modulus of elasticity of composite wood decks

A. ASTM D-1413-99: Test Method for Wood Preservatives by Laboratory Soil-block Cultures, ASTM International. Establishing Performance Ratings for Wood-Plastic. Composite Deck Boards and Guardrail systems (Guards 1) Modulus of Elasticity (MOE): 542,200 psi.- Ultimate. 2) Modulus of Rupture (MOR): 3157 psi.

The concept of combining wood and concrete in layered composite bridge deck was investigated. A shear key anchor detail loading, a high degree of composite action was achieved in the beam specimens, as compared to use of ordinary .. Table 4.20 Summary of modulus of elasticity results for wood deck specimens .

Ultimate strength values are not meant for design 

Pound for pound, plastic and composites can't match the span capability of wood. "With either an all-plastic material or the wood-plastic composite materials, your strength is comparable to wood, but your stiffness, or flexural [elastic] modulus, is quite a bit lower," explains U.S. Army Corps of Engineers 

NOTE TO SPECIFIER Palram Americas, Inc.; Palram decking products. This section ASTM D-7032-04: Standard Specification for Establishing Performance Ratings for Wood-Plastic Composite Deck Boards and Guardrail systems (Guards or Handrails), ASTM International. . 1) Modulus of Elasticity (MOE): 204,000 psi.

DuraLife's Unique Polypropylene & Hardwood Composite Outperforms Other Wood and Composite Decking Products. A deck board's Modulus of Elasticity (MOE) and Modulus of Rupture (MOR) are good indicators of its ultimate performance and resistance to flex or sagging between joists. The higher the value, the better 

Common Uses: Boatbuilding, docks, decking, posts, fishing rods, pool cues, and other turned wood items. Comments: Greenheart is perhaps the stiffest wood in the world, with an average modulus of elasticity of an astounding 3,716,000 lbf in2! However, the wood also has a fairly high movement in service, and should not

manufacture of structural wood products, such as sawn lumber and glulam. In the broadest terms, trees and When closely packed, these wood cells form a strong composite system that is often compared to a bundle of .. properties are described by three elastic constants: modulus of elasticity. (E), shear modulus (G), and 

Evaluation of the Performance of Composite Wood Decking Bonded with Phenol Resorcinol Formaldehyde and Polyurethane Adhesives after Accelerated Aging Tests Compared with solid quartersawn decking boards, the quartersawn composite decking boards had the same modulus of rupture and modulus of elasticity.

Use of WPC lumber, either in the form of solid cross section or with tubular structure as shown in Figure 2, has been very popular material as a substitute for treated wood products. Table 1 also shows typical mechanical properties including modulus of elasticity (MOE) and modulus of rupture (MOR) of WPC. MOE and MOR 

Wood plastic composites weather the recession and questions about their weatherability.

This study measured the modulus of elasticity (MOE) of various plastics and composite materials with a Taber stiffness tester as an alternative to conventional universal testing machines. The proposed approach presents an expedited means to assess MOE for a wide range of plastics and wood plastic 

Wood-concrete composite floor deck systems are constructed by interconnecting a wood deck with a concrete slab . mechanical properties of wood; (ii) the unshored beams exhibited larger elastic deflection and slightly larger MOE for wood and concrete, and for the slip modulus of the notched connection. The histories 

A life cycle assessment (LCA) of alkaline copper quaternary (ACQ)-treated lumber in comparison to wood plastic composite (WPC) decking shows that the latter The properties studied were the modulus of elasticity (flexural modulus), flexural strength, compressive strength parallel and perpendicular to the grain, tensile
