In the steel structure stress monitoring process, the temperature plays a significant role on stress monitoring results.In order to get the real load stress of steel structure, the real-time measurement data were decomposed and reconstructed by using the wavelet multi-resolution analysis method.Firstly, it eliminated the noise signal.Then, it analyzed correlation between the temperature data and the stress data in each decomposition level.Finally, the temperature-stress part.Was removed were removed the results showed that the processed stress data by using the wavelet multi-resolution analysis can reflect the true load stress response of steel structure more accurately.
