Corrosion of steel by concrete
TL;DR: In this paper, the authors examined the reactions of various concretes on steel reinforcement and concluded that the most significant influences on the corrosion of prestressing wire in concrete are: the presence of chloride, presence of nitrates, the composition of concrete, the degree of carbonation of the concrete; concrete compaction and chlorides and sulphates should be used as far as possible when steel is embedded.

Assessment of lifetime seismic resilience of a long-span cable-stayed bridge exposed to structural corrosion
TL;DR: In this paper , the authors proposed a probabilistic methodology for evaluating the lifetime seismic resilience of a cable-stayed bridge considering the effect of structural corrosion, including the corrosion of steel bars, reduction of concrete strength, and corrosion of high-strength stay cables, and the nonlinear static analysis was conducted to directly relate the reduced seismic capacities with the predefined damage states to facilitate seismic fragility analysis.

Incremental dynamic analysis
TL;DR: Incremental dynamic analysis (IDA) is a parametric analysis method that has recently emerged in several different forms to estimate more thoroughly structural performance under seismic loads as mentioned in this paper, which involves subjecting a structural model to one or more ground motion record(s), each scaled to multiple levels of intensity, thus producing one (or more) curve(s) of response parameterized versus intensity level.
