Development of Fragility Curve Database for Multi-Hazard Performance Based Design
… responses of structures subjected to hazard; 2) fragility curves; 3) consequence functions. Fragility curves were critically analyzed to determine the source and the process of development of the curves, but structural analysis results and consequence functions were not critically analyzed due to …

Computational Modeling of Glass Curtain Wall Systems to Support Fragility Curve Development
… analytical results obtained were used to support fragility curve development which could aid in multi-hazard PBE design of CWs. A 3D finite element (FE) model of a single panel CW unit was generated including explicit modeling of the CW components and component interactions such as …

Assessment of the Seismic Vulnerability of Wall Pier Supported Highway Bridges on Priority Emergency Routes in Southern Illinois
… 100 dynamic time-history analyses (required for fragility curve construction). Details concerning the analytical sub-models used for representing the various bridge components in these models are given, as is information concerning the structural limit states that were considered in the analyses. …

Behaviour and modelling of the inelastic response of concrete and steel-concrete infrastructures subjected to low-cycle fatigue
… a refined F.E. model in ABAQUS was developed. Fragility curve parameters of the damage's interest quantities were obtained by fitting experimental and numerical data by means of the Maximum Likelihood Estimation method. The results and the numerical model could be ready for the application of …

Seismic Response and Analytical Fragility Functions for Curved Concrete Box-Girder Bridges
Curved bridges are constructed to conform to geometric constraints resulting from traffic and structural restrictions. They are different from their straight counterparts since the response coupling in the longitudinal and transverse directions and rotation of the superstructure may lead to …

Impact of complex system behavior on seismic assessment of RC bridges
… risk posed to bridges with irregular or curved geometry subjected to multi-directional loading is non-trivial. The effect of the resulting combined interactions on structural response and its implications on system-level bridge vulnerability are assessed in this study. Fragility curves …

Integrated Microgrid Expansion Planning and Policy Making under Uncertainty in Power Electricity Market
An interconnected microgrid is a group of Distributed Energy Resources (DER) with the ability to operate in a grid connected mode. DERs include nondispatchable renewable generation such as wind and solar units as well as small scale dispatchable resources such as diesel generators, microturbines, …

Approcci innovativi per la sicurezza delle infrastrutture strategiche: valutazione speditiva della vulnerabilità sismica di ponti con machine learning e analisi sperimentale avanzata su conci per gallerie
… con elevata accuratezza i parametri chiave delle curve di fragilità (capacità mediana μ e dispersione β) a partire da un set limitato di dati geometrici e meccanici facilmente reperibili. I risultati dimostrano che tale approccio supera i limiti computazionali dei metodi convenzionali e i limiti …

Development and application of new system reliability analysis methods for complex infrastructure systems
The failure event of a structure or lifeline network is often described by a complex logical function of multiple component failure events. Despite significant advances in theories on reliability analysis of individual components and their adoption in practice, the critical knowledge and …
