| Abstract: | It was analyzed that the space effect of a prestressed stee l-concrete curved beam bridge with a small radius according to the pr inciple of prestressed space equiv alent load,and combining actual pr ojects.The influence of prestresse d space effect of the composite be am on the torque of the main beam and support reaction was also anal yzed.Some effective measures,such as the support eccentricity and ba llast etc were taken during its de sign process.The bending effect wa s also taken into account in the a seismic design and that of the sup port bracket. |
