Bayesian damage characterization based on probabilistic model of scattering coefficients and hybrid wave finite element model scheme
(2019)Ultrasonic Guided Wave(GW) has been proven to be sensitive to small damage. Motivated by the fact that the quantitative relationship between wave scattering and damage intensity can be described by scattering properties, ... -
Experimental investigation of jet pulse control on flexible vibrating structures
(2016)The feasibility of applying on-line fluid jet pulses to actively control the vibrations of flexible structures subjected to harmonic and earthquake-like base excitations provided by a shake table is explored. The operating ... -
Failure analysis of a welded steel pipe at Kullar fault crossing
(2017)The seismic response of a 2200-mm-diameter welded steel pipe at strike slip Kullar fault crossing in Izmit, Kocaeli during 1999 Kocaeli earthquake is investigated. The pipe was crossing the fault-line with an angle of 55° ... -
Permanent earthquake-induced actions in buried pipelines: Numerical modeling and experimental verification
(2018)Buried pipelines are often constructed in seismic and other geohazard areas, where severe ground deformations may induce severe strains in the pipeline. Calculation of those strains is essential for assessing pipeline ... -
Railway-induced ground vibrations in the presence of local track irregularities and wheel flats
(2015)Rapid growth in railway infrastructure has led to numerous environmental technical challenges. This includes ground-borne vibration, which is becoming an increasing problem, particularly in urban environments. A common ... -
Rotational capacity of pre-damaged I-section steel beams at elevated temperatures
(2017)Structures submitted to Fire-After-Earthquake loading situations, are first experiencing inelastic deformations due to the seismic action and are then submitted to the thermal loading. This means that in the case of steel ... -
A statistical study of precursor activity in earthquake-induced landslides
(2017)In this paper, a statistical study of precursor activity in earthquake-induced landslides by means of spring block models is presented. The dynamic behavior of the rock/soil slope can be studied by using the statistics of ...
