TLDR
SelEQ, a fully integrated framework that implements state-of-the art procedures for ground motion record selection and scaling, makes use of the Adaptive Harmony Search meta-heuristic optimization algorithm in order to significantly minimize computational cost and analysis time, whilst still meeting the imposed selection constraints.About:

An open-source framework for regional earthquake loss estimation using the city-scale nonlinear time history analysis
TL;DR: In this article, a nonlinear time history analysis of buildings is used to simulate the seismic damage of buildings in the event of an earthquake, and the simulation provides decision-makers with important information for earthquake disaster prevention and mitigation.
Journal ArticleDOI
Selection of earthquake ground motions for multiple objectives using genetic algorithms
TL;DR: Application of the proposed framework for the optimum selection of earthquake GMs shows that it is able to track GM sets that not only provide excellent spectral matching but they are also able to simultaneously consider more explicitly a set of additional criteria.
Journal ArticleDOI
Failure analysis of a Portuguese cultural heritage masterpiece: Bonet building in Sintra
TL;DR: The seismic vulnerability assessment of the Bonet building is carried out following two different approaches, enacted in two distinct numerical models: the so-called Equivalent Frame Method (EFM) and the Finite Element Method developed in 3Muri and ABAQUS software, respectively.
Journal ArticleDOI
A more rational selection of the behaviour factor for seismic design according to Eurocode 8
TL;DR: The fragility and seismic risk assessment conducted shows that all building archetypes, regardless of the q-scenario considered, exhibit values of mean annual frequency of collapse that comply with limits available in the literature.
Journal ArticleDOI
OpenSeismoMatlab: A new open-source software for strong ground motion data processing.
TL;DR: The structure, algorithms and main routines of the program are explained in detail and the results for various types of spectra of 11 earthquake strong ground motions are calculated and compared to corresponding results from other proprietary software.

A New Heuristic Optimization Algorithm: Harmony Search
TL;DR: A new heuristic algorithm, mimicking the improvisation of music players, has been developed and named Harmony Search (HS), which is illustrated with a traveling salesman problem (TSP), a specific academic optimization problem, and a least-cost pipe network design problem.

Conditional Mean Spectrum: Tool for Ground-Motion Selection
TL;DR: In this paper, the authors proposed the use of the conditional mean spectrum (CMS) as the appropriate target response spectrum for ground motion selection in dynamic structural analysis, which is a useful tool for selecting ground motions as input to dynamic analysis.
Journal ArticleDOI
Earthquakes, Records, and Nonlinear Responses
TL;DR: In this article, the estimation of MDOF nonlinear structural response given an earthquake of magnitude M at distance R is studied with respect to issues such as the benefits and harms of first scaling the records, selecting records from the “wrong” magnitude, and alternative choices for how to scale the records.

Earthquake Ground-Motion Prediction Equations for Eastern North America
Gail M. Atkinson,David M. Boore +1 more
TL;DR: In this article, a stochastic finite-fault model was used to predict ground motion for hard-rock and soil sites in eastern North America (ENA), including estimates of their aleatory uncertainty (vari- ability).
