The study of large-scale complex structure damage diagnosis had become more and more important. Discussed a kind of effective method for damaged diagnosis base on the improving Cross Modal Strain Energy (CMSE) technique and the Modal Strain Energy Rate (MSER). Through improvement of the existing modal strain energy indexes, discussed using only low-order modes for the bridge structure damage diagnostic...
The main purpose of this study is to introduce bridge working conditions assessment method. This problem had become more and more important in the bridge operation process. The bridge system reliability analysis method in this study was based on the results of bridge components reliability. Bridge system reliability assessment index selected Markov process steady-state probabilities. In order to study...
