Modelling and Integration of Spatial Time-Dependent Variability in Structural Reliability Analysis

点击翻译按钮获取中文摘要

This project deals with some theoretical aspects of the increasingly important practical problem of realistic assessment of the remaining safe and serviceable life of deteriorating infrastructure. It uses cutting-edge techniques in stochastic structural mechanics to model spatial variability due to pitting corrosion in reinforced concrete structures. This is then extended to the time dependent domain to reflect deterioration processes. These are calibrated to experimental data generated in the project. In parallel, a novel technique is developed to incorporate these spatial models in procedures for time dependent structural reliability analysis. The outcomes will enhance engineering risk assessment for infrastructure decision-making.
