Changes of modal frequencies induced by temperature variation can be more obvious than those caused by structural damage, which will lead to the false damage identification results.
Therefore, quantifying the temperature effect on modal frequencies is a critical step to eliminate its interference in damage detection.
Due to the nonuniform and time-dependent characteristics of temperature distribution, it is insufficient to obtain the reliable relationships between temperatures and modal frequencies using temperatures in air or at surface.
In this paper, correlations between measured temperatures (air temperature, surface temperature, mean temperature, etc.) and modal frequencies for the slab and beam are comparatively analyzed.
And the quantitative models are constructed considering nonuniform temperature distribution.
Firstly, the reinforced concrete slab and beam were constructed and placed outside the laboratory to be monitored.
Secondly, the correlation coefficients between modal frequencies and three kinds of temperatures are calculated, respectively.
Thirdly, simple linear regression models between mean temperature and modal frequencies are established for the slab and beam.
Finally, five temperature variables are selected to construct the multiple linear regression models.
Prediction results reveal that the proposed multiple linear regression models possess favorable accuracy to quantify the temperature effect on modal frequencies considering nonuniform temperature distribution.
