Nonlinear Ground Response Analysis: A Case Study of Amingaon, North Guwahati, Assam

The response of any structure depends on its regional seismicity, source mechanism, geology and local soil conditions. This paper reports the outcome of the one-dimensional nonlinear ground response analysis (GRA) conducted for a typical site of Amingaon, Guwahati, using scaled strong motions of various intensities. Soil profiles at the study region comprised mixtures of silts, sands and clays, with a sufficiently high water table. Responses at various soil layers indicate profound influence of the chosen strong motion and local site effects. Maximum and residual strain distributions indicate that there are possibilities of liquefaction at the softer pockets due to an extreme event.
