Reinforced Timber Laminated Veneer Lumber (LVL) Connection Loaded Perpendicular to the Grain
… 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 joints, and …

Measurements of B(Ds -> lvl) and fDs using data collected from the BaBar experiment
… measurements of the branching fractions B(Ds -> lvl) and measurements of the pseudoscalar decay constant, fDs , using all the data acquired at the BaBar detector at SLAC National Accelerator Laboratory, which were collected from September 1999 to April 2007, and comprised 531 fb-1. The following …

Modeling of laminated veneer lumber - A study of the material properties for thick structural elements
… material properties of laminated veneer lumber (LVL). LVL is a timber product made of thin veneers of wood, glued together to form a laminate. The work has been carried out with the aim of providing a better understanding of LVL when designing large structures, in particular the thesis is related …

Investigation of Single and Two Bolt Connections Perpendicular to Grain in Laminated Veneer Lumber
… bolted connections for laminated veneer lumber (LVL) from different manufacturers. Comparison of the experimental results with the predicted results from three models: Technical Report -12 (AF&PA 1999), Van der Put and Leijten (2000) and Jensen et. al. (2003), for single and two bolt connections …

Measurement of elastic properties of silicates at realistic mantle pressures
… however, a 5-10 km thick low velocity layer (LVL) has been inferred to exist along the top surface of the subducting slab at depths of up to 250 km. Shear-wave velocities, in particular, within these layers have been estimated as up to 10% slower than in the surrounding mantle. High-pressure …

Serviceability Design of Long-Span Timber Beams Considering Semi-Rigid Beam-Column Connections
… deflection to end connection rigidity across 39 LVL and glulam beam sections with spans ranging from 4 to 12 m. The results demonstrate that incorporating connection stiffness in deflection calculation has a pronounced influence on beam design, particularly for spans exceeding 6 m, where …

Comparison of Shear Modulus Test Methods
… (MSR) lumber and laminated veneer lumber (LVL) to determine if the shear properties evaluated by the different test methods were equivalent. Measured E:G ratios were also compared to the E:G ratio of 16:1 commonly assumed for structural wooden members. The average shear moduli results …

An investigation of FRP reinforced glulam bolted connections
… of FRP reinforcement in Laminated Veneer Lumber (LVL) bolted connections under double shear loading. The FRP investigated consists of uniaxial carbon fibers embedded in a two-part epoxy. Sixteen sample wood connections were tested. Eight samples were reinforced with FRP such that the carbon fibers …
