現有之柱基板抗彎矩設計僅考慮作用於單軸下的影響，無雙向設計之考量，且對於規範設計出之柱基板板厚是否能如預期產生韌性行為有些許疑慮，因此本論文將討論新設計板厚的影響與雙向抗彎矩設計的檢核方式。
本論文將以有限元素分析軟體探討：柱基板厚度、錨栓大小與數量、加勁版設置與雙向抗彎矩設計的影響。由先前文獻中歸納出之韌性行為，新設計準則可使柱基板產生一定的塑性行為，並成功應用在雙向抗彎矩設計上。

Current design of column base plate only considers the effect of axial load and uniaxial bending. Some concerns have also been expressed as to the possibility that base plates designed by current code may behave more rigidly than expected. Hence, this paper will discuss the effect of new design method and propose biaxial bending design method.
Here are the topics that will be analyzed by finite element program: thickness of base plate, the size and amount of anchor rod, stiffer and the effect of biaxial bending with axial load. Based on the previous researches, the base plate in new design method will develop certain plasticity with some yield zone in column, which is a better ductile behavior comparing with the design of current method, and can be successfully applied to new biaxial bending design method.
