雖然目前在學術界已經有許多柱基板接頭區之往復載重試驗與分析的研究存在，但是大多數的研究之力學行為不夠真實，因此本論文將進一步探討柱基板的往復側推行為。
本文將以有限元素法探討：柱基板之厚度、混凝土基座大小、錨栓之有效埋置深度以及軸壓力大小，對於弱柱-強接合型暴露式柱基礎的鋼柱初始勁度、遲滯迴圈面積以及接頭區旋轉勁度之影響。研究結果顯示，基座尺寸若過小、錨栓埋置深度過淺皆會造成混凝土基座產生脆性破壞，模型提前失敗，使得所有行為指標還未發展完全；較薄的柱基板較易產生面外變形，則鋼柱初始勁度、遲滯迴圈面積以及接頭區旋轉勁度皆會下降；有軸壓力施加之模型，相較於沒受到軸壓力影響之模型，其鋼柱塑性消能能力會大增，且旋轉勁度亦會提升。

There are lots of research studies about column base plate under cyclic loading, however, the loading conditions of most of them are not real enough. Hence, this paper will explore further about the behavior of column base plate under cyclic loading.
Here are the topics that will be analyzed by finite element program: the depth of the base plate, the pedestal size, the effective embedment of the anchor rods and the magnitude of the axial compressive force exerted on the top of the column; it will discuss how the factors affect the initial lateral stiffness and the hysteresis loop of the column, and the rotational stiffness of the connection. The analysis results indicate that if the pedestal size is too small, the effective embedment of the anchor rod is not large enough, or the using of thinner base plate will lead all the behaviour of the structure decrease. The larger axial force exert on the column, and the hysteresis loop area and the rotational stiffness increase.
