The design strength (5th percentile) of the beams, obtained by Monte Carlo simulations, is reported and found to range from 32.3 MPa to 97.2 MPa, depending on the quality of the veneers used and the beam size. The LVL beams have design strengths comparable to, and in some cases up to ...
The collected data were used as input values to develop a numerical model to understand the delamination of SPG glulam beams when exposed to a wetting and drying process. Thus, Mode I and Mode II fracture energies for crack propagation along radial and glueline directions were experimentally ...
In LVL tensile experiment, the Maximum stress theory shows some difference compared to the actual data under 45°. Oh [31] considers that this is due to inaccuracy of shear stress. Conclusions 1. A uniaxial compression test of bamboo scrimber showed wrinkled failure at 0–10°, shear ...
The connection system has notches cut from the LVL joist and reinforced with coach screws to increase the shear strength and provide more ductile behaviour. These notches are cut in the beams before the plywood interlayer is nailed on. The outcomes of the experimental push-out test carried out ...
Let's be clear first that a significant concern with the strength of supporting stair stringers (effectively angle beams) arise because a typical 2x12" (or rarely 2x14") stringer is in some stair designed notched to carry the stair treads on the horizontal notch face and stair risers on th...
Non-destructive evaluation of adhesive bond strength in laminated wood beams: British journal of non-destructive testing, vol. 31, no. 12, pp. 675–679 (Dec. 1989) Acousto-Ultrasonic (AU) non-destructive evaluation of laminated wood beams has been conducted to evaluate the adhesive bond ...
LVL is more economic and aesthetic than solid woods. It can be used for production of furniture, cupboard, desk, chair, table, etc. building materials, column and beams [2]. Technological properties of the laminated cedar wood (Cedrus

Single-end notched beams and compact shear specimens were used to capture the Mode I and Mode II fracture energies, respectively. For crack initiation, the tensile strength perpendicular to the grain and the shear strength (taken as the maximum stress from the Mode II fracture tests) were also...
LVL comprising at least one treated veneer and having a cross-sectional profile similar to natural construction lumber can be used wherever construction lumber is used. Similarly, plywood comprising at least one treated veneer can be used in place of conventional plywood. Such uses of LVL and plyw...
