Abstract

Abstract

Taking Haihuang Bridge in Qinghai Province as engineering background, a finite element analytical model of composite girder temperature field was established under consideringmeteorological parameters and verified by the field test data of bridge. The vertical temperature distributions of上-shaped composite girder in all seasons were analyzed, and the simplified patterns of vertical temperature gradient during warming and cooling were proposed. The influence rules of meteorological parameters such as solar radiation intensity, temperature and wind velocity on the temperature difference were studied. Based on the extreme statistic method, the worst vertical temperature gradient patterns of上-shaped composite girders with different asphalt concrete laying thicknesses under the meteorological parameter represent values in 50-year return period were calculated. Analysis result shows that during warming in day and cooling at night, the vertical temperature gradient patterns of composite girder are different. The maximum temperature difference during warming takes place at 14:00, and the temperature gradient pattern can be simplified as the linetype with 5-parabola at the top and broken line at the bottom. The temperature difference at the top is greatly influenced by the laying thickness of asphalt concrete. When the laying thicknesses are 0, 50, 100, 150 mm, respectively, the maximum temperature differences at the top are 23.8 ℃, 31.7 ℃, 24.1 ℃ and 17.4 ℃, respectively. The maximum temperature difference at the bottom is 5.1 ℃. The minimum temperature difference during cooling takes place at 2:00, and the temperature gradient pattern can be simplified as the linetype with double broken line at the top and isothermal section at the bottom. The temperature difference at the top is greatly influenced by the laying thickness of asphalt concrete. When the laying thicknesses are 0, 50, 100, 150 mm, respectively, the minimum temperature differences at the top are -12.2 ℃, -8.2 ℃, -5.0 ℃ and -2.9 ℃, respectively. The minimum temperature difference at the bottom is -16.4 ℃. Because the vertical temperature distribution of 上-shaped composite girder is influenced by the meteorological parameters, the temperature nearly keeps linear relationship with daily solar radiation amount and air temperature, and keeps nonlinear relationship with wind velocity. The proposed vertical temperature gradient pattern of 上-shaped composite girder during warming is close to the pattern in AASHTO, but the temperature difference at the top is 1.7 ℃ higher than the value in AASHTO. The temperature gradient pattern during cooling is close to the pattern in Eurocode, but the temperature difference at the bottom is 8.4℃lower than the value in Eurocode. Therefore, the proposed temperature gradient patterns are more critical.
