Seismic Fragility Analysis of Structural Systems

Journal of Engineering Mechanics, 2006
A method is presented for the evaluation of the seismic fragility function of realistic structural systems. The method is based on a preliminary, limited, simulation involving nonlinear dynamic analyses performed to establish the probabilistic characterization of the demands on the structure, followed by the solution of a general system reliability ...

SEISMIC FRAGILITY ASSESSMENT OF MEDICAL COMPONENTS

Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015
Shake table tests on a full scale three-dimensional model of a consultation room has been carried out at the University of Naples, Federico II ,Italy . The sample room con-tains a number of typical medical components, which are either directly connected to the panel boards of the perimeter walls or are simple free-standing elements.

Bridge fragilities to network fragilities in seismic scenarios: An integrated approach

Engineering Structures, 2021
Abstract As significant uncertainties are associated with the factors governing the operational characteristics of bridges following earthquakes, it is important to compute the reliability of transportation networks as a function of bridge fragility. A novel framework for the computation of transportation network fragilities following earthquakes is ...

On the importance of uncertain factors in seismic fragility assessment

Reliability Engineering & System Safety, 2013
Abstract This paper addresses the definition of importance measures for helping the modeller to detect the factors on which to focus modelling activity and data collection in seismic fragility analysis. We study sensitivity measures consistent with the decision-support criteria of interest, namely, the (mean) fragility curve and the “High Confidence ...

Seismic performance by fragility surfaces

2014
A method is developed for constructing fragilities as functions of two parameters, source-to-site distance, r, and moment magnitude, m. The method is based on a seismological model for site ground motion and seismic activity matrices available from USGS.

Seismic fragility of traction elevators

Earthquake Engineering & Structural Dynamics, 2015
SummarySecond‐generation performance‐based earthquake engineering (PBEE‐2) requires a library of component fragility functions to estimate probabilistic damage to a wide variety of building components. The present work draws on a large body of (mostly) post‐earthquake reconnaissance and (some) post‐earthquake survey observations of traction elevators ...

Seismic Fragility Methodology for Highway Bridges

Structures Congress 2006, 2006
Bridge fragility curves, which express the probability of a br idge reaching a certain damage state for a given ground motion parameter, play an important role in the overall seismic risk assessment of a transportation network. For various reasons, analytical methodologies for developing these fragility curves have experienced an increase in demand and

Seismic Fragility of Suspended Ceiling Systems

Earthquake Spectra, 2007
Full‐scale dynamic testing of suspended ceiling systems was performed to obtain fragility data suitable for performance‐based assessment and design. On the basis of the fragility data derived from testing, (1) the use of retainer clips improves the performance of ceiling systems in terms of loss of tiles, (2) including recycled cross tees in the ...

Seismic Fragility of a Highway Bridge in Quebec

Journal of Bridge Engineering, 2013
The seismic vulnerability of the Chemin des Dalles Bridge over Highway 55 located in Trois-Rivieres (Quebec, Canada) was evaluated through fragility analysis using field- and laboratory-validated models. This approach offers an effective means to capture the uncertainties in ground-motion realizations, the demands placed on key structural components ...

Fragility Functions for Seismic Risk in Regions with Moderate Seismicity

2011
The seismic assessment of existing buildings has been underestimated in regions with moderate seismic hazard, such as the North-West Europe. Strong earthquakes, such as the 1356 Basel earthquake, already occurred in such regions and caused severe damage.
