Improving Post-Earthquake Building Safety Evaluation using the 2015 Gorkha, Nepal, Earthquake Rapid Visual Damage Assessment Data

Earthquake Spectra, 2017
A Rapid Visual Damage Assessment was initiated in the direct aftermath of the 2015 Gorkha earthquake to assess the safety and damage of residential buildings in the areas affected by the earthquake. Over 30,000 paper assessment forms have been subsequently digitized.

Automated vision-based post-earthquake safety assessment for bridges using STF-PointRend and EfficientNetB0

Structural Health Monitoring, 2023
Bridges are critical transportation infrastructure in Taiwan that are at high risk of structural damage during major earthquake incidents. The structural health monitoring method currently used to assess bridge safety nationwide is labor-intensive and expensive to implement.

Running Safety Assessment of Trains on Bridges under Earthquakes Based on Spectral Intensity Theory

International Journal of Structural Stability and Dynamics, 2021
The main goal of this paper is to perform the safety assessment of high-speed trains (HSTs) on the simply supported bridges (SSBs) under low-level earthquakes, which are frequently encountered by HSTs, utilizing spectral intensity (SI) index. First, the HST’s limit displacements, which are calculated by using the multi-body train model with detailed ...

Dynamical Seismic Probabilistic Safety Assessment for Earthquake

2012
In the nuclear power plants (NPPs), the earthquake could make a critical result because of its catastrophe risk. It is important to maintain the stability of the system without the radiation material leak from the reactor. The system dynamics (SD) is used in analysis by the random sampling quantification of the earthquake happening due to unexpected ...

Nature of probability in safety assessments and application to earthquakes

Nuclear Engineering and Design, 1980
Abstract The protection of nuclear installations against earthquakes requires as a first step a realistic description of seismic ground motions which are likely to occur, with their corresponding probabilities. However, large discrepancies in probability evaluations appear between the opinions of the experts for a given site. This paper addresses the

Running safety assessment of trains moving over bridges subjected to moderate earthquakes

Earthquake Engineering & Structural Dynamics, 2015
SummaryA study about the running safety of trains moving over bridges subjected to earthquakes is presented. The study focuses on moderate earthquakes with relatively small return periods and high probability of occurrence. The analyses are performed using a nonlinear train‐bridge interaction method proposed by the authors, being the running safety ...

Earthquake Risk Assessment for Seismic Safety and Sustainability

2018
An interaction of three major risk components (seismic hazards, vulnerability and exposure) are analysed here, and preventive measures to mitigate disasters are discussed. The importance of action-oriented research on earthquake risk reduction co-produced with multiple stakeholders, including engineers and policymakers, is analysed.
