Analysis of Vibrational Induced Structure Considering Rail and Seismic Load Using ETABS
Abstract: In the past, buildings next to railroad tracks were not taken into account when designing them, which resulted in catastrophic damage to the buildings as well as fatalities. For these structures to be designed safely, the vibrational loading must diminish. This study's case study is the Rani Kamlapati railway station in Bhopal, which was renovated by the Bansal Group and is the nation's first private railroad station. They suggested building …
