The document details a study on the analysis and design of a 16-storey RCC building in a hilly area using STAAD.Pro software, focusing on its structural behavior under seismic loading and wind pressure. The research compares the performance of buildings with and without shear walls, revealing that incorporating shear walls significantly enhances stability, reduces lateral displacement, and improves overall seismic performance. Results indicate that buildings with shear walls show better performance metrics, including reduced nodal deflection and increased base shear.
