Abstract

Abstract

In order to study the influence of corrosion damage on the bearing capacity of H-shaped steel members under compression, especially the local buckling performance, six short H-shaped steel short columns with different degrees of corrosion were designed. Firstly, the outdoor accelerated corrosion test for up to 15 months was carried out, then the monotonic tensile test of plates and the eccentric compression test of short columns were carried out, finally the relationship between corrosion degree and mechanical property parameters, such as failure mode, ultimate bearing capacity, and deformation property, was analyzed. The results showed that with the increase of corrosion degree, the ultimate load and critical buckling load of H-shaped steel columns decreased gradually; corrosion led to the decrease of the half wavelength of local buckling, which weakened the plastic deformation capacity of the specimen and reduced the bearing capacity of the member under eccentric compression.
