通过加速腐朽试验探讨腐朽木构件力学性能的退化规律。设计制作6组,每组10个大尺寸油松木构件试样,进行了为期6个月的加速腐朽试验,并分别测试了加速腐朽1,2,3直至6个月的木构件的抗弯强度、顺纹抗压强度及弹性模量等力学性能,确定了在加速腐朽环境下木构件的强度退化模型。 Deterioration of Mechanical Properties of Rotten Wood Components by Accelerated Decay Test. Six groups of 10 large-size oil-pine wood samples were designed and manufactured. Accelerated decay tests were conducted for 6 months. The flexural strength of wood components accelerated for decayed 1, 2, 3, up to 6 months were tested separately , The compressive strength of the grain along with the mechanical properties such as elastic modulus, determine the intensity degradation model of wood components under accelerating decay environment.
