mode shape curvature ratio

基本解釋

In this paper, based on the analysis of preceding research, a parameter, called mode shape curvature ratio, is put forward for damage identification of reinforced concrete framed structure.
本文在分析以往研究成果的基礎上，找到了一個基于曲率模態(tài)的對鋼筋混凝土框架結構損傷識別有效的參數(shù)——振型曲率比。
In this paper, based on mode shape, the author put forward a new parameter-mode shape curvature ratio for detecting structure damages. And it is also the input vector of the neural network.
本文基于模態(tài)振型，提出一個新的用于結構損傷識別的參數(shù)——振型曲率比，并將之作為神經(jīng)網(wǎng)絡的輸入向量。

振型曲率比
In this paper, based on the analysis of preceding research, a parameter, called mode shape curvature ratio, is put forward for damage identification of reinforced concrete framed structure.
使用該參數(shù)僅需得到結構損傷前后的第一階模態(tài)振型,然后計算出結構的振型曲率比,就可以據(jù)此識別出結構的損傷位置,并可以大致判斷損傷程度。
