Timber constructions as a main participant in the solution of housing problem

The development of timber constructions all around the world may be a very important component in a global policy of affordable housing. To realize this target timber constructions must have adequate security and acceptable durability. It means to have a well-founded Specific Structural Theory and sufficient data about deterioration process and rheological comportment. In this paper we analyze: a) the advantages and disadvantages of timber constructions; b) the main basic hypothesis to develop a theory concerning the “Strength of Wood Material Bodies” (a specific Strength of Materials referred to timber constructions); c) a more precise method to determine wood strength in any case; d) an adequate policy to assure desirable durability of timber constructions.
