Analysis of random backscattering in ground-penetrating radar signals to detect subterranean watercourses - Field results and laboratory tests
(2019)
Conference report
Restricted access - publisher's policyThe studies of seismic risk in Barcelona city required nanozonation because measurements of soil response in the plain of Barcelona present sudden changes in small areas, highlighting the importance of a most detailed study ... -
On the equal displacement aproximation for mid-rise reinforced concrete buildings
(Institute of Structural Analysis and Antiseismic Research School of Civil Engineering. National Technical University of Athens (NTUA), 2019)
Conference report
Open AccessThe equal displacement approximation is a well-known procedure for estimating the non-linear behavior of structures subjected to earthquake ground motions. This procedure plays a significant role in current seismic design, ... -
Remote ambient vibration measurements with real aperture radar to estimate buildings dynamic properties
(Institute of Structural Analysis and Antiseismic Research School of Civil Engineering. National Technical University of Athens (NTUA), 2019)
Conference report
Open AccessThe use of sensors to obtain the dynamic properties of structures by means of ambient vibrations has become a common practice. However, conventional and more extensively used methods require the installation of sensors, ... -
Laboratory tests in rigid pavement
(2019)
Conference report
Open AccessDeterioration of concrete structure is consequence of aging, applied loads and weathering. In this paper, several laboratory tests were presented, compared to computational models and a field test case study. The purpose ... -
Study of structural elements in heritage buildings with ground penetrating radar images
Conference lecture
Open AccessMaintenance and repairing or ancient buildings requires efforts and a wide knowledge of the structures. However, in many cases, the constructive methods, the distribution of supporting elements and the materials are unknown. ... -
Damage detection using principal component analysis applied to temporal variation of natural frequencies
(2018)
Conference report
Restricted access - publisher's policyFor preserving existing structures to the extent possible, vibration-based damage detection techniques are gaining more attention. In specific, tracking the changes in a structure’s natural frequencies employing the Principal ... -
Analysis and calibration of Ground Penetrating Radar shielded antennas
(2018)
Conference report
Open AccessGround-Penetrating Radar (GPR) is a non-destructive geophysical method applied in many civil engineering applications. The knowledge of the GPR antennas behavior is crucial to obtain accurate results and comprehensive data ... -
GPR building inspection: Examples of building structures assessed with Ground Penetrating Radar
(University of Edinburgh, 2017)
Conference report
Restricted access - publisher's policyThe GPR assessment of buildings depends on the structure or part of the building studied. In this paper, three different case study are presented, all of them about old buildings that need to be restored or modified. ... -
Seismic damage assessment of URM buildings: a comparison of non-linear static procedures
(2016)
Conference report
Restricted access - publisher's policyIn the scientific literature, a significant number of non-linear procedures are proposed in order to evaluate the seismic vulnerability of a building. In this work, and in the context of the Risk-UE methodology, a complete ... -
Capacity curve based damage index for steel buildings: a probabilistic approach
(2016)
Conference report
Restricted access - publisher's policyThe capacity and expected seismic damage of several types of steel buildings are assessed by using a probabilistic approach. Nonlinear static and dynamic analyses are performed by means of Monte Carlo Simulations. Concerning ... -
Evaluation of seismic damage in low-rise buildings of reinforced concrete masonry
(2016)
Conference report
Restricted access - publisher's policyThe assessment of damage caused by earthquakes in structures, requires the use of nonlinear analysis, either static or dynamic, in order to define the performance of the buildings for the considered hazard levels. In this ... -
New parametric model for capacity curves and a new capacity based damage index
(2016)
Conference report
Restricted access - publisher's policyA recently proposed parametric model re-conceptualizes capacity curves as composed by linear and non-linear parts. The normalized non-linear capacity curve can be modelled by a cumulative lognormal function. While the ...
