潛變是混凝土是重要的力學特性之一，在固定載荷下的混凝土構件的變形隨時間而增加，靜不定的結構會產生內力重新分配，所以在設計鋼筋混凝土結構時應當考慮潛變的影響。然而目前關於潛變的研究大多集中在純混凝土構件的力學行為，而對於含潛變效應鋼筋混凝構件的數值模擬相對較少，本文主要說明如何用向量式有限元素法進行含潛變效應鋼筋混凝軸力構件的力學模擬，最後以簡單算例說明向量式有限元素法(Vector Form Intrinsic Finite Element Method , 以下簡稱VFIFE)模擬含鋼筋混凝土構件潛變行為的可行性。;Creep is one of important mechanical characteristics of concrete, its deflection increases with time under a constant loading condition and will induce force redistribution in statically indeterminate structures. Hence, the influence of creep should be considered in the design of reinforced concrete structures. Nowadays, most of the studies on creep are focused on the mechanical behavior of pure concrete members, numerical simulations of reinforced concrete member with creep effect are still relatively few. In this study, Vector Form Intrinsic Finite Element method (VFIFE) are used to analyze the mechanical behaviors of reinforced concrete axial member with creep effect. Finally, illustrative examples are provided to show VFIFE can be applied to simulate reinforced concrete creep behavior.
