The El Niño-Southern Oscillation (ENSO) is an ocean-atmosphere phenomenon involving sustained sea surface temperature fluctuations in the Pacific Ocean, causing disruptions in the behavior of the ocean and atmosphere. We develop a Markov switching autoregressive model to describe the Southern Oscillation Index (SOI), a variable that explains ENSO,...

Over time, considerable changes in the earth's climate have always occurred due to a wide variety of natural processes. During the last century, these natural changes have all been accelerated by global warming, which has been driven by human activities. Climate change leads to wide variations in the environmental variables such as temperature, rel...

Chloride ingress into concrete is the primary cause of steel corrosion that leads to the deterioration of reinforced concrete (RC) assets and eventual reduction of its service life. The maintenance of RC buildings and structures has become a major concern, and thus the development of an effective maintenance plan is required. This study focuses on...
Article
Full-text available
Onshore pipelines are usually subjected to a corrosion attack. Regular inspections known as In-Line inspections (ILI) are commonly used with magnetic (MFL) or ultrasonic (UT) tools to prevent any failure. New defects will appear between consecutive inspections due to the aggressiveness of the surroundings and the detection thresholds associated wit...

Tools exist to predict fatalities related to floods, but current models do not focus on fatalities in buildings. For example, Storm Xynthia in France in 2010 resulted in 41 drowning deaths inside buildings. Therefore, there has been increasing recognition of the risk of people becoming trapped in buildings during floods. To identify buildings which...
Article
Full-text available
The attack of chloride ions is one of the most important factors affecting reinforced concrete (RC) durability. Chloride ingress into concrete is usually studied by assuming constant diffusivity and constant surface chloride concentration. However, these two approximations could badly estimate the chloride concentration in RC structures and then th...

Corrosion and natural events are some of the more significant threats for onshore pipelines because of their frequency and potential severity. Corrosion defects reduce the wall thickness and can lead to a burst due to the internal pressure. Extreme events after seismic activity, either by transient (TGD) or permanent ground deformations (PGD), can...

Underground pipelines have a space-dependent condition that arises from various soil properties surrounding the pipeline (e.g., moisture content, pH, aeration) and the efficiency of protection measures. Corrosion is one of the main threats for pipelines and is commonly monitored with in-line inspections (ILI) every 2 to 6 years. Preliminary charact...

Large structures are systems composed by a significant number of components with parallel or series distributions. How these components fail and interact, aggravate the complexity of the main structure reliability calculation. Some methods commonly proposed to reduce this complexity by dividing the system into segments of similar properties using d...

Corrosion defects affect the structural integrity of onshore pipelines making them prone to a Loss of Containment (LOC). LOCs may trigger significant consequences over the surrounding people and environment. Therefore, In-Line (ILI) inspections are commonly implemented to measure indicators of the metal loss along the pipe due to corrosion to suppo...
