Proceedings pro008 : International RILEM Symposium on Timber Engineering

Title: International RILEM Symposium on Timber Engineering Edited by L. Boström ISBN: 2-912143-10-1 e-ISBN: 2351580230 Pages: 860 Publication date: 1999

The aim of this RILEM symposium was to present the latest research results in the field of timber engineering, ranging from basic research of wood mechanics to preservation of old buildings and the cultural heritage.
Wood is a renewable resource that can be supplied on a sustainable basis and is formed under singularly ecological conditions.
At the same time forests provide a number of unique and varied benefits that include protection of our climate, water and soil and a great range of recreational functions enjoyed by the general public.
Wood can be produced without adverse effects on the environment and can be worked, put to a great number of uses and disposed of with little energy. Wood fulfils all the technical demands made on a modem building material.
Hence, the forest products industries, in active co-operation with architects and engineers are called upon to make use of thefull potential of wood and to advance its use in construction. The ecological advantages of wood as a building material will contribute a great deal towards improving the future of one and all.
