論文中文摘要:混凝土已普遍應用於土木工程的各個領域,隨著土木工程技術的進步,混凝土結構安全性的檢測已日益重要,近年來隨著材料技術的研究開發,高性能感測材料不斷被使用在土木工程結構的檢測中,例如壓電材料、碳纖維材料等,應於土木結構上的診斷材料應具備材料成本低、良好耐久性及穩定性、高靈敏度的特點。碳纖維材料是一種可應用於土木結構檢測的感測材料,當碳纖維混凝土受壓縮或拉伸時,因碳纖維本身之拉伸或壓縮會造成其電阻之變化,拉伸會造成電阻值減小,反之壓縮則造成電阻值增大,如此則可藉由量測電阻方式來測得試體在受力下之變形程度。本文以不同加載速率與不同加載次數來進行實驗,並比較不同加載方式對試體電阻變化之影響,本實驗採一般碳纖維混凝土圓柱試體,其量測方式以二線式進行量測,由試驗結果顯示,當加載速率越快,在相同應變下其電阻變化率將會越小,反之則越大;而加載次數對電阻變化率之影響則較不明顯。
論文英文摘要:Concrete has been widely used in various fields of civil engineering in many decades, and the health monitoring of the concrete structures has become more important in recent years. The high-performance sensing materials continue to be adopted in the monitoring and sensing of civil engineering structures, such as the piezoelectric material and carbon fiber material, etc., the suitable materials for applying to the civil engineering should have the features of low cost, well durability and stability, and high sensitivity. Carbon fiber material is one of the sensing materials that can be applied to the monitoring and sensing of civil engineering structures. When the carbon fiber concrete specimen subjected to the applied loads, the stretch or squeeze of the carbon fiber itself will cause the change of resistivity of the specimen, therefore, this properties can be applied to measure the deformation of the concrete specimen by measuring the change of the resistivity. In this research, the main purpose is to discuss the influence of the loading rate and cycles of loading to the fractional change of resistivity of the carbon fiber concrete. The test results show that the change of resistivity decreased as the loading rate increased under the same loading, and the influence from the cycles of loading is not very obviously.
