Numerical Analysis of Shear Lag Effect for Concrete Huge Section Box Grider

Abstract:

Article Preview

Through a lot of investigations and studies ,and refering to the current related technical specifications and relevant reference, and combining with the characteristics of the ordinary concrete box section component , single box double room concrete huge section box girder which can realize city bridges double traffic is devised creatively,considering of the need of structure and function. By choosing proper element type and material modle, the designed box grider is modeled by the nonlinear analysis software ANSYS. The shear lag effect of the concrete huge section box girder is studied by applying four load conditions including prestressed load, the upper and lower live load and double load. Parameter analysis are done, which include the load type and width-span ratio.And corresponding conclusions are drawn.
