論文中文摘要:現今評估鋼筋混凝土柱的極限破壞一般是採用反覆載重試驗(cyclic loading test)所得遲滯迴圈中,其最大側向力之80%來定義。由於鋼筋混凝土試體具有明顯的遲滯消能特性,因此本論文從能量消散的觀點來重新定義鋼筋混凝土的極限破壞。能量消散法係以單位位移內之最大消散能量點來定義極限破壞,其中每一遲滯迴圈所消散的能量係以指該迴圈所包圍的面積,並將每一遲滯迴圈所包圍的面積除以該循環推拉兩側的最大位移量之和,可得一單位位移消散能量容積圖,當單位位移所能消散的能量達到最大值時,認定試體達到極限狀態。為了證實本論文所提出的能量消散法之可行性,搜集了許多的反覆載重實驗資料,分別使用現今一般慣用的評估方法以及本論文所提出的能量消散來評估鋼筋混凝土試體之極限破壞。
論文英文摘要:The 80% maximum lateral force of hysteresis loops, which is obtained from a cyclic loading test, is often used to define the ultimate failure state of a reinforced concrete specimen. In this study, the ultimate failure state for a reinforced concrete specimen is characterized by the concept of a cyclic energy dissipation rate since a reinforced concrete specimen usually displays hysteresis energy dissipation. In fact, the ultimate failure state is defined as the maximum value of the cyclic energy dissipation per unit length, which is obtained from the total energy dissipated in a cycle divided by the sum of the maximum imposed displacements in both the push and pull directions of the corresponding cycle. To confirm the appropriateness of the proposed definition of the ultimate failure state, the data of cyclic loading test results were collected and analyzed to obtain the ultimate failure state for each specimen. In general, both methods can provide a good correlation in determining the ultimate displacement and thus ductility.
