摘要

本研究的目的是研究榫卯连接对木制构件杨氏模量的影响，并提出杨氏模量的校正方法。通过纵向振动试验，获得了两个附加集中质量(cm)试件和榫、榫连接试件的杨氏模量。实验证明了附加两个cm的试样纵向振动的频率方程。将榫卯结合的试件作为矩形棒材处理时，杨氏模量最大偏差为17%。质量比(榫头和榫头的质量/主体的质量)和体积比(榫头和榫头的体积/主体的体积)可用于上述频率方程。使用这种方法，可以准确地估计建筑工地上带有榫卯的木制构件的杨氏模量。

Determining Young’s Modulus of Wooden Members with Tenon and Mortise Joint Using Longitudinal Vibration

The aim of this study was to examine the effect of tenon and mortise joints on Young's modulus of wooden members and propose a correcting method of Young's modulus. Young's moduli of the specimens with two additional concentrated masses (CMs) and those of the specimens with tenon and mortise joints were obtained using the longitudinal vibration test. The frequency equation for the longitudinal vibration of a specimen with two additional CMs was experimentally proved. The maximum deviation of 17% in Young's modulus was observed when the specimens with tenon and mortise joints were treated as rectangular bars. The mass ratio (mass of a tenon and a mortise/mass of the main body) and the volume ratio (volume of a tenon and a mortise/volume of the main body) could be used for the aforementioned frequency equation. Using this method, it is possible for one to accurately estimate Young's modulus of a wooden member with a tenon and a mortise on a construction site.
