【 摘 要 】

The main purpose of this research paper was to determine the influence of the wood moisture on the strength and elastic modulus of pine and fir wood specimens subjected to the 4-point bending tests. Six bending tests for each wood species and for two different moisture level have been performed. Then, the advanced statistical analysis of the results has been carried out. On the basis of the obtained results, it has been noted that growth of the wood moisture significantly affects the reduction of the tested strength and elastic modulus. It has been noticed that the values of the bending strength of the wet specimens (the wood moisture approximately 29%) decreased by more than 40% in relation to the dry specimens (the wood moisture approximately 10%).
