According to theoretic analysis, computing the bending deflection of every roller is enabled to ignore the effect of the web and only allow to the rectangular section made up of flange plates.

Taking the reinforced concrete and prestressed concrete works in one expressway as example from two aspects: camber and lower flexibility setting of simple beam the differences between the lower flexibility of reinforced concrete simple beam and the camber deformation of presstressed concrete simple beam are presented.

Design of structural parameters and bending deflection of straightening machine for conducting bar

It is difficult to get a proper practical answer of bending deflection for H-Beam roller straightening.

In order to avoid flaws in the process of H-beam straightening, an adequate mechanical model was established and the relations between bending moments, forces and bending deflections of the H-beam in nine-roller straightening were deduced.
