Wood Builders & Designers

< Home

This user group is for builders and designers who use tropical wood in construction, as well as the manufacturers of building joinery and architectural millwork products.

This user group will collaborate with specialized organizations worldwide to promote the use of well-dimensioned, dried and graded wood products in local and regional construction markets. It will support development and two-way trade of value-added products including prefabricated components and engineered products for the global construction trade.

ITTO seeks expressions of interest from local producer organizations and senior technical specialists to participate in the editorial panel for this user group. Please contact: Ramon Carrillo, carrillo@itto.int

  • ABC - Bending Strength MOR, Technology Keys - "The strength of wood samples in air dry condition (12% MC) is used for sorting and comparing species into the ranges  shown below. These ranges or Technology Keys were used by the original database. The Modulus Of Rupture in bending (MOR) is a rough estimate of the ultimate bending strength of timber based on defect-free samples  of 20x20 mm sized sample of the transverse section of a piece of timber. However, in practice the modulus of rupture and other strength properties of a piece of construction timber are influenced by many factors such as wood defects, moisture content, load position and duration, among other. So, this is NOT a design value. It is expressed in kilograms force per square centimeter (kgf/cm2). Low: Less than 580 (kgf/cm2) Medium: 581 up to 685 Fairly high:  686 up to 808 High: 809 up to 956 Very high: 957 up to 1160 Extremely high: Over 1161 (kgf/cm2) "
