Experimental Study on Force Bearing of Long Span Wide Steel Box Girder Cable-Stayed Bridge in Construction Stage
In the design and construction of long-span steel box girder cable-stayed bridges,shear lag is often an important factor affecting the stress of bridge structures.A certain waterway super large bridge is a wide-section steel box girder cable-stayed bridge,which adopts cantilever assembly construction to study the influence law of the current section and the current section working condition on the shear lag effect of the completed beam section tested.The results show that The stress is constantly changing as the construction phase changes.On the whole,the stresses at different positions of each section are increasing.From 11:00 to 15:00,the stresses at each measuring point of the beam increase,including the compressive stress at the top of the beam and the tensile stress at the bottom of the beam.
