Seismic Fragility Functions for Sewerage Pipelines

Pipelines 2015, 2015
Fragility functions (or fragility curves when presented graphically) are a well established tool to assess seismic risk to infrastructures. Given a sustained level of ground motion intensity, seismic fragility functions of sewerage pipelines are used for predicting earthquake-induced physical damage to sewer pipes. However, existing fragility functions

Fragility of seismically isolated FBR structure

Nuclear Engineering and Design, 1991
The purpose of this study is to present a methodology for the estimation of the fragility of an isolated FBR (Fast Breeder Reactor) structure. The method is based on the regression analyses between the intensity and response of an earthquake motion.

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.

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

Fragility functions for seismic risk in regions with moderate seismicity

2010
Current seismic risk evaluations are mostly based on approximate vulnerability curves. Damage prediction is improved by considering structural characteristics of building. Such improved fragility functions do not exist for many structures, especially in countries with moderate seismicity.

SEISMIC FRAGILITY ANALYSIS OF FRAME STRUCTURES

International Journal of Structural Stability and Dynamics, 2008
A seismic fragility analysis of structures is essential to prediction of the building behavior that is likely to occur during earthquakes. Normally, the probability of failure of a structure over a specified period of time is obtained through a convolution of the fragility curve with the seismic hazard curve for the structure site.

On the computation of seismic fragility curves

2008
Seismic damage assessment is dealt with in terms of fragility curves. Several approaches for their evaluation, including first-order reliability and a fuzzy random method, are reviewed. These methods are applied to a deterministic infilled reinforced-concrete frame, and the resulting fragility curves compared.
