Abstract

Nepal is susceptible to the potential damage that earthquakes may cause as it is located in a seismically active region. As seen by historical events, Nepal has had a number of devastating earthquakes that have destroyed homes, claimed many lives and damaged properties. This study presents a comparative seismic analysis of a multistoried reinforced concrete building situated on both plain and sloping ground under varying soil conditions, as classified by the Nepal National Building Code (NBC 105:2020). The primary objective is to assess the structural response of the building to seismic forces when subjected to different site conditions and to evaluate the influence of ground slope on seismic behavior. A regular building model was analyzed using response spectrum analysis as per NBC provisions. Key parameters such as base shear, story displacement and story drift, were examined. Results indicate that both soil type and ground slope significantly affect the seismic performance of the structure, with buildings on soft soil and sloped ground showing greater vulnerability. The study emphasizes the importance of considering local soil conditions and topography in seismic design to enhance structural safety and performance.

Keywords
