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 theory predicts the ultimate bending moment capacity of beams, using compressive and tensile strength of the beam material. Experimental tests on 169 eastern spruce [Picea rubens] and Douglas-fir beams of five different cross-sectional dimensions, subjected to two methods of loading - central an...
The long-term loading strength of end-notched beams made of glulam and LVL was tested. The beams were of various sizes, with and without a moisture sealing... PJ Gustafsson,P Hoffmeyer,G Valentin - 《Holz Als Roh Und Werkstoff》 被引量: 52发表: 1998年 Experimental behaviour of high-stren...
(L W ). Considering the interaction of wood type and process, the bending strength was obtained from laminated Oriental beech, whereas the lowest was found for impregnated Uludag fir. In consequence, in the massive construction and furniture elements that the bending strength after the ...
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 ...

LVL production has increased from 275 million board feet in 1992 to over 1 billion board feet in 2002. The main applications for LVL are the flange material for I-beams and headers and beams in residential housing. An important advantage for LVL is the formation of an engineered material ...
Owing to the excellent strength-to-weight ratios, Laminated Veneer Lumber (LVL) becomes one of the favorable building materials for timber structures, especially for long-span structural beams. Attempts have been made to use high-yielding Chinese larch pine as a raw material of structural LVL, ...

Monte Carlo simulation model which uses beam theory, probability statistics, and statistical characterization of the mechanical properties of populations of laminations to predict the distributions of MOR and MOE of vertically glue-laminated beams of any species, grade, geometry, and number of ...
