This paper reviews the technical research concerning health monitoring of civil structures under varying temperature conditions, covering the correlation between measuring responses and temperature, the influence of temperature on responses, separation and forecast methods of temperature-induced part of responses data, and proposed process frameworks of damage assessment considering temperature effects.
Suffering from solar radiation, day-night replacement and seasonal changes, the structure will produce notable temperature behaviour, which has a vital effect on the long-term process of the health monitoring. Previous studies show that there is a significant correlation between the measuring responses and temperature from health monitoring systems. To analyse the structural state more accurately, much literature employed health monitoring methods considering temperature effects. This paper reviews technical research concerning health monitoring of civil structures under varying temperature. Firstly, the correlation researches of structural measuring responses (dynamic and static responses) and temperature are reviewed, which includes the researches of the influence mechanism and the data statistics, and the studies of the influence of non-uniform temperature on responses are also reviewed. In addition, different types of separation and forecast methods of the temperature-induced part of the structural responses data are summarized, followed by a brief summary of benefits and drawbacks of these methods. Lastly, the recently proposed process frameworks of damage assessment considering temperature effects are also introduced.
