摘要: 
The stress-wave momdestructive test (NDT) me thod was applies in this
research to test the joint strength of T-type joint and try to predict the
joint defect. The relationship of joint strength predicted by NDT and tested
by traditional destructive

本研究主要以應力波非破壞性測定法,檢測3種T型接合構件之接合強度,及預測
構件缺點之可行性,並比較其他與傳統破壞性檢測接合強度之相關性。試材加工前後之波速
並沒有明顯的差異,但構件組合後橫檔之波速會變慢;以打音頻譜分析系統檢測構件縱向振
動頻率時,抗彎構件中兩種針葉樹材彎曲接合構件之振動頻率平均比兩種闊葉樹材低約 30%
。4 種樹種的接合構件引拔強度以紅櫟木 (Qrercus spp.) 最大 (1552kgf),美國西部鐵杉
最小 (Tsuga heterophylla Sorg.)(577
