Research on the Bottom Support Reaction Force of the Special-shaped Block Beam of the Special-shaped Steel Box Girder
Taking a special-shaped steel box girder bridge in a municipal overpass reconstruction project as an example,this paper studies the relationship between the support reaction force of the special-shaped end and the section form of the transverse beam at the support.Firstly,it provides an overview of the project and the special-shaped steel box girder it adopts.Secondly,Midas Civil software is used for finite element modeling,and the support reaction force is calculated.It is found that the support reaction force of the special-shaped end is greatly affected by the section form of the transverse beam,and when the transverse beam adopts the box section,the distribution of the support reaction force is significantly different from that of other section forms.Therefore,the relationship between the support reaction force and the transverse beam section is further studied,and the box section is finally determined as the optimal section form for transverse beam modeling.
