Statistical analysis of properties of timber species for structural use

Abstract

This study investigated the physical and mechanical properties of two Nigerian timber species- Azadirachta indica and Xylopia aethiopica for structural use. Three logs of each species were obtained at different locations of the country, seasoned naturally and their structural strength properties were determined and converted to strength at moisture content of 18%. These logs were cut into specimens to facilitate the determination of the properties of the timber. A total of 45 specimens for each property, free from visible defects were used. Basic physical properties of the samples like moisture content, specific gravity and density.
