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, ... -

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 ... -
Dynamic monitoring of a mid-rise building by real-aperture radar interferometer: advantages and limitations
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-03)
Article
Open AccessIn this paper, remote and in situ techniques to estimate the dynamic response of a building to ambient vibration are reported: data acquired through a real-aperture radar (RAR) interferometer and conventional accelerometers ... -
Increased seismic hazard in Barcelona (Spain) due to soil-building resonance effects
(Elsevier, 2019-02)
Article
Open AccessIn this study, previous microzonation studies in Barcelona (Spain) were revisited, and available data on the predominant periods of soils in the city were compiled to develop an updated microzonation map of the city. In ... -
An efficient method for considering the directionality effect of earthquakes on structures
(2021-09)
Article
Open AccessRecent research have proven the importance of considering the directionality effect on the expected seismic damage of structures. However, it demands a high computational effort if the nonlinear dynamic analysis (NLDA) is ... -
Assessment of post-earthquake damaged building with interferometric real aperture radar
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-12-01)
Article
Open AccessIn this study the main results of a detailed analysis of an actual building, which was severely damaged during the Mw 5.1, May 11th 2011, Lorca earthquake (Murcia, Spain) are presented. The dynamic behavior of the building ... -
A drift-correlated ground motion intensity measure: application to steel frame buildings
(Elsevier, 2020-05)
Article
Open AccessEstimations of seismic risk in urban areas should include quantifications of the expected damage to civil structures subjected to earthquakes. In buildings, this quantification depends on the maximum inter-story drift ... -
Dynamic soil-structure interaction analyses considering directionality effects
(Elsevier, 2020-03)
Article
Restricted access - publisher's policyThe paper investigates directionality effects of ground motions in the context of dynamic soil-structure interaction (DSSI) analyses. The problem addressed corresponds to a nonlinear soil deposit, overlaying firm ground, ... -
Lab non destructive test to analyze the effect of corrosion on ground penetrating radar scans
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-12-01)
Article
Open AccessCorrosion is a significant damage in many reinforced concrete structures, mainly in coastal areas. The oxidation of embedded iron or steel elements degrades rebar, producing a porous layer not adhered to the metallic ... -
