Abstract: The temperature change is very large for steel structures under solar radiation, and this temperature change can induce remarkable nodal displacement and member stress. In order to obtain the temperature distribution and thermal behavior of large span steel structures under solar radiation, a numerical simulation method was presented in this paper based on the ASHRAE model. In order to provide insights into temperature distribution and provide data to verify the presented numerical simulation method, ten steel plate specimens with different aspect ratios and orientations were investigated by measuring their temperatures under solar radiation. The parameter values in the numerical simulation model were modified by the tests results. Using the temperature numerical simulation method, the temperature distribution and thermal behavior of a typical steel structure, the lattice shell structures, were studied. The study showed that: 1) the solar radiation had a significant effect on the temperature distribution of steel structures. Considering the solar radiation, the temperature of steel structures is about 20oC higher than the corresponding ambient air temperature; 2) the temperature change is similar to sine curve from sunrise to sunset; 4) the solar radiation has a remarkable effect on the member stress, nodal displacement and reaction force.
