Description
Technical Field
The invention relates to the technical field of bridge engineering, in particular to a buckling restrained structure of a large-span corrugated steel web box girder and a construction method.
Background
In recent years, the corrugated steel web combined box girder bridge is rapidly developed and widely applied to various practical projects. Compared with a common concrete box girder, the wave-shaped steel web box girder reduces the dead weight by about 20%, meanwhile, the wave-shaped steel web box girder has the advantages of high prestress efficiency and the like, the wave-shaped steel web girder bridge can exceed the concrete web girder bridge to reach larger span, the limit span reaches 400m, the maximum span of the built wave-shaped steel web girder bridge is 160m, and the span is far less than the maximum span of the built concrete web girder bridge, and is less than the limit span of the wave-shaped steel web combined box girder bridge.
As the bridge span increases, the box Liang Gaodu increases accordingly, and the buckling stability problem of the corrugated steel web becomes particularly prominent, which becomes one of the main factors restricting the increase of the bridge span of the corrugated steel web. Taking 1600-type corrugated steel web with the thickness of 30mm as an example, when the height h of the corrugated steel web exceeds 6.9m (the span of the beam bridge is estimated to be 178m according to the high span ratio), the integral buckling critical stress is positioned in the inelastic domain of steel, the buckling stress is smaller than the yield stress, and the integral buckling critical stress is greatly reduced along with the continuous increase of the height of the web, so that the material cannot be fully exerted.
Currently, in order to improve the overall buckling stability of the corrugated steel web, the main method is to increase the thickness of the corrugated steel web or to arrange a concrete lining on the inner side of the steel web to form a combined web. The thickness of the steel plate is increased, the effect of improving the overall buckling stability of the corrugated steel web is not obvious, the material is uneconomical to use, and meanwhile, the processing and mounting difficulties are increased. The inner side of the steel web is provided with lining concrete, so that the shearing stress of the corrugated steel web can be reduced, the stability of the corrugated steel web is effectively improved, but the lining concrete is arranged to limit the wrinkling effect of the corrugated steel web, reduce the prestress application efficiency of the corrugated steel web composite bridge, increase the dead weight of the bridge and prevent the span of the corrugated steel web composite bridge.
