Study of modern seismic zoning maps' accuracy (case for Eastern Uzbekistan)

Geodesy and Geodynamics, 2016
Influence of uncertainty factors of input parameters on results of the estimation of seismic hazard has been researched. It is found that the largest deviations, from seismic hazard maps designed on the basis of average values of distribution of seismic ...

Regional Adjustments to NGA‐West2 Ground‐Motion Models for Turkey

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a ground‐motion model updating (GMMU) framework to adjust NGA‐West2 models for predicting a set of intensity measures in Turkey, including peak ground acceleration (PGA), peak ground velocity (PGV), and pseudo‐spectral acceleration (PSA) at periods ranging from 0.01 to 10 s. The GMMU framework integrates bias identification

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

A Probabilistic Seismic Hazard Analysis Method Incorporating Physics-Based Simulation and Ground Motion Prediction Equation

International Journal of Disaster Risk Science
The traditional approach to probabilistic seismic hazard analysis (PSHA) relies on ground motion records, which restricts its application in regions with sparse seismic records or low seismicity.

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Integrating faults and past earthquakes into a probabilistic seismic hazard model for peninsular Italy

, 2017
Italy is one of the most seismically active countries in Europe. Moderate to strong earthquakes, with magnitudes of up to ∼ 7, have been historically recorded for many active faults. Currently, probabilistic seismic hazard assessments in Italy are mainly

Designing Web-enabled services to provide damage estimation maps caused by natural hazards [PDF]

, 2010
The availability of building stock inventory data and demographic information is an important requirement for risk assessment studies when attempting to predict and estimate losses due to natural hazards such as earthquakes, storms, floods or tsunamis ...

Covariance Structure Modeling of Engineering Demand Parameters in Cloud‐Based Seismic Analysis

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Probabilistic seismic demand modeling aims to estimate structural demand as a function of ground motion intensity—a critical stage in seismic risk assessment. Although many models exist to describe the structural demand, few consider the covariance among engineering demand parameters, potentially overlooking a key factor in improving the ...

Seismic Fragility Analysis of Containment Structures in Nuclear Power Plants Considering Alkali‐Silica Reaction

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study quantifies the influence of alkali‐silica reaction (ASR) on the seismic fragility of prestressed concrete containment structures in nuclear power plants (NPPs). Global collapse was considered as the governing failure mode to maintain consistency with current risk assessment frameworks, and was captured using a finite element model ...
