Abstract
This paper presents a method for predicting the nominal compressive strength of steel I-shaped piles subject to cross-sectional losses caused by corrosion. The method requires a finite element linear buckling analysis of the corroded cross-section. Results from the finite element buckling analysis may be integrated into design capacity equations contained in the 15th edition of the American Institute of Steel Construction Steel Construction Manual. Non-linear post-buckling analyses were used to verify the accuracy of the proposed method. Three cross-sectional geometries (W14x82, W14x90, and W14x120) were analyzed at varying degrees of cross-sectional loss. Results show close agreement between the non-linear finite element analyses and the proposed method of calculating nominal compressive strength.
Highlights
This paper presents a method (the Fe(buckle) method) for predicting the nominal compressive strength of steel Ishaped piles subject to cross-sectional losses caused by corrosion
Linear and non-linear final element studies of three I-shaped cross-sections were reconciled with design capacities using the 15th edition of the American Institute of Steel Construction Steel Construction Manual (AISC manual) [1]
Preliminary conclusions from the results presented in this work indicate that non-linear post-buckling analyses conducted in ABAQUS are in close agreement with AISC equation models for the noncorroded cross-sections
Summary
The goal of the study was to form a predictive model that could be used to determine residual capacity in a corroded compression member
