The present paper aims to quantify the relation between structural temperatures and its natural frequencies via thermodynamic approach. A simply-supported beam was tested in laboratory. The temperature values at different points were recorded continuously in one day, together with a series of forced modal testing to extract its frequencies. A thermodynamic model is established to estimate the temperature distribution of the slab and compared with the measurement data. The frequencies of the slab are calculated, and the variation of frequency with respect to temperature is established and verified by the experiment. The present study provides a new approach to investigate the environmental effect on structural responses.
