Comparison of Lateral Load Performance of Light Wood Diaphragms Built with Sawn Lumber and Wood I-Joists

Journal of Materials in Civil Engineering, 2021
AbstractDiaphragm design provisions in North America were originally developed based on the performance of diaphragms constructed with sawn lumber framing members.

Lateral Torsional Buckling of Wood Beams

2014
Structural wood design standards recognize lateral torsional buckling as an important failure mode, which tends to govern the capacity of long span laterally unsupported beams. A survey of the literature indicates that only a few experimental programs have been conducted on the lateral torsional buckling of wooden beams.

Finite-Element Model for Wood-Based Floors with Lateral Reinforcements

Journal of Structural Engineering, 2004
Lateral reinforcements can enhance serviceability of wood-based floor systems. However, because of a lack of proper analysis models, the benefit from installing these components has not been fully recognized in floor design. In this paper, a finite-element model for predicting static and dynamic characteristics of wood-based floor structures with ...

Design properties of laterally loaded nailed or bolted wood joints

Canadian Journal of Civil Engineering, 1988
This paper summarizes the output from a long-term project commenced in 1980 with the objective of providing reliable knowledge of the mechanical properties of nailed or bolted joints subjected to short-term lateral loadings. Motivation was the development on an international basis of probability-based partial coefficients limit states design codes for

Lateral Resistance of Wood Shear Walls with Large Sheathing Panels

Journal of Structural Engineering, 1997
This paper summarizes results from the first phase of a study to evaluate the lateral resistance of wood based shear walls without openings, built with regular and nonstandard large dimension oriented strand board panels under monotonic and cyclic loading conditions. Furthermore, different types and spacings of panel-frame connectors were investigated.

Lateral Torsional Buckling of Wood I-Joist

2016
Engineered wood I-joists have grown in popularity as flooring and roofing structural systems in the past 30 years, replacing solid sawn lumber joists. Typical wood I-joists are manufactured with a very slender section, which is desirable to achieve higher flexural capacities and longer spans; however, this makes them susceptible to lateral torsional ...

Cross-field pitting characteristics of compression, lateral, and opposite wood in the stem wood of Ginkgo biloba and Pinus densiflora

IAWA Journal, 2020
AbstractThe characteristics of cross-field pitting among compression wood, lateral wood, and opposite wood, in the stem woods ofGinkgo bilobaandPinus densiflorawere investigated with optical and scanning electron microscopy. InGinkgo biloba, compression wood exhibited piceoid pits, while lateral and opposite wood exhibited cupressoid pits.

Lateral Performance of Nonsymmetric Diagonal-Braced Wood Shear Walls

Journal of Structural Engineering, 2009
The lateral performance of structurally nonsymmetric diagonal-braced wood shear walls used in post-and-beam timber buildings was investigated with laboratory testing and computer modeling. Monotonic and reversed cyclic tests were performed to study the capacities of a total of eight full-scale shear walls, with and without gypsum wallboard sheathing ...

Effects of lateral wood zone on brown rot resistance of untreated and linseed oil-impregnated Scots pine wood

European Journal of Wood and Wood Products, 2012
Various oils can be used to lower the equilibrium moisture content and increase the service life of Scots pine wood products. The aim of this study was to investigate effects of the lateral wood zone on the brown rot resistance of untreated and linseed oil-impregnated Scots pine wood in a laboratory test (EN 113).
