A review of prognostics and health management in wind turbine components
(2024-06-27)
Article
Open AccessWind turbines (WTs) play an essential role in renewable energy generation, and ensuring their reliable operation is essential for sustainable energy production and reduction of levelized cost of energy. In this context, ... -
Probabilistic estimation of the dynamic response of high-rise buildings via transfer functions
(Elsevier, 2024-03)
Article
Open AccessThe significant number of seismic ground motion records to be considered when designing or assessing civil structures is a common restriction for employing advanced nonlinear dynamic methods. This is because the large ... -
Comparison of earthquake risk for masonry and RC buildings in Barcelona using existing sets of vulnerability functions
(Springer, 2023-10-20)
Article
Open AccessBarcelona is in an area of low- to medium-seismicity and its earthquake vulnerability and risk has been assessed in different studies over the last 20 years. Most of these works have developed vulnerability models for the ... -
Seismic pushover analysis of unbraced adjustable pallet racks in the down-aisle direction. Need for multimode analysis
(2023-12)
Article
Restricted access - publisher's policyModal Pushover Analysis has been proposed to account for the higher modes contribution in seismic analysis of slender structures, such as unbraced racks in the down-aisle direction. In these structures, only single-mode ... -
Customary light-gauge steel framing construction with flat strap bracing. Seismicity limits for short to mid-rise buildings in Europe
(Springer, 2023-11-20)
Article
Open AccessOrdinary (customary) light gauge steel framing is a convenient construction technology; however, given the studs low axial capacity, it has been considered mainly for low-rise buildings in low seismicity regions. This paper ... -
Low lateral stiffness underground structures for improved seismic performance: application to the Kobe Daikai station
(Elsevier, 2023-09)
Article
Open AccessUnderground cut-and-cover structures are commonly designed as rigid box sections; however, in practical applications, connections between walls and slabs are frequently rather hinged (because of ease of construction). The ... -
Estimators for structural damage detection using principal component analysis
(2022-09)
Article
Open AccessStructural damage detection is an important issue in conservation. In this research, principal component analysis (PCA) has been applied to the temporal variation of modal frequencies obtained from a dynamic test of a ... -
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, ...
