Attention-based deep recurrent neural network to forecast the temperature behavior of an electric arc furnace side-wall
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-12)
Article
Open AccessStructural health monitoring (SHM) in an electric arc furnace is performed in several ways. It depends on the kind of element or variable to monitor. For instance, the lining of these furnaces is made of refractory materials ... -
Novel seismic design solution for underground structures. Case study of a 2-story 3-bay subway station
(Elsevier, 2022-02)
Article
Open AccessThis paper proposes an innovative seismic design approach for shallow rectangular cut-and-cover underground subway or railway stations. The traditional approach is to design rigid frame-like structures by connecting rigidly ... -
Data classification methodology for electronic noses using uniform manifold approximation and projection and extreme learning machine
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-12-22)
Article
Open AccessThe classification and use of robust methodologies in sensor array applications of electronic noses (ENs) remain an open problem. Among the several steps used in the developed methodologies, data preprocessing improves the ... -
Manifold learning algorithms applied to structural damage classification
(2021-06-05)
Article
Open AccessA comparative study of four manifold learning algorithms was carried out to perform the dimensionality reduction process within a proposed methodology for damage classification in structural health monitoring (SHM). Isomap, ... -
Structural damage classification in a jacket-type wind-turbine foundation using principal component analysis and extreme gradient boosting
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-04-13)
Article
Open AccessDamage classification is an important topic in the development of structural health monitoring systems. When applied to wind-turbine foundations, it provides information about the state of the structure, helps in maintenance, ... -
A simplified approach to account for directionality effects on 2D dynamic soil-structure interaction analysis
(CRC Press, 2019)
Conference report
Restricted access - publisher's policyIn this study, a simplified approach to account for directionality effects on twodimensional (2D) dynamic soil-structure interaction analyses (DSSI) is proposed. When an earthquake is recorded, the direction with the maximum ... -
Acquisition and processing of buildings’ vibrations using a Real-Aperture Radar, a non-invasive method
(2018)
Conference report
Restricted access - publisher's policyIn this paper, a simplified non-invasive method to diagnose the safety state of buildings is tested. The method is based in remote sensing measurements of the natural vibrations of actual buildings using an interferometric ... -
New capacity and energy based damage index
(2018)
Conference report
Open AccessNon-linear dynamic analysis and the damage index of Park-Ang have been often used to assess expected seismic damage to a structure. Depending on the size of the structure and the duration of the record, the computational ... -
Comparison among design solutions for precast buildings in medium-to-moderate seismicity zones
(World Conference on Earthquake Engineering, 2021)
Conference report
Restricted access - publisher's policyThis paper compares, mainly in terms of construction cost and rapidity, two seismic-resisting systems for low-to-midrise precast buildings in moderate-to-medium seismicity zones (in Spain): (i) ordinary buildings accounting ... -
Case study of a heavily damaged building during the 2016 MW 7.8 Ecuador earthquake: directionality effects in seismic actions and damage assessment
(2021-02)
Article
Open AccessIn this work, the directionality effects during the MW 7.8 earthquake, which occurred in Muisne (Ecuador) on 16 April 2016, were analyzed under two perspectives. The first one deals with the influence of these effects on ... -
Entropy indicators: an approach for low-speed bearing diagnosis
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-02-01)
Article
Open AccessTo increase the competitiveness of wind energy, the maintenance costs of offshore floating and fixed wind turbines need to be reduced. One strategy is the enhancement of the condition monitoring techniques for pitch bearings, ... -
A strong-motion database of Costa Rica: 20 Yr of digital records
(2020-11)
Article
Open AccessIn this article, we present a strong-motion database from earthquakes recorded by the Earthquake Engineering Laboratory at the University of Costa Rica. The database consists of 2471 three-component accelerograms from 155 ...
