摘要

本研究探讨了温度和相对湿度如何影响加纳阿曼提亚和温尼巴杂交桉树木材的弯曲强度特性。根据 BS 373:1957，在不同温度和相对湿度水平下对六棵树的桉树木材进行了测试。研究测量了木材样本的弹性模量（MOE）、断裂模量（MOR）和含水率（MC）。结果表明，MOE 和 MOR 在不同的调节参数 N、T、K 和 G 下变化很大。根据木材与水的关系理论，MC 也会影响木材的机械强度特性。研究认为，气候和地理位置是评估杂交桉树机械性能时需要考虑的重要因素。这项研究对于优化桉树木材的利用，特别是在加纳三个不同气候区的建筑和相关行业的利用具有实际意义。

EFFECT OF TEMPERATURE AND RELATIVE HUMIDITY VARIATIONS ON BENDING STRENGTH PROPERTIES OF HYBRID EUCALYPTUS WOOD IN GHANA

The study examines how temperature and relative humidity affect the bending strength properties of hybrid eucalyptus wood from Amantia and Winneba in Ghana. Eucalyptus wood from six trees were tested based on BS 373:1957 under different temperatures and relative humidity levels. The study measured the modulus of elasticity (MOE), modulus of rupture (MOR), and moisture content (MC) of the wood samples. The results showed that MOE and MOR varied significantly across the different conditioning parameters N, T, K and G. MC also influenced the mechanical strength properties of the wood, following the wood-water relation theories. The study concluded that climate and geographical location are important factors to consider when evaluating the mechanical properties of hybrid eucalyptus. This study holds practical implications for optimizing the utilization of eucalyptus wood particularly in the construction and related industries in the three different climatic zones of Ghana.
