An improved method for structural damage identification based on residual force vector is presented. 提出了一種改進(jìn)的殘余力向量法用于工程結(jié)構(gòu)損傷識(shí)別。
Despite the fact that damage can be located by means of residual force vector, structural stiffness matrix in undamaged state must be known in advance. 殘余力向量能夠識(shí)別結(jié)構(gòu)損傷位置，但需要預(yù)先獲得結(jié)構(gòu)完好狀態(tài)下的剛度矩陣；
A new two-step damage identification method based on residual force vector considering the impact of measurement error(noise) in most cases is proposed. 提出了一個(gè)考慮模態(tài)噪聲影響的基于殘余力向量法的損傷識(shí)別兩步法。
