“…The darker the surface coating, the higher the temperature of the steel plate, and the maximum temperature difference between steel plates with different surface coatings was up to 19.3 • C in summer. Chen also studied the temperature effects of steel members under rigid and hinged constraints induced by solar radiation through on-site monitoring and numerical analysis [25]. The thermal deformation of all specimens, which included I-shaped steel, a rectangular tube, and a circular tube, was relatively small and less than 1/3000 of their spans.…”

“…Based on comparative analysis of the test data, it was shown that the time-variance laws of girder temperature and girder deflection were similar, and there was a basically linear relationship between the temperature field and the deflection of the box girder at night, indicating that the girder deflection was greatly affected by the girder temperature. This method of determining the layout of measuring points to measure temperature effect was also applied in the studies of Chen [25], Zhao [27], Wang [45], etc.…”

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.

“…Similarly, Zhao et al [3] stated that components connected to supports were sensitive to thermal loads and the internal force can be released by deformation. Chen et al [4] investigated the effect of temperature changes on steel members in a suspen dome and concluded it is significant and should not be overlooked. Researchers have addressed the thermal effect on suspended and inclined cables [5][6][7].…”

Realizing that an important factor such as thermal load must be considered during analysis and design for a cable system, this paper presents the behavior of elastic cable based on differential thermal theorem namely catenary-based approach. To this end, the traditional known materialsteel-and carbon fibre reinforced polymer were subjected to varying temperature values through simulation and the behaviour pattern were compared. Results obtained showed that the influence of temperature on steel cable is more evident with higher values than carbon fibre reinforced polymer. This makes carbon fibre reinforced polymer cable an ideal substitute when it comes to application in regions with high temperature.

“…Besides, several researchers [27,28] did experiments on different shapes of steel members under solar radiation considering shadow effect, providing resources for thermal design. However, those studies have focused on relatively small concrete bridges [22,23], composite bridges [24], steel shell [25], steel box girders [26][27][28], and steel members of I or H shape [29,30], which have a relatively limited value of reference on the thermal studies of steel truss aqueducts.…”

Aqueduct, one kind of bridge structure overpassing a long space, is a significant structure for water delivery for the purpose of agricultural or domestic usage. Aqueduct has quite different loads from other forms of bridges, of which temperature effects due to the environment temperature change, such as seasonal weather or radiation from sunshine, are of great importance. With water flowing inside, the temperature boundary of aqueducts, especially for steel aqueducts, is much more complicated, and relevant researches are limited. In this paper, a 3D Finite Element Method (FEM) simulation process is presented to analyze temperature distribution on the cross-section of a new-type steel truss aqueduct, which belongs to the Water Transfer Project from Yangtze River to Huai River in China. ASHRAE clear-sky model is used to calculate the solar-radiation variation, including direct radiation, diffuse sky radiation, and ground reflected radiation on steel surfaces. The time-dependent sunshine radiation angle of incidence and shielding effect of steel trusses are considered. The water inside the aqueduct is also included in this model, which significantly influences the temperatures of the inner surfaces of the aqueduct. Several temperature distributions under critical conditions of winter and summer are shown in this study, and results of the empty aqueduct under the same circumstances are also provided as a comparison. The effects of wind speed, geographic latitude, and direction of the aqueduct are examined. The conclusions and approach provided by this study could serve as significant references for thermal design and control of similar steel truss aqueducts.
