Spatial Effects and Broken-up Analysis for Bottom Plates of Box Girders in a Large Span Rigid Frame - Continuous Beam Bridge

Abstract:

The author took a rigid frame-continuous beam bridge for example, analyzed by means of plane finite element and space finite element methods. In the space model, corrugated pipes were built in order to consider the weaken effects to cross-sections. Aimed at the least well stage which is after prestressing and before grouting, spatial stresses were indicated. Final results indicate exceeded transverse tensile stresses caused by radial forces are the most important factor which led to bursting cracks.
