A new parametric study based on the Proper General ized Decomposition for the evaluation of the seismic vulnerability of buried pipelines
Pipelines related to industrial supplies such as oil or gas are a key p art of modern development, so it is important to ensure their appropriate response to a seismic action. The same applies to drainage or water supply in contemporary cities. Structural analysis of pipelines is a well-estab lished topic in engineering practice. In this paper, we…
Adapting oil & gas infrastructures to climate change
It is well known that natural disasters which are related to climate change (e.g. rising sea levels, heat stress, extreme precipitation, inland and coastal flooding, landslides, water scarcity etc.) are rapidly increasing through last decades.
