摘要: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。
Abstract: 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.
