Modulus of Elasticity in Static Bending for Oriented Strand Board (OSB)

Creep response of engineered wood i-joist and oriented strand board (OSB) floor systems

Creep response of a full-scale floor system fabricated with composite wood I-joists and oriented strand board (OSB sheathing) was measured for 280 days at sustained uniform loads of 20 psf (0.96 kPa). Creep responses of bare I-joists and 3-joist T-beams with OSB sheathing (glued and unglued tongue and groove sheathing joints) were measured under similar load levels and duration. The creep defle...

Potential of Irish Orientated Strand Board in Bending Active Structures

To determine the potential of a low cost Irish engineered timber product to replace high cost solid timber for use in bending active structures such as gridshells a single Irish engineered timber product in the form of orientated strand board (OSB) was selected. A comparative study of OSB and solid timber was carried out to determine the optimum properties that make a material suitable for use ...

Relation Between Static and Dynamic Modulus of Elasticity of Wood

Static and dynamic modulus of elasticity (MOE) of spruce lumber were determined under different conditions like cross head speed, bending and longitudinal vibration, and mode numbers. The characteristic time of MOE determination is introduced. Characteristic time is defined as the typical MOE determination time. Shorter characteristic times are shown to result in higher MOE values. An order of ...

Differences in Dynamic Modulus of Elasticity Determined by Three Vibration Methods and Their Relationship with Static Modulus of Elasticity

Dynamic modulus of elasticity was determined in clearwood samples of eight tropical hardwood species using longitudinal vibrations, flexural vibration and ultrasonic transit-time methods. These samples were subsequently subjected to three point static bending test to determine static modulus of elasticity and modulus of rupture. Acoustic velocity and wood density were found to be independent pa...
