This paper studies ionospheric vertical total electron content (VTEC) variations before the 2014 Mw8.2 Chile earthquake. VTEC derived from 14 GPS (Global Positioning System) stations and GIM (Global Ionospheric Map) were used to analyze ionospheric variations before the earthquake using the sliding interquartile range method, and results showed that significant positive VTEC anomalies occurred ...

Damage of the urban gas network due to an earthquake can cause much loss including fire-induced loss to infrastructure and loss due to interruption of gas service and repairing or replacing of network elements. In this paper, a new fire ignition model is proposed and applied to a conventional semi-probabilistic model for estimating various losses due to damage of an urban gas network in an eart...

An experimental investigation is performed to assess the characteristics of the fluid– structure interactions and microburst-induced wind loads acting on a wind turbine model sited in microburst-liked winds. The experiment study was conducted with a scaled wind turbine model placed in microburst-like winds generated by using an impinging-jet-typed microburst simulator. In addition to quantifyin...

Many mechanical and structural systems respond dynamically to random environmental loads, such as wind, wave or earthquake forces. Examples include flexible buildings vibrating due to turbulent wind loading and offshore structures moving as a result of combining wave and wind loading. To assess the reliability of such structures it is important to predict their dynamic response, at the design s...

On a jack-up structure acts static loads (own weight, machines, installations and materials weight) and dynamic loads (waves, wind, marine currents, earthquake, operating installations). The authors led their analysis on the determining the dynamic loads produced by waves, wind and marine currents, in the Black Sea, because these are the main source in collapse of the structure. The structural ...

We study the dynamic response of a wind turbine structure subjected to theoretical seismic motions, taking into account the rotational component of ground shaking. Models are generated for a shallow moderate crustal earthquake in the Madrid Region (Spain). Synthetic translational and rotational time histories are computed using the Discrete Wavenumber Method, assuming a point source and a horiz...

ABSTRACT: Shear wall is commonly employed as a principal element to resist lateral loads due to wind or earthquake forces. An accurate model for a shear wall system needs to consider the effect of all components for analyses i.e. shear wall, foundation, and subsoil. This investigation presents the modeling of a shear wall structure foundation and soil system using the super element, finite and ...
