Abstract:	在本論文中我們利用LS-DYNA有限元素軟體來進行計算，分析柱體受擾動外加位移，在計算時輸入具體的材料及幾何性質，研究柱體破壞時，利用外力和柱子反應紀錄來進行分析，再觀察關係圖的形狀，看是否有異常的趨勢，來判定柱子是否瀕臨破壞，而只要在某些破壞發生前能計算出有用的預警資訊就算滿意。以本文的兩個例子而言這樣的分析是會得到有用的結論。但未來應該仍要研究更多的例子才知道目前的方法是否具有高的成功率。 We use the LS-DYNA finite element program to calculate and analyze the failure of two structures. By analyzing the relation between the inputs and outputs of the structures . We try to find out the precursors of failure. The precursors are usually represented by some abnormal tendencies of the input-output relations.
