壞程度隨著使用時間的增長而日漸擴大,間接地影響到結構物的使用
年限及功能。有鑑於此,在時間及財力等因素的考慮下,擬藉由補強
混凝土結構物之修補,必須選用適當的黏合材料作為黏著劑。為
了觀察維修後之成效,一般皆使用混凝土與黏合材料所構成之複合斜
剪試體來進行一切盡可能之參數的評估。在研究中擬以四種不同特性
之材料作為黏合材料,應用理想及硬化彈塑性模型以數值有限元素法
來作分析,藉由此種方法來了解斜剪試體在加載過程中之力學行為及
研究之參數包括黏合材料與混凝土間之相對勁度、黏結角度及黏
合材料之厚度等。主要的目的在於了解加載過程中,沿著黏結界面兩
側材料中之主應力分布;以及試體在加載過後所可能產生之破壞行
為。進而決定出適當的黏合材料及黏結角度之範圍。
