Charring Rates for Different Cross Sections of Laminated Veneer Lumber (LVL)
2010Current research at the University of Canterbury is investigating the performance of a new type of timber floor system made of a timber-concrete composite. This newly proposed timber floor system uses double LVL members connected together with screwed connections to form one larger LVL member. Recent large scale fire tests showed that the joint between

"Design of reinforcement around holes in laminated veneer lumber (LVL) beams"
2012Many practical situations require holes in timber beams. When the hole is large relative to the depth, the failure of the beam is governed by crack initiation and propagation around the hole. Cracking of a timber beam decreases the capacity of the beam considerably.

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.

Synthesis of phenol formaldehyde (PF) resin for fast manufacturing laminated veneer lumber (LVL)
Holzforschung, 2018AbstractPhenol formaldehyde (PF) resin is a well-tried adhesive for manufacturing laminated veneer lumber (LVL). PF has a high bonding strength, good cold pressing property and contributes a lot to the high production efficiency of LVL. In the present paper, PFs were synthesized at three different alkaline condition levels with a molar formaldehyde to ...

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

Holding Performance of Dowels in Solid Wood and Laminated Veneer Lumber (LVL)
2015Bu çalışmada, farklı ağaç türlerinden hazırlanan lamine malzemelerin(LVL), liflere dik ve paralel doğrultudaki kavela tutma mukavemetleri, masif ağaç malzemelerle karşılaştırmalı olarak incelenmiştir. Deney örnekleri, Türkiye mobilya endüstrisindeki yaygın kullanımları nedeniyle Doğu kayını (Fagus orientalis Lipsky), Sarıçam (Pinus sylvestris L.) ve ...

Reinforced Timber Laminated Veneer Lumber (LVL) Connection Loaded Perpendicular to the Grain
The thesis reports the outcomes of a comprehensive study on how bolted timber connections with Laminated Veneer Lumber (LVL) respond to loading that is perpendicular to the grain. It investigates the topic in three main sections: understanding the stress-strain characteristic of LVL, checking how much splitting failure occurs in unreinforced bolted ...openaire +1 more source
Fire Resistance of Epoxy-grouted Steel Rod Connections in Laminated Veneer Lumber (LVL)
2004Epoxy-grouted steel rods are becoming increasingly popular for connections in structural timber in glue-laminated timber (glulam) and laminated veneer lumber (LVL). This research focuses on the fire resistance of these connections in LVL timber. These connections have been found to have high strength under service temperatures, but epoxy is known to ...
