AbstractThe spatial distribution of soil shear-wave velocity and the fundamental period of vibration were selected as input parameters for the determination of potential seismic site effects in the Saguenay region, Canada. The methodology used in this study involved three clear steps. First, a 3D geological model of the surficial deposits was built taking into consideration the type, spatial distribution and thickness of the deposits. Second, representative average Vs values were determined for each of the major soil units. Finally, the average shear-wave velocity from the ground surface to bedrock (Vsav), the shear-wave velocity of the upper 30 m (Vs30) and the fundamental site resonance period (T0) were calculated over a regular grid for the study area. The results include the spatial distribution of the fundamental site resonance period, the average shear-wave velocity in the first 30 m of the ground and the spatial distribution of National Building Code of Canada seismic soil classes for the Saguenay region. © 2017 Informa UK Limited, trading as Taylor & Francis Group.
Summary(Plain Language Summary, not published)
The spatial distribution of soil shear wave velocity and fundamental period of vibration was determined in the Saguenay region. The methodology was based on a 3D geological modelling of the surficial deposits. Representative average shear wave velocity values were then assigned to each of the major soil units to compute the average shear wave velocity from ground surface to the bedrock, the shear wave velocity of the top 30 meters, and the fundamental site resonance period. The results of this study will be used for generation of seismic scenarios and risk assessment.
