Local Site Effects and Liquefaction Analysis of Multilayered Soil
Earthquakes are one of the natural disasters that cause a huge amount of loss in terms of economy and human life. To achieve safety against natural disasters like earthquake, it is necessary to construct the building considering geotechnical problems and structural safety against dynamic forces. The site effects, landslides and liquefaction are dangerous in regard to scale of damage. In the present study, 1D earthquake response analysis has been carried out in different sites of Andhra Pradesh capital seed area of 16.5 km2 in Amaravathi city in Guntur district. To evaluate site effects, borehole data up to a depth of 15 m has been collected. The earthquake time histories were used as input motion. The site amplification at surface has been assessed by using the equivalent linear approach in DEEPSOIL software. In addition to that, response spectra and PGA with depth and Fourier amplitude were assessed. The surface PGA values at surface obtained have been used for liquefaction assessment using SPT-based method. As the study area has high-rise buildings of national importance, findings from the study will be helpful in analysis and design of structures, therefore solving practical challenges in geotechnical and structural engineering
