- Abstract:
- In order to study the shear lag effect of large span composite box girder bridge with corrugated steel webs, a large span composite box girder bridge with corrugated steel webs using cantilever construction was adopted, and the plane frame model and finite element model were established respectively. The construction processes were simulated and three key sections were selected. The distribution rules of shear lag effect of large span composite box girder bridge with corrugated steel webs at different stages of construction were studied. The results show that the shear lag effect of large span box girder bridge with corrugated steel webs is a dynamic process with the construction stage. The shear lag effect changes rapidly during cantilever construction stage, and changes slowly at the late stage of construction. The maximum shear lag effect occurs on the end section at the maximum cantilever state.
