Study on Spatial Effect of Wide Box Girders under Unbalance Loading

Abstract:

Prestressed concrete continuous wide box girder bridge is widely used in urban bridges, because of its large width-span ratio, spatial effects from unbalance load cannot be ignored. When the bridge was analyzed by beam element system, the increased coefficient of unbalance loading is used to simplified space problem into plane problem. Spatial effect of wide box girder under unbalance loading is calculated by solid finite element method, and used in a project example in Hangzhou. Comparing analysis results of solid finite element with other simplified methods, it shows that the solid element method is more applicable and accurate. This method and results offer reference for similar bridge design calculation.
