Silva, J.E., Garbatov, Y. e Guedes Soares, C. (2013), “Ultimate strength assessment of rectangular steel plates subjected to a random non-uniform corrosion degradation”, Engineering Structures, Vol. 52, pp. 295-305
The objective of the present study is to investigate the effects of corrosion shape surface on the ultimate strength of unstiffened rectangular steel plates subjected to uniaxial compressive load. Two new and distinct corrosion surface models are proposed and investigated. A total of 3575 corroded plate surface geometries are generated by Monte Carlo simulation for different degrees of degradation, location and ages and nonlinear finite element analyses are carried out, using a commercial finite element code. Based on a regression analysis, empirical formulae to predict strength reduction due to corrosion have been derived demonstrating a good accuracy.
