Canada’s 2020 national seismic hazard model (CSHM 2020) provides estimates for interface Cascadia Subduction Zone (CSZ) earthquakes in southwestern Canada using four ground motion models (GMMs) with equal weights. Two out of the GMMs were derived data primarily from subduction Japan so their use CSHM includes a “Japan-to-Cascadia” factor to account local site conditions. Despite this regional f...

Abstract A site-specific probabilistic seismic hazard assessment (PSHA) was achieved in the area of special economic zone authority Duqm, involving evaluation at bedrock conditions and assurance potential site influence on ground motion bedrock. Appropriate source ground-motion prediction models were selected hazards identified by means 5% damped Uniform Hazard Spectra (UHS) for three return pe...

the near field ground motions have a high amplitude pulse like at the beginning of the seismogram which are significantly influenced by the rupture mechanism and direction of rupture propagation. this type of ground motion cause higher demands for engineering structures and its response spectrum is dramatically different than far field spectra. tabriz is one of the ancient cities in azerbaijan ...

Abstract Deficiencies of the four spectral formats i.e., 2%/50-yr, 5%/50-yr, 10%/50-yr and AASHTO (American Association State Highway Officials) 2009 demand modification for bridge design application in Canada. Among them spectrum is dropped from current investigation as its difference with Canadian Bridge Design Code (CHBDC) 2006 too large to modify. This study introduces an approach calibrati...

In present study, the effects of optimization on seismic energy spectra including input energy, damping energy and yielding hysteretic energy are parametrically discussed. To this end, 12 generic steel moment-resisting frames having fundamental periods ranging from 0.3 to 3s are optimized by using uniform damage and deformation approaches subjected to a series of 40 non-pule strong ground motio...

Taiwan is located on the Pacific seismic belt, and the soil conditions of Taiwan’s offshore wind farms are softer than those in Europe. To ensure safety and stability of the offshore wind turbine supporting structures, it is important to assess the offshore wind farms seismic forces reasonably. In this paper, the relevant seismic and geological data are obtained for Chang-Bin offshore wind farm...
