Corrosion Effect on Truss Bridge - Compression Chord Reliability

/up/images/featured/images/044.png

Abstract: This paper presents several aspects of the method for reliability assessment of compression chords of railway bridges considering non-linear general corrosion damage. A method is proposed to determine the probability density function of the ultimate strength using a response-surface approach coupled with FEM. It includes a stochastic finite element structural model and probabilistic models for corrosion propagation. A parametric study of various corrosion models is employed to examine how the buckling resistance will vary in time. The limit state is given in analytical form using the response-surface approximation.

Keywords: compression chords, corrosion models, response surface, compression chord resistance
