Study on Bend Performence of Binding Bars Prestressed Steel Box Concrete Beam

Abstract:

Put forward binding bars prestressed concrete filled steel box girder and analyses it’s advantage, Study on the bending moment by the fiber model method to analyze the beam-Curvature and load-Relation curves of deflection theory.Through the finite element software analysis of prestressed concrete steel box beam prestressed concrete filled steel tubes and four ways to set binding bars the ultimate bearing capacity of the beam,Analysis of the influence of the thickness of the steel plate and rod diameter, constraint, constraint rod axial spacing on various beam flexural capacity.The results show that,Binding bar has more advantages for prestressed concrete steel box using a thin plate bending ability improvement,Diameter, spacing of the binding bars binding bars as long as not bending capacity of prestressed concrete with binding bars of steel box beam structure under the condition of impact.
