| dc.description.abstract | 木構造建築承受時間與外在環境條件影響甚鉅，易產生腐朽亦或裂縫成長等問題，其相關維護方式較無系統性之探討。為探討木材損傷後修補成效，本研究藉由商用有限元素分析軟體ABAQUS，搭配自行撰寫使用者副程式UMAT與DFLUX，分別描述木材組成律與木材表面水分傳遞模型，並採用延伸有限元素法與膠合損傷模型，模擬損傷修補相關行為。藉由木材拉伸試驗與扭轉剛性試驗獲致抗彎數值分析所需基本材料參數，損傷參數則藉由抗彎數值分析與抗彎試驗結果之力量-位移反應擬合獲得。將上述所得參數導入抗彎數值分析，進行三種開槽斷面形狀與三種開槽位置之填補前後抗彎數值分析，並與相對應統計後試驗結果進行比較，藉以檢視木材損傷修補流程之合宜性。 | zh_TW |
