| dc.description.abstract | Bangladesh is located in a seismically active region, making the seismic design of reinforced
concrete (RC) structures a critical concern for structural safety and resilience. This study
presents a comparative seismic performance analysis of a typical (G+M+08) residential RC
building across all four seismic zones of Bangladesh as defined in the Bangladesh National
Building Code 2020 (BNBC 2020). The building was modeled and analyzed using ETABS
2022 software under equivalent static analysis method. Seismic zone parameters and wind
loads were applied for four representative locations: Jessore (Zone-1), Rajbari (Zone-2),
Tangail (Zone-3), and Sylhet (Zone-4).
Key structural responses—including story displacement, inter-story drift, base shear, and
lateral stiffness—were evaluated and compared across zones. Results indicate that seismic
demands increase progressively from Zone-1 to Zone-4, with Sylhet (Zone-4) showing the
highest values in displacement and base shear. The study also examines the performance of
different framing systems—OMRF, IMRF, and SMRF—under zone-specific loading
conditions.
The findings emphasize the importance of zone-specific design approaches and the adoption
of appropriate lateral load-resisting systems to ensure earthquake-resistant construction in
Bangladesh. All structural drawings were prepared using AutoCAD for accuracy and
compliance with design standards. | en_US |
