在钢结构应力监测过程中，温度对应力监测结果影响明显，为了得到钢结构真实的载荷应力，采用小波多分辨分析方法对实时测量数据进行分解和重构，首先对信号进行去噪，然后利用温度数据与各分解层下应力数据的相关关系，剔除出温度应力部分，研究结果表明，采用小波多分辨分析方法处理后的应力数据更能准确的反映钢结构真实的载荷应力响应。
在鋼結構應力鑑測過程中，溫度對應力鑑測結果影響明顯，為瞭得到鋼結構真實的載荷應力，採用小波多分辨分析方法對實時測量數據進行分解和重構，首先對信號進行去譟，然後利用溫度數據與各分解層下應力數據的相關關繫，剔除齣溫度應力部分，研究結果錶明，採用小波多分辨分析方法處理後的應力數據更能準確的反映鋼結構真實的載荷應力響應。

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.
