營建支撐系統挫屈失敗檢測分析模式

An Analysis Model for Predicting the Buckling Failure of Supporting Systems Used In Construction

本文針對營建支撐系統挫屈行為的檢測，提出分析模式。分析原理係利用能量等值觀念，將作用桿件導致挫屈可能之軸向力，等值為垂直桿件之橫向力，並以動態實驗分析所得之振動參數配合柔度矩陣，以力法解得挫屈載重。

An analysis model for predicting the buckling load is developed for the supporting system in construction. The algorithm involves first the application of energy method to determine the transverse force which is equivalent to the axial load, and then the use of vibratory parameters that are determined experimentally, along with the flexibility matrix, to calculate the buckling load.
