Abstract

Abstract

In order to study the mechanical properties of continuous curved composite girder bridges during operation, taking the actual project of ramp C of Zhibu South Junction as the background, considering the influence of the connection mode of the diaphragms and the curve radius, three continuous curved composite girders with a scale reduction ratio of 1∶10 compared with the actual case were designed. Static load tests under four operating conditions were carried out.The load-deflection curves and the distribution law of the control sections strain along the height and transverse direction under the working conditions were obtained. A comparative study found that under the four operating conditions the partial load of the outer box was the most disadvantaged for cross-center deflection. The eccentric load factor of the composite girder was around 1.30. The curve radius had a certain effect on the mechanical properties of the curved composite girder, and the connection method of the diaphragms had little effect on it.
- steel-concrete continuous curved composite girders,
- bending-torsion performance,
