Round Small-Diameter Timber for Construction. Final Report of Project FAIR CT 95-211 0091

摘要

The use of small-diameter timber in construction has been investigated. The aim211u001eof the work is to increase the use of the wood harvested in forest thinning in 211u001econstruction applications. The work has covered a wide range of aspects, from 211u001eavailability of the material to design of the structures. This publication 211u001esummarizes the results in following areas: availability, dimensions and quality 211u001eof conifers harvested in forest thinning, cost of harvesting and woodworking, 211u001ecomparison of drying methods; seasoning, warm-temperature and high-temperature 211u001ekiln-drying, improving durability, strength of round small-diameter confiers, 211u001epotential types of structures to be built from round timber and new mechanical 211u001ejoints. The tree species that were included in the study are Scots pine, Norway 211u001espruce Sitka spruce, Larch and Douglas fir.
