摘要

本研究探討過盈配合條件下，榫頭與榫孔構件水份差、附加插梢與佈膠等因素對木構件方榫接合彎矩之影響。得到結果歸納於次：1. 就水份差條件觀之，未佈膠與未附插梢構件之接合彎矩較其他構件增大14.3%~22.5%。2. 就附插梢條件觀之，佈膠構件之接合彎矩會大於未佈膠構件47.0%~70.0%。3. 就未附插梢條件觀之，佈膠構件之接合彎矩會大於未佈膠構件110.1%~171.9%。4. 就未佈膠條件觀之，附加插梢對未佈膠構件之接合彎矩可增大15.4%~48.9%。

This study is aimed to discuss under the condition of interference fit, how the factors of moisture difference, pin attachment and glue affect the bending moment of mortise and tenon joints. The conclusions are listed as follows: 1. Under the control of moisture difference, the bending moment of wood members without glue and pin attachment is 14.3% to 22.5% larger than others. 2. Under the control of pin attachment, the bending moment of glued members is 47.0% to 70.0% larger than those of unglued ones. 3. Under the control of without pin attachment, the bending moment of glued members is 110.1% to 171.9% larger than those of unglued ones. 4. Under the control of without glue, the bending moment of wood member with pin attachment is 15.4% to 48.9% greates then those unglued members.
