- Abstract
In order to fully understand the shear lag effect variation of concrete composite girder with steel truss webs, the 3D finite element model is established with general finite element software ANSYS, considering three typical load models of mid-span concentrated load, two points symmetrical load and uniform load. The effect of geometric parameters on shear lag effect of simply supported concrete composite girder with steel truss webs is analyzed. Geometric parameters include the span-width ratio, the width-height ratio and wing-thickness ratio. The results show that under three load cases, the influence of the span-width ratio and the width-height ratio on shear lag effect of the prestressed concrete composite girder with steel truss webs was analyzed. The results show that the span-width ratio has greater influence on shear lag effect of the prestressed concrete composite girder with steel truss webs, while the width-height ratio and other parameters have less influence on shear lag effect. And the results indicate that for continuously supported prestressed concrete composite girder with steel truss webs, the negative shear lag effect is quite obvious near the cross-section of mid-support, which needs to attach great importance in the design.
