Abstract

Abstract

In order to study the influence of corrosion on the flexural property of H-shaped steel beams, the standard tensile specimens and steel beams were cut off from H-shaped steel members corroded in the atmospheric environment for three years. The monotonic tensile test of corroded steel and bending test of corroded steel beams were conducted. The relations of yield strength, ultimate strength and ductility with section loss ratios of corroded H-shaped steel beams was discussed, and the change low of the yield load and ultimate load of corroded H-shape steel beams with loss rate of strong axis moment of inertia was revealed. The calculation method of flexural capacity of corroded steel beams was proposed. The results showed that with the increase of corrosion degree, the yield strength, ultimate strength, yield strength and ultimate strength of corroded H-shaped steel beams decreased gradually.
