A new numerical-based fragility relation for cast iron (CI) pipelines with lead-caulked joints
subjected to seismic body-wave propagation is proposed in this article. Two-dimensional …

The socio-economic and environmental impact, in case of severe damage on Natural Gas
(NG) pipeline networks, highlights the importance of a rational assessment of the structural …

Pipelines as infrastructure components are very vulnerable to geohazard-induced
phenomena such as ground deformation, slopes failure and others. Understanding the …

Abstracts Corrosion, ageing, and other failure factors pose safety hazards to underground
natural gas pipelines. In actual rescue operations, in addition to paying attention to leakage …

Ground motion intensity measure (IM), which is a key link between the seismic hazard
analysis and structural seismic response analysis, plays an important role in the …

As an important part of a city's “lifeline,” an urban underground natural gas pipeline network
is an integral part of the infrastructure, facilitating energy transmission. If the source of a leak …

Soil structure interaction (SSI) may affect significantly the seismic vulnerability of structures
with several mechanisms that depend on the mutual effects of soil properties and structural …

Earthquakes may cause severe damage to the technological infrastructure and to transport
systems handling hazardous substances as oil, natural gas and flammable/toxic chemicals …

Transport infrastructure, such as tunnels and underground structures, are usually built using
reinforced concrete solutions. Since the 1970s, many transport structures (culverts, bridges …

This paper investigates the optimal intensity measure (IM) for underground structure in
probabilistic seismic demand models. A two-dimensional finite element model that accounts …
