Negative moments of two-span continuous RC slab bridges with various skew angles and span lengths are studied through the time history analysis for moving vehicle. Responses of bridges are evaluated by FEM time history method used in the previous study, which was verified by comparing the measured data. The velocity of moving vehicle is selected as 60 km/h, since the variation of the vehicle velocity does not show noticeable effect upon the response displacements. From the result of negative moments for various values of the skew angels, the maximum moments occur at the skew angle around . It can be said that the bridge with middle range of skew angles show the biggest load effect compared to those with small angle or straight bridges( skew angle). It is also found that the rate of increment of negative moment also increases as the span length increases. The better design for skewed bridges could be possible as response analysis for the more various loading conditions and bridge types would be conducted in the future. |
