Spatial Variability of Ozigo Wood Beams under Long-Term Loadings in Various Environmental Exposures

Timber is a renewable material that should be more used for sustainable construction. While the mechanical behavior and durability of some species have been widely studied in past, few studies are available Ozigo (Dacryodes buettneri) specie. This paper deals with spatial variability beams subjected to long-term loadings different environmental conditions. These were previously creep three environments (air-conditioned, unsheltered, sheltered) at Masuku south-east Gabon. Various specimens extracted from these determine its moisture content three-point bending tests obtain modulus elasticity failure stress various points space. The results obtained showed that, after loadings, exposure combined loading, play key role properties timber beams. A reduction strength was found unsheltered sheltered outdoor exposures comparison those air-conditioned exposure. Concerning variability, statistical confirm there significant correlation. It also variation beam not stationary because it affected by loading support
