Nonlinear Seismic Ground Response Analysis in Northeastern India Considering the Comprehensive Dynamic Soil Behavior

Offshore Wind Farms as Additional Coolant Power Sources to Enhance Seismic Resilience of Nuclear Power Plants– a Case Study

“…Since the base of the soil profile is bounded by a hard rock stratum, the ground motions have been applied at the rigid rock base. Similar non-linear 1D GRA studies have been performed on north Indian soil sites by Dammala et al (2017;2019); Puri et al (2021) and Dammala & Krishna (2022), thus further elaborated details are avoided here for brevity.…”

“…However, all the 60 layers are grouped in to six major units with effective stress-based dynamic soil parameters following the recommendation of Zhang et al (2005). The required dynamic soil properties (Gmax; G/Gmax and D) of the site have been adopted from the work of Dammala et al (2019) and Dammala & Krishna (2022) wherein the comprehensive properties have been obtained experimentally for active seismic regions in India.…”

Seismic Response of Monolithic and Precast RC Building for Site-Specific Conditions

“…Paul and Dey [6] did the ground response analysis of a deep soil site in Silchar subjected to the 1997 North-East India earthquake. The local soil profile of Silchar is shown in Fig.…”

“…To overcome this issue, several researchers have performed ground response analysis individually for the different cities across India and estimated the site amplification factors, response spectra, site coefficients, etc. Some of them include works by Ranjan [3] for Dehradun; Mahajan et al [4] for Dehradun; Govindaraju and Bhattacharya [5] for Kolkata; Paul and Dey [6] for Silchar; Boominathan et al [7] for Chennai; Sitharam and Anbazhagan [8] for Bangalore; Raghukanth et al [9] for Guwahati; Phanikanth et al [10] for Mumbai; Chandrasekaran et al [11] for Coimbatore; Shukla and Choudhury [12] for Gujarat ports; Jain and Gupta [13] for Delhi, Dehradun, Kakrapar and Kalpakkam; Jishnu et al [14] for Kanpur; Sitharam et al [15] for lucknow; Mandal et al [16] for Greater Delhi region; Kumar et al [17] for Guwahati; Naik and Choudhury [18] for Goa; Desai and Choudhury [19] for important sites of Mumbai; Elayaraja et al [20] for Coonoor and Ooty; Pandey et al [21] for Uttarakhand; Chatterjee and Choudhury [22] for Kolkata; Chatterjee [23] for Kolkata and many more. Further, Bajaj and Anbazhagan [24] proposed site amplification factors and response spectra for Southern India based on the nonlinear ground response analysis.…”

“…Here, rigid building refers to monolithic RC (MRC) building and the flexible term refers to precast RC (PRC) building. Both the considered buildings are assumed to be situated in Silchar with the PGA of 0.36 g. A real soil profile data of Silchar site is taken from Paul and Dey [6] with the available dynamic soil properties. Moreover, this site is classified as per the Indian site classification and the site classification given by Deoda and Adhikary [26].…”
