This paper presents the temperature variation of steel structures with different colors subjected to solar radiation by means of experiments. Steel plate specimens of standard size with different colors wereexposed to sunlight to measuretemperaturechangesover the courseof aday in various places. Then, a one-dimensional heat conduction model is established to simulate the output surface temperature of steel plate specimens by using the environmental parameters obtained from experiment, and the numerical results are compared with the experimental results to prove its feasibility. On the basis of this model, the influence of different factors on the temperature change of steel structures is studied.
