing, both veneer stress grades and hot-pressing schedules are vital to product performance.

Building and Environment, 2007
In this study the effects of steaming and drying condition on the mechanical properties and durability of laminated veneer lumber (LVL) and solid sawn lumber were investigated in a comparative way. Steamed beech and steamed and non-steamed spruce logs were used and two different veneer drying temperatures (20 and 110 °C) were selected for this aim ...

Engineering Structures, 2013
Abstract Holes in timber beams used as part of a floor system within a building are often required to allow services (such as electrical and plumbing) to pass through the beams. Cutting holes can initiate cracks that can propagate when beams are loaded, mostly because of low tension strength perpendicular to grain of timber. Crack propagation changes

EXPERIMENTAL INVESTIGATION OF THE EMBEDMENT STRENGTH OF LAMINATED VENEER LUMBER (LVL)
Sustainable Construction Materials and Technologies (SCMT)Connections in timber structures play a vital role in the stiffness, strength and overall performance of the structure. Embedment properties are of paramount to the overall performance of bolted connections. This study experimentally investigates the performance of embedment strength of LVL manufactured from Nordic Spruce (Picea Abies), utilising 10mm ...

An analytical model for design of reinforcement around holes in Laminated Veneer Lumber (LVL) beams
Materials and Structures, 2013Openings are usually required to allow services like plumbing, sewage pipes and electrical wiring to run through beams. This prevents an extra depth of the floor/ceiling, while preserving architectural considerations. The introduction of large opening causes additional tension perpendicular to grain in timber beams.

Fire Resistance of Connections in Laminated Veneer Lumber (LVL)
2006The fire resistance of timber connections is relatively unknown in the construction and design industries even though they are widely used. This research focuses on the fire resistance of nailed, screwed, bolted and self-drilling doweled connections in laminated veneer lumber (LVL) timber.

Analytical cracking load estimation of Laminated Veneer Lumber (LVL) beams with holes
European Journal of Wood and Wood Products, 2012Predicting the load-carrying capacity of timber beams with holes cannot be performed by usual analysis methods if the failure of the beam is governed by the crack initiation and propagation around the hole at low load levels. Predicting the cracking load is an important design issue because it corresponds to the load-carrying capacity of the timber ...

Impacts of some chemicals on combustion properties of impregnated laminated veneer lumber (LVL)
Journal of Materials Processing Technology, 2019The objective of this study was to investigate the effects of zinc chloride (ZnCl2) and borax (Na2B4O7.5H(2)O) on combustion properties of laminated veneer lumbers (LVLs) with two, three and four-layered, produced from white oak (Quercus alba) and chestnut (Cestanea sativa Mill.) woods. Veneers obtained for LVL were impregnated according to ASTM-D 1413.
