“…Space structures are rather sensitive to temperature variations because of their high degrees of static indeterminacy [16][17][18]. Therefore, it is necessary for structural design and construction calculations to study the practical temperature distributions and variations in space structures.…”

Due to the dynamic coupling effects of solar radiation, longwave radiation, convective heat transfer, shadows, and other factors, the temperature field and effect of steel structures are significantly non-uniform, differing from traditional concepts that regard the temperature variation of steel structures as a slow and uniform progress. This difference can hinder the correct understanding of the thermal behavior of steel structures and ignore some potential safety hazards. This paper provides a review of the studies for the non-uniform temperature field and effect of steel structures, and presents some outlooks on future developments on the basis of the current research situation. A summary of research on the temperature field and effect of space structures, bridges and radio telescopes initially establishes the basic cognitive framework for this field. In addition, then, the basic principles of the numerical simulation of temperature fields are introduced through heat transfer mechanism, and the experimental test methods of temperature and its effects are described based on typical test cases. Finally, with a view to the future, some suggestions and opinions are provided in consideration of deficiencies in the current research status. This paper hopes to provide some valuable references for future research in this field through research summary, method introduction and outlook.

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 20 o C 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.

“…Therefore, the thermal load is usually the control load for large-span steel structures and there has been growing attention to the structural behavior of steel structures under thermal change. Alinia and Kashizadeh conducted some work on the structural behavior of spherical double layer space truss domes under uniform thermal load [1][2][3]. However, for the steel structures exposed to solar radiation, its temperature is much larger and more non-uniformly distributed than the corresponding ambient air temperature in summer.…”

ABSTRACT:The temperature change of large-span steel arch structures normally appears when the structures are exposed to solar radiation, which may result in large displacement and stress. Therefore, there has been growing attention to both temperature distribution and structural response of the structures under the solar radiation. In order to investigate the response of large-span box-sectional steel arch structures formed by rectangular steel tubes, one rectangular steel tube specimen was designed and its temperature was measured under solar radiation. A numerical method was presented according to transient thermal analysis and then verified by experimental results. Both experimental and numerical results showed that the solar radiation had a significant effect on the temperature distribution of rectangular steel tubes. Considering the solar radiation, the temperature of rectangular steel tubes is about 18.1 o C higher than the corresponding ambient air temperature in summer. Moreover, the temperature distribution under solar radiation is extremely nonlinear. In order to study the structural response induced by the temperature change due to the solar radiation, a steel arch structure model is designed and the structural response due to temperature change is also investigated on this model. The results showed that the solar radiation has a remarkable effect on the thermal load response of large-span steel structures. The effect of the solar radiation has to be considered in the design process of large-span steel arch structures.
