Application of Spatially Correlated and Coherent Records of Scenario Event to Estimate Seismic Loss of a Portfolio of Buildings
T. J. Liu,Han Ping Hong +1 more
TL;DR: In this article, the authors extend the stochastic finite-fault model to simulate spatially correlated and coherent records for a scenario seismic event and estimate the seismic loss of spatially distribute spatially distributed records.

Large scale random fields generation using localized Karhunen–Loève expansion
TL;DR: The generation of random fields when the domain is much larger than the characteristic correlation length is made using an adaptation of the Karhunen–Loève expansion (KLE) to guarantee the continuity of the field and a proper representation of the covariance function on the whole domain.

Half-tapering strategy for conditional simulation with large datasets
Denis Marcotte,Denis Allard +1 more
TL;DR: In this article, the authors proposed to use the taper covariance only in the conditioning step (half-taper or HT approach), which enables to speed up the computations and to reduce memory requirements for the condition step but also to keep the right short scale variations in the realizations.

Reliability analysis of active tendon‐controlled wind turbines by a computationally efficient wavelet‐based probability density evolution method
Weifeng Tao,Biswajit Basu,Jie Li +2 more
TL;DR: In this article, the authors proposed a computationally efficient stochastic framework and an associated mathematical formulation to assess the improvement in the vibration response of wind turbines with active structural controllers, where uncertainties in the turbulent wind speed as well as in the structural parameters are considered in the formulation for analyzing the two important (rated and cut-out) wind speed conditions.
