Abstract
A full-scale, three-storey, light timber frame of a residential house was tested in-situ to investigate the effect of structural damage, temperature and relative humidity changes on its natural frequency. As expected, test results provide the evidence of the significant influence that temperature and relative humidity changes have on the natural frequency of the test structure. Regression analysis of the test results revealed that the natural frequency change of the structure is generally in a linear relationship with the variation of both relative humidity and temperature. Furthermore, variation of natural frequency induced by relative humidity and temperature may be much stronger than that induced by damage of structural members. It is concluded and recommended that the effect of temperature and relative humidity change should be considered when the natural frequency is used as an indicator for damage identification of timber constructions.
