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 ...

Comparative seismic fragility assessment of mid-rise steel buildings with non-buckling (BRB and SMA) braced frames and self-centering energy-absorbing dual rocking core system

Soil Dynamics and Earthquake Engineering, 2021
A bstract During the past two decades, many emerging smart lateral force-resisting systems have been proposed for achieving better post-earthquake recoverability than the conventional ones in steel buildings.

Fuzzy seismic fragility analysis of gravity dams considering spatial variability of material parameters

, 2021
Due to the heterogeneity of massive concrete and unevenness of pouring process, concrete strengths in gravity dams show obvious spatial variability. In addition, since the evolution of damage states for gravity dams is a gradually transitional process ...

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 and damage assessment of reinforced concrete bridge pier under long-duration, near-fault, and far-field ground motions

, 2021
Observations from recent earthquakes around the world have revealed the destructive nature of near-fault ground motions that cause significant damage to structures. On the other hand, the effect of long-duration motions on seismic demands has attracted a

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.

Pilot Large Diameter Pipeline Seismic Fragility Assessment

Pipelines 2012, 2012
The East Bay Municipal Utility District (EBMUD) is a major water utility providing water to over 1.3 million people on the eastern side of the San Francisco Bay Area. EBMUD has approximately 4,200 miles of treated water distribution and transmission pipelines within a 331-square-mile customer service area.

Probabilistic seismic fragility and loss analysis of concrete bridge piers with superelastic shape memory alloy-steel coupled reinforcing bars

, 2020
Concrete bridge piers with conventional steel reinforcing bars are vulnerable to strong earthquakes by inducing significant residual deformations, which substantially weakens the seismic resilience of bridges.

Seismic fragility assessment of concrete gravity dams

Earthquake Engineering & Structural Dynamics, 2003
AbstractMany concrete gravity dams have been in service for over 50 years, and over this period important advances in the methodologies for evaluation of natural phenomena hazards have caused the design‐basis events for these dams to be revised upwards.
