Probabilistic structural reliability assessment of underground shaft steelwork

Highlights Novel, fully probabilistic structural reliability analysis of shaft steelwork. Guiding forces and corrosion loss inspection data input the reliability assessment. Considers design and operation factors hitherto omitted by steelwork design codes. Variant analysis of guiding forces, corrosion loss, dynamic interactions and limit states.
Abstract Industrial and government regulations on underground shaft steelwork operations require high maintenance standards; however, the design procedures are highly simplified, significant risk sources are not considered, and adequate reliability assessments are not involved. In this study, we deployed maintenance measurements of the guiding forces and corrosion loss for actual load effects and resistance representations in terms of probability distributions. This allowed the statistical generalization and fully probabilistic reliability analysis of the shaft guide track. The probability of failure was assessed through the numerical integration of the convolution integral. Parametric analysis was performed for different guiding forces, corrosion loss, dynamic load characteristics, and limit states. The proposed procedures enable a fully probabilistic structural reliability assessment of shaft steelworks with respect to the design and operation factors that have been omitted so far. Therefore, the proposed methodology provides a modern tool for design and maintenance optimization during the shaft steelwork lifecycle.
