Concrete-filled steel tubes (CFSTs) have been applied widely as the main members in bridge structures; however, the temperature gradients have not been studied sufficiently. To fill this gap, a long-term experimental and analytic study was conducted on four CFST members with different inclinations and orientations. Then a systematic 2-step approach with curve fitting and extreme value analysis (EVA) was proposed to establish the most unfavorable vertical temperature gradient (VTG) and transverse temperature gradient (TTG) patterns with the extreme temperature differences (TDs) in a 100-year return period. The curve fittings show that both VTG and TTG profiles can be described by two piecewise functions with multiple parabolas. And EVA shows that TDs in positive VTG, negative VTG, and positive TTG all fit the Weibull distribution well, while the TDs in negative TTG all fit the Gumbel distribution better. Comparison analysis shows that the Chinese specification underestimates the temperature gradients of CFST bridges. The proposed temperature gradient patterns are more suitable for probabilistic limit-state design for thermal effect calculations of CFST bridges than the Chinese specification.

The water temperature at 100-300 m depth layer impact on bigeye tuna distribution has been studied from data collected by 15 fishery survey vessels, surveying every day, in the Equatorial Pacific Ocean from February to March and June to September 2010. The in situ ocean temperature measurements at four depths (100, 150, 200, and 300 m), satellite data and TAO/TRITON moored buoy data were also augmented in this study. The results reveal stereoscopic temperature factors for the prediction of tuna fishing ground: horizontal temperature gradient (HTG), vertical temperature gradient (VTG) in the 100-300 m layer. Maximal catches were observed where (1) vertically there has a strong subsurface temperature front in the 150-200 m layer, with horizontal temperature gradient up to near 0.020 degrees C/km; (2) there have vertical temperature gradient between -0.088 and -0.066 degrees C/m. Meanwhile, the monthly tuna fishery catches decrease with the synchronized reduction of 20 degrees C isotherm depth in the ocean. (C) 2020 COSPAR. Published by Elsevier Ltd. All rights reserved.
