Embedment Strength of Tropical Timber Species

Species independent strength grading of structural timber

Literature review of impact strength of timber

The use of timber in structures like guard-rail systems requires knowledge about the behaviour at high loading rates. The present study aims at presenting a state of art report with respect to the impact bending strength of timber and to some extent to the behaviour of timber joints at high loading rates. The literature review indicates a difference in the experimental results and the conclusio...

Control of timber strength grading machines

Procedures for the control of timber strength grading machines have been established, including both machine control and output control. For the machine control so called control planks have been developed which enables a dynamic control of the whole grading system, i.e. the grading machine as well as infeed and outfeed equipment. Some generic control plank designs have been developed which may...

Domestication of native tree species for timber plantations: key insights for tropical island nations

A review of tree domestication principles, practices and case studies illustrates the importance of a methodological approach to domestication. Domestication of new species involves of the entire value chain from identification of candidate species, through production and management, to uptake by communities and markets. Efforts to domesticate forest trees have often neglected the final step of...

Estimating Sustainable Timber Production from Tropical Forests

Natural forests in the humid tropics differ from temperate and plantation forests in several ways: there may be many tree species; many of these may occur infrequently; there may be a large range of tree sizes and shapes present; tree ages may be unknown and indeterminate; and despite the luxuriant appearance some rainforests, growth rates may be relatively low. This has many implications for t...
