Summary The increasing number of wind turbines in active tectonic regions has attracted scientific interest to evaluate the seismic vulnerability offshore (OWTs). This study aims at assessing deformation and collapse susceptibility 2MW 5MW OWTs subjected shallow‐crustal pulse‐like ground motions, which not been particularly addressed date. A cloud‐based fragility assessment is performed quantify response for a given intensity measure assess failure probabilities non‐pulse‐like motions....
In recent years steel-concrete composite shear walls have been widely used in enormous high-rise buildings. Due to high strength and ductility, enhanced stiffness, stable cycle characteristics large energy absorption, such can be adopted the auxiliary building; surrounding reactor containment structure of nuclear power plants resist lateral forces induced by heavy winds severe earthquakes. This paper demonstrates a set nonlinear numerical studies on I-shaped subjected reverse cyclic loading....
The probabilistic seismic performance of a standard Korean nuclear power plant (NPP) with an idealized isolation is investigated in the present work. A hazard analysis (PSHA) Wolsong site on peninsula performed by considering peak ground acceleration (PGA) as earthquake intensity measure. procedure reported categorization and selection two sets motions Tohoku earthquake, i.e. long-period common Set B respectively, for nonlinear time history response base-isolated NPP. Limit state values...
Due to the severe impacts of recent earthquakes, use seismic isolation is paramount for safety nuclear structures. The diversity observed in events demands ongoing research analyze devastating attributes involved, and hence enhance sustainability base-isolated power plants. This study reports performance a seismically-isolated reactor containment building (NRCB) under strong short-period ground motions (SPGMs) long-period (LPGMs). United States Nuclear Regulatory Commission-based design...
Abstract A base material of Al 80 -Ni 20 was used and mixed with variable proportions Nano chromium oxide (Cr 2 O 3 ) at percentages 2, 4, 6, 8 10%, as well magnesium (MgO) 10%. These mixtures were then applied using the thermal spraying method a flame. This particular is commonly for repairing cracks protecting turbine blades in electric power stations from external corrosion. However, it important to note that this may face challenges when exposed high-temperature water vapour, salts other...
Wind turbines are dynamically complex structures. They entail slender towers, flexible foundations, and heavy rotor-nacelle-assembly (RNA). In the context of earthquake analysis, RNA is often simplified as a rigid point mass which can suppress modal contribution blades from global system dynamics may further affect reliability seismic response wind turbines. Other high-fidelity finite element (FE) blade models difficult to implement due layup composite materials reduced computational...
