Seismic Performance Reliability of RC Structures: Application of Response Surface Method and Systemic Approach

The present study presents an algorithm that models uncertainties at the structural component level to estimate the performance reliability of RC structures. The method calculates the performance reliability using a systemic approach and incorporates the improved response surface method based on sampling blocks using the first-order reliability method and conditional reliability indices. The re...

Application of Delphi method in site selection of desalination plants

Given the reduced freshwater supplies across the world, seawater desalination is one of the appropriate methods available for producing freshwater. Selecting an optimal location is crucial in the installation of these plants owing to the environmental problems they cause. The present study was conducted to identify optimal locations for installing desalination Plants in the coastal areas of sou...

Equivalence of the virtual-source method and wave-field deconvolution in seismic interferometry.

Seismic interferometry and the virtual-source method are related approaches for extracting the Green's function that accounts for wave propagation between receivers by making suitable combinations of the waves recorded at these two receivers. These waves can either be excited by active, controlled, sources, or by natural incoherent sources. We compare this technique with the deconvolution of th...

Characteristics of ambient seismic noise as a source for 2 surface wave tomography

6 [1] Interstation cross correlations of ambient seismic noise from 1 year of continuous data at periods 7 between 6 and 50 s are used to study the origin of the ambient noise using stations located in Europe, 8 southern Africa, Asia, and three regions within North America. The signal-to-noise ratios (SNR) of 9 Rayleigh waves for positive and negative correlation time lags at periods of 8, 14, ...
