STRENGTH AND STRUCTURAL PROPERTIES OF STRUCTURAL TIMBER
Journal Title: Structure and Environment - Year 2016, Vol 0, Issue 2
Abstract
Taking into account the growing significance of structural timber in the building industry, the paper aims at defining the selected mechanical and physical properties of the Polish pine structural sawn timber from four nature and forest lands: Land A – Mazovian-Podlasian Nature and Forest Land (Forest District Garwolin), Land B – Little Poland Nature and Forest Land (Forest District Przedbórz), Land C – Silesian Nature and Forest Land (Forest District Kedzierzyn Koźle), Land D – Carpathian Nature and Forest Land (Forest District Piwniczna)[4]. The paper presents the definition of timber, its macroscopic and microscopic structure as well as factors affecting the mechanical properties of timber such as moisture or structural defects. The conducted tests involved sorting sawn timber in terms of strength using visual method according to the PN-D-94021 standard as well as characterizing the average moisture of the fresh and artificially dried sortment [6-8]
