Abstract

This paper presents residual stress distributions in roller bent wide flange HE 100B sections obtained from experiments. The wide flange steel beams are curved at ambient temperature by means of the roller bending process, which alters the initial residual stress pattern. Curved wide flange steel sections are frequently used in large span structures like roofings and bridges. Their geometry and loading often make these arches susceptible to instability phenomena’s. An accurate knowledge of the residual stresses is therefore necessary. An experimental program was set up to investigate the residual stresses in roller bent sections. Measurements were carried out on straight and curved sections. It was found that the residual stresses in roller bent sections differ significantly from those in their straight counterparts.
