Analysis Of OGS Building Using Different Structural Systems: Software Based Study

The selection of an appropriate structural system plays a critical role in ensuring the safety, serviceability, and economy of buildings. This study presents a software-based comparative analysis of an OGS (Office-cum-G+ Storey) building modeled using different structural systems, namely Moment Resisting Frame (MRF), Shear Wall System (SWS), and Braced Frame System (BFS). The analysis is carried out using ETABS software in accordance with Indian Standard codes. Key parameters such as lateral displacement, storey drift, base shear, and time period are evaluated. The results indicate that shear wall systems provide superior seismic performance due to increased stiffness, while braced frames offer a balanced solution between strength and economy. The study highlights the importance of software-based analysis in selecting optimal structural systems.
