[I-354] The consideration which is a prestress loss in long span PC slab with cross beam
Keywords:Long span PC slab, Cross beam, Prestress loss, FEM analysis
In a steel girder bridge with wide and ramp alignment, In order to cope with width changes, a structure in which the number of main girders is changed in the cross beam section is generally used.
It is considered that restraint by cross beam affects prestress loss of PC slab.
There is also concern about the impact of pre-stressing on the separation of floor slabs in consideration of future removal. We perform FEM analysis and report the result of examining pre-stress loss considering restraint by cross beam and construction step.
