Abstract
In this paper the results of a study aimed at evaluating the strength of wideflanged beams subjected to corrosioninduced damage modeled using a standard finite element program ABAQUS is presented and discussed Typical beams in consideration were subjected to different cases of corrosioninduced damage such as nonuniform and varying degree of material loss that simulates pitting corrosion Many variables such as a shape of pitting damage b location of pits along the length of the beam c number of pits and d depth of pits were considered to facilitate a better understanding of the load carrying capacity of steel Ibeams having damage quite similar to pitting damage to the web The results are compared with an “asnew” beam for purpose of evaluation of the reduction in strength due to environmentinduced deterioration A “corrosion strength reduction factor CSRF” is introduced to help identify the reduction in load carrying capacity as a consequence of both height and depth of the damage due to corrosion The results are presented in charts for purpose of practical beam designThe authors extend most sincere thanks and abundance of appreciation to the unknown reviewers for their useful comments which has helped strengthen the revised manuscript This work is associated with the National Center for Education and Research on Corrosion and Materials Performance NCERCAMP at The University of Akron and the DoD Technical Corrosion Collaboration supported by the US Department of Defense Office of Corrosion Policy and Oversight administered by CERL
