Experimental Study on the Overall Stability of Corroded H-Shaped Steel Beams

The degradation of the overall stability corroded rolled H-shaped steel beams under bending conditions has not been extensively studied. In present study, monotonic tensile tests and were conducted on seven that subjected to electrochemical corrosion in order discuss influence material’s mechanical properties conditions. test results have indicated strength, elastic modulus, elongation declined with an increase rate beams, obvious plastic deterioration phenomenon was observed. addition, all different degrees flexural–torsional buckling failure. stiffness ultimate bearing capacity decreased rate, a high design degraded significantly. Furthermore, by using finite element numerical simulation analysis software ABAQUS, double-reduction model sectional dimensions established. capacities three-point corresponding load–lateral displacement curves analyzed. compared for verification. Subsequently, initial analyzed virtue verified model. This study will provide basis evaluation existing members, as well experimental reference follow-up members.
