Model Tests Study on the Bending Properties of the External Pre-Stressed Combination Box Girders with Corrugated Steel Webs

Abstract:

In order to study actual work performance of the external pre-stressed combination box girder with corrugated steel webs, and to analyse the integral stress of box girder influenced by the corrugated steel webs, and understand the construction of the type combination box girder, this document studied the model test of the external pre-stressed combination box girder with corrugated steel webs, tried to find out the bending rule for the combination box girder and the model test result influenced by the different connections style. And the model test result was based on the assumption of “flat section” and within the elastic range, when the concentrated loads loaded on the box girder, the deflection was linear with the loads, and the corrugated slab stress was zero, which indicated the slab can not bended and the moment was supported by the top and the bottom slab, and the corrugated slab only supported the shear, and the shear lag effect only influenced local area. The conclusion of the model test will provide the reference for the bending capacity research, design and construction.
