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(chǔ)上，找到了一個(gè)基于曲率模態(tài)的對(duì)鋼筋混凝土框架結(jié)構(gòu)損傷識(shí)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(gè)新的用于結(jié)構(gòu)損傷識(shí)別的參數(shù)——振型曲率比，并將之作為神經(jīng)網(wǎng)絡(luò)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(jié)構(gòu)損傷前后的第一階模態(tài)振型,然后計(jì)算出結(jié)構(gòu)的振型曲率比,就可以據(jù)此識(shí)別出結(jié)構(gòu)的損傷位置,并可以大致判斷損傷程度。
